Abstract

A reversible anti-lock motor drive shafting structure belongs to the technical field of optoelectronics, and is disclosed in order to solve the problem in the prior art that the output shaft of a motor may be broken when a cam gear is locked. The reversible anti-lock motor drive shafting structure of the invention comprises a motor gear, a motor, a motor base, a motor shaft sleeve, and a compression structure. The motor is fixed on the motor base. The output shaft of the motor is fixedly connected to the inner hole of the motor shaft sleeve. The outer circular boss of the motor shaft sleeve matches the inner hole boss of the motor gear. The compression structure sleeves the motor shaft sleeve, the side of the compression structure is in contact with the side of the motor gear, and the compression structure compresses the motor gear on the motor shaft sleeve. When the rotation torque of the motor is greater than the friction torque between a gear shaft sleeve and the motor gear, the output shaft of the motor can still drive the shafting structure except the motor gear to rotate. The problem of motor output shaft breaking caused by motor locking is avoided effectively.

Description

technical field [0001] The invention belongs to the technical field of optoelectronics, and in particular relates to a drive shaft system structure of a twistable anti-lock motor. Background technique [0002] Most of the photoelectric loads in the continuous zoom system are driven by gears, such as infrared thermal imaging cameras and visible light cameras, and the motor drives the gear to drive the focusing cam. One of the biggest problems is that the cam itself is easily stuck due to problems such as optical limit failure. At this time, because the rotating shaft of the driving motor is thin, it is easy to break, and there is an urgent need for a shaft structure that can be twisted and anti-locked. [0003] See attached figure 1 , the previous shafting structure mainly includes motor gear 1, shaft steel wire retaining ring 2, cross recessed pan head screw 3, motor 4, motor seat 5, set screw 6 and cam gear 7; motor 4 passes through the cross recessed pan head screw 3 is ...
