Description

WP Worm Gear Reducer (WPWS/WPWX/WPWO/WPWV/WPWT/WPWD): Precision Universal Installation & Quiet Efficient Transmission, Leading Precision Industrial Drive

I. Product Overview: Precision Universal Configuration, Meeting Precision Industrial Needs

Weigao’s WP Series Worm Gear Reducers, covering core precision universal models WPWS, WPWX, WPWO, WPWV, WPWT and WPWD, are high-reliability power transmission devices specially developed for precision industrial scenarios requiring universal installation, low-noise operation, high transmission accuracy and integrated motor matching. Targeting the pain points of traditional and super universal worm gear reducers such as insufficient transmission precision, high operating noise, and complicated motor matching in precision industrial applications, this series integrates precision universal cabinet design, high-precision worm gear meshing technology, silent transmission optimization and integrated motor flange connection technology. It realizes a perfect combination of multi-attitude precision installation, low-noise efficient transmission, integrated power matching and reliable operation, and can stably operate in complex working conditions involving precision speed control, noise-sensitive environments, compact layout and continuous light-to-medium load. As a core transmission component for key equipment in precision industrial fields, this precision universal WP series is widely applied in precision automation equipment, food packaging machinery, medical auxiliary equipment, light industry textile machinery and other industries, providing high-precision and reliable power support for global precision industrial production projects. The product has passed international certifications such as ISO 9001 quality management system certification, CE certification and IP65 protection certification, and is trusted by more than 50 countries and regions for its excellent precision scenario adaptation performance.

II. Core Advantages: Five Precision Transmission Strengths, Defining Precision Universal Standards

1. Precision Universal Cabinet Design, Multi-Attitude Flexible Installation

The series adopts a precision universal integrated cabinet structure optimized by finite element analysis, and the cabinet is made of high-strength cast iron (HT250) with uniform wall thickness and optimized reinforcing rib distribution, ensuring structural stability while realizing multi-attitude precise installation. The six core models cover diversified input-output attitudes to meet precision layout needs: WPWS (universal type, input shaft upward), WPWX (universal type, output shaft downward), WPWO (universal type, output shaft upward), WPWV (universal type, input shaft downward), WPWT (universal type, input shaft upward), WPWD (universal type, with motor flange input connection) . Multiple sides of the cabinet are equipped with standardized precision mounting holes, which can flexibly switch between horizontal, vertical, wall-mounted and other installation modes, and the installation positioning accuracy error is ≤0.1mm, which effectively ensures the overall precision of the equipment. This precision universal design is especially suitable for compact layout scenarios of precision equipment, reducing the impact of installation errors on transmission precision.

2. High-Precision Silent Transmission, Adapting to Sensitive Scenarios

The series adopts high-precision worm gear transmission pair design, the worm is made of 40CrNiMoA high-strength alloy steel, processed by integral forging, quenching and tempering, and super-precision grinding, with surface hardness up to HRC 58-62 and tooth surface roughness ≤Ra 0.4μm. The worm gear is made of high-wear-resistant tin bronze (ZCuSn10Pb1) with precision tooth profile modification, and the meshing contact area reaches more than 90%, realizing smooth force transmission without impact. At the same time, the optimized worm helix angle design and silent bearing configuration effectively reduce meshing noise and rotating noise. The no-load operating noise is ≤55dB, and the load operating noise is ≤63dB (measured at 1m distance), which is far lower than the industry average. This silent performance makes it especially suitable for food packaging, medical equipment, laboratory instruments and other noise-sensitive scenarios, avoiding noise interference with production or use environments. The transmission accuracy error is ≤0.2arcmin, which can precisely match the speed control needs of precision equipment.

3. Integrated Motor Flange, Efficient Precision Matching

WPWD model in the series is equipped with integrated motor flange, and other models support optional flange kits, which adopt international standard flange sizes (compatible with IEC standards) and can be directly matched with 0.37-37kW standard three-phase asynchronous motors, servo motors and variable frequency motors. The flange and cabinet are integrally cast, with high coaxiality, avoiding transmission precision loss caused by assembly errors. For servo motor matching scenarios, the series can be customized with high-rigidity shaft extension design to ensure the dynamic response performance of the transmission system. This integrated matching design not only simplifies the equipment assembly process, shortens the debugging cycle, but also improves the overall precision and stability of the transmission system, reducing the user's procurement and maintenance costs.

4. Enhanced Sealing & Lubrication, Stable Long-Term Operation

The sealing system adopts enhanced double-lip oil seal + labyrinth seal combined design, with high-temperature resistant and oil-resistant sealant at the cabinet joint, achieving IP65 protection level. It can effectively prevent the intrusion of dust, water vapor, cutting fluid and other impurities in precision workshop environments, and avoid lubrication failure caused by oil leakage. The product adopts optimized forced splash lubrication, and the built-in oil filter ensures the cleanliness of lubricating oil. The centralized oil filling port and transparent oil level observation window facilitate daily lubrication management. Using 220#/320# special long-acting synthetic worm gear oil with good anti-wear and anti-oxidation performance, the product can work normally in the operating temperature range of -15℃ to +110℃, and the rated service life reaches more than 15 years under normal maintenance conditions.

5. Compact Structure & High Rigidity, Space-Saving & Anti-Impact

The precision universal cabinet adopts compact structure design, which is 20% smaller in volume than the super universal models with the same torque, and can be easily embedded into the internal layout of precision equipment, improving space utilization. The key stress parts of the cabinet are thickened and reinforced, with torsional rigidity ≥3800Nm/arcmin, which can effectively resist the impact load generated during the start-stop and operation of precision equipment. The bearing adopts high-precision deep groove ball bearings with double-sided sealing, which can bear large axial and radial loads, ensuring stable operation of the transmission system under intermittent impact load conditions. The overall weight of the product is reduced by 15% compared with similar models, which is conducive to reducing the overall load of precision equipment.

V. Installation and Maintenance: Scientific Operation, Maximizing Performance

During installation, select the corresponding model according to the equipment layout (input/output shaft attitude) and power matching requirements. For precision installation scenarios, ensure that the coaxiality error between the reducer and the motor (or other power sources) is ≤0.08mm to avoid affecting transmission precision. For WPWD models with integrated motor flanges, ensure that the motor mounting surface is closely attached to the flange without gaps, and use torque wrenches to fasten the connecting bolts evenly. Select the appropriate lubricating oil according to the working conditions: use 220# special synthetic worm gear oil for normal temperature and general load, and 320# high-temperature resistant synthetic worm gear oil for high temperature and heavy load. Regularly check the oil level, oil quality and sealing performance; replace the lubricating oil after the first 2000 hours of operation, and perform comprehensive maintenance every 6000 hours thereafter, including checking worm gear meshing status, bearing temperature and fastener tightness. If abnormal phenomena such as excessive noise, vibration, oil leakage or overheating occur during operation, stop the machine immediately for inspection and troubleshooting.
