The slewing reducer is an upgraded product of the slewing bearing, usually composed of a worm, turbine slewing bearing, housing, and power source. The shell is made of high-quality cast steel and has very high strength. The worm gear and worm gear are made of 42CrMo and lightened by glow ions. The wear resistance strength is higher than that of the domestic traditional gas nitrided 50Mn material. Stronger than hardness and longer service life. This product can be used in mechanical equipment such as flatbed trucks, wooden cranes, single-column cranes, beam lifting machines, truck-mounted cranes, aerial work vehicles, solar-tracking solar energy, automation equipment, etc.; in the solar photovoltaic power generation industry, slewing drive devices are generally equipped DC planetary gear motors or AC gear motors are mainly used; hydraulic motors are mainly used as power drive systems on construction machinery.

Specification model of slewing drive pair

XZWD Small Slewing Drive 3inch SE3 for Solar Tracking System

The specifications and models of the slewing drive vary in size, including SE/PE/ZE/WE/VE/PVE/ZVE/ZDE, etc. 3", 5", 7", 9", 12", 14", 17", 21", 25" and other specifications 15161590024. "SE" in the model label stands for: the English abbreviation Q370571775 of Slewing and Enclose.

Because the core component adopts slewing bearing, it can bear axial force, radial force and tipping moment at the same time. The slewing drive pair is easy to install, easy to maintain, and saves installation space to a greater extent. This product can be widely used in construction machinery and new energy fields such as heavy-duty flatbed trucks, container cranes, truck-mounted cranes, aerial work trucks, solar-powered solar generator systems, etc.


Code description of slewing drive


S(E) – S open type huizhuanqudong, SE fence type huizhuanqudong.

XX-product size, such as: 3", 5", 7", 9", 12", 14", 17", 21", 25" means approximate center distance of raceway.

XX (S)-XX reduction ratio S teeth are not quenched, none-means the teeth are quenched.

2H-2 means double worm drive, no- means single worm drive; H means the non-input end of the worm is a hexagonal head, and E- means the non-input end of the worm has an encoder, and no- means the non-input end of the worm is a stuffy cover.

B-Worm input mounting hole is 6B spline, 12 represents worm input hole diameter Φ12mm, 16 represents worm input hole diameter Φ16mm, 25 represents worm input hole diameter Φ25mm, etc.; R (L) Motor or motor installation direction: right or left side.

XXX (E)-Motor and hydraulic motor specifications, E- means that the motor has a built-in encoder, no-means that the motor does not have a built-in encoder.

The final output speed of the XXX-huizhuanqudong device, such as: 001, 010, and 100 are respectively 100 times the actual output speed, that is, the actual output speed is: 0.01rpm, 0.1rpm and 1rpm.



"SE17-102S- 12R-24010-REV.A" huizhuanqudong device, closed box, raceway center distance is 17", reduction ratio is 102:1, tooth is not quenched, input mounting hole is flat key Φ12mm, right side installation , DC 24V motor without built-in encoder, huizhuanqudong device finally output speed 0.1rpm, A version number.
