Abstract
The utility model relates to a worm and gear speed reduction motor, in particular to a dual-binding ring shaft locating structure worm and gear speed reduction motor, which comprises a shell, a front end cap, a back end cap, a motor shaft, and a rotor arranged on the motor shaft, wherein the motor shaft is rotatablely supported on the front cap and the back cap by a front bearing and a back bearing. A worm and gear structure is arranged at the output end of the motor shaft, and the other end of the motor shaft is provided with an electromagnetic brake and an encoder. The inner ring of the bearing is fixed on the motor shaft by shoulder rings which are separately arranged at the two ends of the inner ring, and the front bearing is fixed on the front end cap by a screw. The location of the motor shaft and the end caps is reliable, and the operation of the motor is steady, the utility model solves the problems that the current worm and gear speed reduction motor has a large applied force on the motor shaft during the operation of the worm and gear speed reduction structure, which easily causes the motor shaft axially moving against the end caps, effects the performance of the motor, and even damages the motor.
Description
Technical field
The utility model relates to the worm and gear reducing motor, the two snap ring location structures of particularly a kind of worm and gear reducing motor axle.
Technical background
A kind of motor (CN 200410074746.3) with turbine and worm decelerator, be provided with motor, turbine and worm decelerator, the armature shaft of motor is one with coaxial being in transmission connection of the worm screw of turbine and worm decelerator, the armature shaft outer end and the worm screw outer end that are positioned on the same axis are equipped with block bearing respectively, the worm screw diameter is 1.5～6 times of armature shaft diameter, and worm screw is equipped with block bearing at its end near armature shaft.There are the following problems for the motor of said structure: turbine and worm decelerator active force to motor shaft in operation process is bigger, causes moving axially between motor shaft and the end cap easily, influences motor properties, even causes the damage of motor.
Summary of the invention
The utility model purpose is to provide locatees between a kind of motor shaft and the end cap reliably, the two snap ring location structures of the worm and gear reducing motor axle of motor rotation stable performance, it is bigger to have solved turbine and worm decelerator active force to motor shaft in operation process that the motor of existing band turbine and worm decelerator exists, cause moving axially between motor shaft and the end cap easily, influence motor properties, even cause the problems such as damage of motor.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: comprise casing, front end housing, rear end cap, motor shaft and be located at rotor on the motor shaft, motor shaft is supported on the front and rear cover by the front and back bearings rotation, the output of motor shaft is provided with turbine and worm decelerator, the other end of motor shaft is provided with electromagnetic brake and encoder, the inner ring of described fore bearing is fixed together by shaft block ring and the motor shaft that is separately positioned on the inner ring two ends, and the outer ring of fore bearing is fixed together by screw and front end housing.The inner ring of fore bearing by its two ends shaft block ring and the motor shaft axial restraint together, the outer ring of fore bearing then is fixed together by screw and front end housing, make motor axial displacement be controlled in the less displacement range of fore bearing Internal and external cycle, guarantee the operate as normal of electromagnetic brake and encoder, make motor properties stable, reduced the damaged probability that motor causes because of moving axially of motor shaft.Wherein, can directly contact fixing with the fore bearing cycle surface by the head inner face of screw between fore bearing outer ring and the front end housing; Can increase between screw head and front end housing also that packing ring or pad contact with the fore bearing cycle surface and the axial restraint of realizing itself and front end housing.
As preferably, described front end housing is provided with the stepped hole that matches with the fore bearing outer ring, and described screw is a pan head screw, and the thread segment of pan head screw is threaded with front end housing, and the coiled hair inner face of pan head screw contacts with the end face of bearing outer ring.Wherein, the bottom surface of stepped hole contacts with an end face of fore bearing outer ring, realize unidirectional location vertically between fore bearing outer ring and the front end housing, pan head screw coiled hair inner face is located the fore bearing outer ring vertically with contacting then of bearing outer ring end face from another direction, thereby will realize axial two-way location between fore bearing outer ring and the front end housing.
Therefore, it is reliable to the utlity model has between motor shaft and the end cap location, characteristics such as motor rotation stable performance.
