It realizes a perfect combination of multi-orientation universal installation, diversified output matching, reliable efficient transmission and easy equipment docking, and can stably operate in complex working conditions involving multi-angle layout, special output docking, intermittent impact load and harsh workshop environment. As a core transmission component for key equipment in complex industrial fields, this universal WP series is widely applied in heavy-duty conveyors, automatic production line actuators, special processing machinery and other industries, providing high-compatibility and reliable power support for global complex 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 complex scenario adaptation performance.
II. Core Advantages: Five Complex-Scenario Transmission Strengths, Defining Universal Adaptation Standards
1. Universal Cabinet Design, Multi-Orientation Installation Adaptation
The series adopts a universal rectangular cabinet structure with optimized topology design, and the cabinet is made of high-strength cast iron (HT250) with uniform wall thickness and dense internal reinforcing ribs, ensuring structural rigidity while realizing multi-orientation installation. The five core models cover diversified input-output attitudes to meet complex layout needs: WPDX (with motor flange, output shaft downward), WPDO (with motor flange, output shaft upward), WPKA (shaft hole output, input shaft downward), WPKS (shaft hole output, input shaft upward), WPDKA (with motor flange, shaft hole output, input shaft downward) . Multiple sides of the cabinet are equipped with standardized mounting holes, which can flexibly switch between horizontal, vertical, wall-mounted and other installation modes without additional adapter brackets. This universal design reduces the difficulty of complex equipment layout by 40% compared with traditional models, and significantly improves space utilization.
2. Shaft Hole/Flange Dual-Output, Diversified Docking Compatibility
The series innovatively adopts dual-output mode compatibility design, covering shaft hole output and traditional solid shaft output to meet different equipment docking needs. WPKA and WPKS models adopt high-precision shaft hole output design, with inner hole precision up to H7 level, which can be directly connected with the equipment input shaft through expansion sleeve, realizing high-coaxiality transmission without coupling. WPDX and WPDO models adopt solid shaft output with integrated motor flange, which is convenient for direct docking with standard actuators. WPDKA model integrates motor flange and shaft hole output, realizing dual-compatibility of power input and equipment docking. The worm is made of 40CrNiMoA alloy steel, processed by quenching and tempering, precision grinding, with surface hardness up to HRC 58-60. The worm gear is made of wear-resistant tin bronze (ZCuSn10Pb1), with optimized tooth profile design, transmission efficiency up to 83%-91% (depending on model and reduction ratio), and stable operation under variable load conditions.
3. Integrated Motor Flange, Efficient Power Matching
WPDX, WPDO and WPDKA models in the series are equipped with integrated motor flanges, which adopt international standard flange sizes and are compatible with 0.75-45kW standard three-phase asynchronous motors and servo motors. They can be directly connected with motors without additional coupling components, reducing installation errors and improving transmission stability. The flange and cabinet are integrally cast, with high structural strength and good vibration resistance. For WPKA and WPKS models without integrated flanges, standard input shaft extension design is adopted, which can be flexibly matched with various power sources through couplings. This diversified power matching design improves product universality and reduces user procurement and assembly costs.
4. Enhanced Sealing Protection, Harsh Environment Adaptation
The sealing system adopts enhanced double-lip oil seal + labyrinth seal combined design, with high-elasticity O-rings and reinforced sealant at the cabinet joint, achieving IP65 protection level. It can effectively prevent the intrusion of dust, water vapor, cutting fluid and corrosive media in harsh workshop environments, and avoid lubrication failure caused by oil leakage. The shaft hole output end is equipped with a special sealing sleeve, which ensures sealing performance while not affecting the docking of the equipment input shaft. The product adopts forced splash lubrication, and the optimized internal oil circuit ensures sufficient lubrication of all transmission components. It can work normally in the operating temperature range of -15℃ to +120℃, adapting to various harsh industrial environments.
5. High Rigidity & Anti-Impact, Stable Long-Term Operation
The universal cabinet adopts topology optimization design, and the key stress parts are thickened and reinforced, with torsional rigidity ≥3500Nm/arcmin, which can effectively resist the impact load generated during equipment startup and operation. The worm shaft adopts integral forging forming technology, with enlarged diameter design, which improves the bearing capacity of the shaft system. The bearing adopts deep groove ball bearings with high load capacity, which can bear large axial and radial loads. Under the condition of 1.5 times rated torque impact, the transmission accuracy deviation is ≤0.2arcmin, ensuring stable operation. The rated service life of the product reaches more than 15 years under normal maintenance conditions, reducing the frequency of equipment maintenance and replacement.

V. Installation and Maintenance: Scientific Operation, Maximizing Performance
During installation, select the corresponding model according to the equipment layout and output docking requirements. For shaft hole output models (WPKA/WPKS/WPDKA), ensure that the coaxiality error between the equipment input shaft and the reducer shaft hole is ≤0.08mm, and select the appropriate expansion sleeve according to the shaft diameter. For models with integrated motor flanges (WPDX/WPDO/WPDKA), ensure that the motor mounting surface is closely attached to the flange without gaps. 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.
