Abstract
A kind of single phase induction motor The gear deceleration structure is the utility model is related to, including protecgulum, the first oil sealing, the first deep groove ball bearing, output shaft gear, the 3rd deep groove ball bearing, little gear, the second oil sealing, the bonnet being sequentially connected from front to back；Also include the second deep groove ball bearing, duplicate gear, the 4th deep groove ball bearing set gradually between the protecgulum and bonnet；The duplicate gear engages close to the gear of protecgulum with output shaft gear, the gear of close bonnet engages with little gear, simultaneously, also include machine shaft and flat key, the machine shaft inserts from reduction box bonnet, until the 3rd deep groove ball bearing center, the flat key are arranged between little gear inwall and machine shaft outer wall.Machine shaft of the present utility model is connected on the same axis, by bearing with output shaft gear so that the reduction box volume of reduction box volume ratio conventional in-line gear structure significantly reduces in the case of same speed reducing ratio, has saved material, has reduced cost.
Description
Technical field
It the utility model is related to single phase induction motor technical field, more particularly to a kind of single phase induction motor The gear deceleration knot
Structure.
Background technology
Single phase induction motor is widely used in various food machinerys, office automatic articles for use, automatic industrial production equipment
Etc. various occasions, specific occasion lower gear slowing-down structure is the core component of output shaft rotation power output.Due to single-phase induction
Motor uses power-frequency voltage, and electric motor starting torque is smaller, and motor speed should not adjust.Some need the slow-speed of revolution, and high pulling torque is set
It is standby will be unable to be dragged with single phase induction motor；But traditional The gear deceleration structure is spur gear in-line arrangement deceleration knot
Structure, reduction box volume is larger, and not on the same axis, gear noise is difficult to control, installation difficulty for power output shaft and motor shaft
Cost is higher.
Utility model content
In order to solve the above-mentioned technical problem, there is provided a kind of reduction box small volume, noise are small, the simple single-phase induction electricity of assembling
Machine The gear deceleration structure, the utility model provide following technical scheme：
A kind of single phase induction motor The gear deceleration structure, including be sequentially connected from front to back protecgulum, the first oil sealing, first
Deep groove ball bearing, output shaft gear, the 3rd deep groove ball bearing, little gear, the second oil sealing, bonnet；Between the protecgulum and bonnet
Also include the second deep groove ball bearing, duplicate gear, the 4th deep groove ball bearing set gradually；Second deep groove ball bearing and
Four deep groove ball bearings are sheathed on the both sides of duplicate gear and are respectively cooperating with protecgulum and set with bonnet respectively, and the duplicate gear leans on
The gear nearby covered engages with output shaft gear, is engaged close to the gear of bonnet with little gear, meanwhile, in addition to machine shaft and
Flat key, the machine shaft insert from reduction box bonnet, until the 3rd deep groove ball bearing center, the flat key are arranged in little gear
Between inwall and machine shaft outer wall.
Further, the protecgulum and bonnet are molded using aluminium die-casting.
Further, the protecgulum and bonnet are bolted to connection.
The beneficial effects of the utility model are：
(1), machine shaft and output shaft gear on the same axis, are connected by bearing, reduction box volume ratio in-line arrangement
The reduction box volume of gear structure significantly reduces in the case of same speed reducing ratio；Casting aluminium material has been saved, has reduced cost；
(2), output shaft gear and machine shaft are connected by bearing, are easy to process and are assembled, gear noise is smaller.

Not Pei He protecgulum 1 set with bonnet 12, the duplicate gear 7 engages close to the gear of protecgulum 1 with output shaft gear 4, after
The gear of lid 12 engages with little gear 8, meanwhile, in addition to machine shaft 13 and flat key 11, the machine shaft 13 is from reduction box
Bonnet 12 inserts, until the center of the 3rd deep groove ball bearing 6, the flat key 11 are arranged in outside the inwall of little gear 8 and machine shaft 13
Between wall.The protecgulum 1 and bonnet 12 are molded using aluminium die-casting, and bearing chamber, oil sealing room are processed using milling method,
The output shaft gear 4 is using forging, smart car, gear hobbing manufacture, and the duplicate gear 7 is using forging, smart car, welding, gear hobbing system
Make, the little gear 8 is using forging, smart car, gear hobbing manufacture, and the machine shaft 13 is using smart car, fine grinding manufacture, remaining part
It is standard component.The protecgulum 1 and bonnet 12 are bolted to connection.
The machine shaft 13 of the present embodiment on the same axis, is connected, reduction box volume with output shaft gear 4 by bearing
Reduction box volume than in-line arrangement gear structure significantly reduces in the case of same speed reducing ratio, has saved casting aluminium material, has reduced
Production cost.
Using above-mentioned foundation the utility model desirable embodiment as enlightenment, pass through above-mentioned description, relevant staff
Various changes and amendments can be carried out in the range of without departing from this item utility model technological thought completely.This item is practical
New technical scope is not limited to the content on specification, it is necessary to determines that its is technical according to right
Scope.
