Micro Slew Rate Limited 25 Inch SE25 Enclosed Housing Slew Drive for Solar Tracker

5 0 Reviews
The internal slewing bearing of SE Series is helical tooth, WEA series slewing bearing is turbine tooth , so the WEA Series bearing capacity is larger than SE series!
Availability:
Quantity:
  • SE25

  • XZWD

  • 8483409000

SE slew drive design:


· Exhibits high torque at low output speeds and transmits high tilting moments, axial and radial loads

· Attains highest capacity with smallest diameter configuration

· Flat design, due to tangentially located drives

· Provides high torque transmission (however, the duty must be taken into consideration)

· Self-locking and non-self-locking Slew Drives are available

· Non-self-locking Slew Drives can be equipped with locking brakes

· Consider the position of the output shaft when selecting the Slew Drive

· Not recommended in case of continuous vibrations and heavy impact loading

Selecting a suitable design size in the limiting load

A suitable Slew Drive is selected iteratively. For a pre-selected Slew Drive, (e.g. WD-L 0478/3-04995), an operation load point is calculated depending on external loading, the application service factor and the raceway diameter DL

Loading is permissible for raceway and bolt connection, provided that the operating point lies below the limiting load line of a preselected Slew Drive.

If the operation load point lies above the corresponding limiting load line, a Slew Drive with higher power rating must be selected, for which the limiting load line lies above the current operation load line. For the newly selected size, the operation load point must be calculated again and the permissibility of the new operation load point must be verified against the limiting load line. On the contrary, if the operating load point also lies below the limiting load line of a smaller size, then, for this size, permissibility of the newly calculated operating point can be verified within the limiting load diagram.

 

Now XZWD has 109 pcs production equipment with annual production capacity of slewing bearing 40000pcs/year.

 

In 2022, it will have 167pcs production equipment in new plant with annual production capacity of slewing bearing 70000pcs/year.
