AI Technical Summary

Technical Problem

The main motor gearbox and output shaft are subjected to a great lateral force during operation, resulting in serious wear, and the prior art is difficult to effectively prevent the aggravation of wear.

Method used

A housing frame is designed to limit the swing of the drive shaft by installing bearing seats and limit wheels at both ends of the drive shaft, and adjust the spacing of the limit wheels by adjusting the screw and lock nuts to accommodate drive shafts of different diameters.

Benefits of technology

It effectively reduces the swing of the drive shaft when rotating, enhances the protection of the gearbox bearings, and extends its service life.

Abstract

The utility model belongs to the technical field of mobile phones, and particularly relates to a main motor gearbox anti-abrasion aggravation shell frame which comprises a mounting base, a driving motor and a driving shaft, the driving motor is fixed at one end of the upper surface of the mounting base through a bolt, and the driving shaft is connected with the power output end of the driving motor. A bearing seat is movably mounted on the surface of the mounting base, a fixing frame is welded to the surface of the end, away from the driving motor, of the mounting base, an adjusting lead screw is annularly arranged in an inner cavity of the fixing frame, a limiting wheel is movably connected to the end of the adjusting lead screw and abuts against the surface of a driving shaft, and one end of the driving shaft is inserted into an inner cavity of the bearing seat. When the driving shaft rotates, the two ends of the driving shaft can be limited through the bearing seats and the limiting wheels, when the driving shaft rotates, swing can be reduced, meanwhile, transverse force borne by the driving shaft can be relieved, protection on a reduction gearbox bearing can be improved, and the service life of the reduction gearbox bearing can be prolonged.
