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

Seeing accompanying drawing 1, conventional shafting structure mainly includes motor gear 1, axle-steel silk back-up ring 2, cross recess coiled hair spiral shell Nail 3, motor 4, motor cabinet 5, holding screw 6 and cam wheel 7;Motor 4 is anchored on motor cabinet 5 by Cross Recess Head Screw 3 On, motor output shaft is anchored on motor gear 1 by the holding screw 6 of three circumference uniform distributions, and holding screw 6 passes through axle-steel Silk back-up ring 2 limits its radial displacement.Motor 4 rotarily drives motor gear 1 and rotates, motor gear and cam wheel engagement, and then Cam wheel 7 is driven to rotate.The greatest problem of this kind of shafting structure existence is when cam wheel 7 is because a variety of causes is stuck Waiting, motor 4 still drives motor gear 1, of long duration motor output shaft can be caused to fracture, thus causes whole failure mechanisms.
Summary of the invention
It is an object of the invention to propose one and can reverse anti-lock motor driving shaft architecture, solve prior art and exist Cam wheel stuck time motor output shaft can be caused to fracture problem.
For achieving the above object, the one of the present invention can reverse anti-lock motor driving shaft architecture include motor gear, Motor, motor cabinet, motor shaft sleeve and compressing structure;
Described motor is fixed on motor cabinet;The output shaft of described motor and the fixing connection of described motor shaft sleeve endoporus, institute Outer circular bosses and the described motor gear endoporus boss of stating motor shaft sleeve coordinate, and described compressing structure is enclosed within described motor shaft sleeve On, described compressing structure side and described motor gear contacts side surfaces, by described compressing structure, described motor gear is compressed On described motor shaft sleeve.
Described compressing structure includes gear dottle pin, heavy-duty spring packing ring and gear trim ring;Described gear dottle pin, heavy-duty spring Packing ring and gear trim ring axially set gradually along motor shaft sleeve in motor gear side, described gear trim ring and described motor shaft sleeve Threaded.
Described motor is fixed by screws on motor cabinet.
Described shafting structure also includes holding screw, and the output shaft of described motor is by holding screw and described motor shaft sleeve Fixing connection.
Described motor shaft sleeve endoporus is provided with step, the output shaft end of described motor and the endoporus of described motor shaft sleeve Step coordinates, and the output shaft of described motor is joined pointed orifice of pinching, described holding screw and described center hole and overlaps.
Operation principle: a kind of gear trim ring reversing anti-lock motor driving shaft architecture of the present invention and motor shaft sleeve Being threaded connection, gear trim ring compresses heavy-duty spring packing ring, forces heavy-duty spring packing ring to shrink and produces axial compressive force, compresses tooth Wheel dottle pin, so that motor gear compresses with motor shaft sleeve.Motor output shaft drive motor axle sleeve rotates.Motor shaft sleeve passes through side Face moment of friction drives motor gear, and motor gear drives the cam wheel of the O-E Payload of engagement to realize rotating by gear pair Motion.
The invention have the benefit that the one of the present invention can be reversed anti-lock motor driving shaft architecture and achieve and can turn round Turn the motor driving shaft architecture form of anti-lock, in the case of motor gear is stuck, motor output shaft driven gear axle sleeve Rotating, when electric machine rotation moment is more than the moment of friction between gear bush and motor gear, motor output shaft drives except electricity Shafting structure outside machine gear still rotates.Efficiently avoid the problem that the motor output shaft that motor rotation blockage causes fractures. This shafting structure compact conformation, technique is simple, it is simple to debuging and keep in repair, practical value is strong.
