Description

A kind of permanent magnet motor structure

Technical field

The utility model discloses a kind of permanent magnet motor structures, belong to equipment transmission technical field, comprising plastic extruder, The drive technology of the equipment such as oil press, helical feed.

Background technique

In many mechanical equipments, to meet equipment operation and the requirement of applying working condition, usually require a kind of slow-speed of revolution, The driving equipment of large torque, in the conventional technology, using high-speed motor band speed reducer structure, motor runs at high speed, and passes through shaft coupling Device is connected with speed reducer, by speed reducer multi-change speed, after reducing revolving speed, output large torque to application apparatus.

The slow-speed of revolution, large torque driving equipment are in equipment running process, other than torque to be transmitted, it is also possible to need Bear the equipment such as very big axial force, such as plastic extruder, oil press, helical feed.For this purpose, common solution has three Kind: 1. increase bearing block, are directly delivered to axial force on base by bearing block, any axial force is not subject on output shaft, Such mode needs larger space, and also to increase bracket for higher equipment from the ground；2. modifying speed reducer structure, change With thrust bearing, but since thrust bearing size is different from plain bearing size, it is therefore desirable to modify cabinet and make, but cabinet is most For cast member, need to re-mold, cost is too big；3. selecting special reduction gear, such as ZLYJ rubber and plastic special reduction gear, Ke Yicheng By large axial force, but special reduction gear structure is single, and speed ratio is less and installation form is restricted, and versatility is poor, speed ratio Range is smaller, and versatility is not strong.

Above-mentioned driving system of speed reducer transmission efficiency is low, mechanical loss is big, power consumption is big, performance is lower, volume is big, peace Dress is difficult, and speed reducer high gear part is easy to damage, noise vibration is big, calorific value is big, poor reliability.

In recent years, magneto technology continues to develop mature, and permanent magnet direct driving motor also has more answer in each field With motor uses low rotation speed large torque design scheme, directly drives equipment operation, high reliablity, high-efficient, power consumption subtract It is small.But in the equipment for needing to bear large axial directional load, magneto generallys use common thrust bearing to convert axial force, The motor of this structure has the drawback that: in motor operation course, thrust bearing due to bearing biggish responsive to axial force, Thrust bearing a large amount of heat because friction generates, and lesser bearing chamber structure and the poor lubricating grease of mobility cannot in time rapidly Ground be thrust bearing heat dissipation, cause bearing running hot to be damaged so that motor can not long-term work, simultaneously because thrust bearing and motor It is made of one, when damage of thrust pad, it is necessary to which thrust bearing can be replaced by disassembling entire magneto.

The utility model is in order to solve the problems, such as that existing magneto bears axial force, for this purpose, it is proposed that one kind has The permanent magnet motor structure of thrust packet.

In order to achieve the above objectives, the utility model the following technical schemes are provided:

A kind of permanent magnet motor structure, including magneto and thrust package, the magneto include shell, stator, rotor, The shell is in seal shape, which is fixed on the inside of the shell, which can revolve in the inside of the shell with respect to the stator Transhipment is dynamic and the rotor has a motor shaft and extends outside the shell, which includes thrust chartered plane seat, thrust bearing, output Axis, the thrust chartered plane seat are attached with the housing forward end, and thrust chartered plane seat output end is equipped with thrust bearing room, the thrust bearing Interior is equipped with thrust bearing, which is equipped with output shaft, which is equipped with connecting hole, The output shaft input terminal is attached with the motor shaft.

Preferably, which is thrust automatic aligning roller bearing or spherical roller thrust bearing.

Preferably, which is equipped with spring bearing room, which is equipped with bearing, the output shaft Input terminal is pierced by the bearing and is attached with the motor shaft.

Preferably, which is equipped at least one keyway.

Preferably, which is hollow shaft, which is equipped with internal keyway, which is equipped with and this The connecting key of hollow shaft cooperation.

Preferably, which is protrusion axle, which is equipped with connecting key, which is equipped with indent Hole, the concave hole are equipped with the connection keyway cooperated with the protrusion axle.

The utility model has the beneficial effect that compared with prior art

1. magneto is high-efficient, reliable performance, with thrust package integrated design, compact-sized, easy to install, volume It is small, light-weight, save material cost, convenient for installation and maintenance；Speed reducer is eliminated, failure rate is effectively reduced, mitigates calorific value, is low Vibration, can prolong the service life at low noise, and cost performance is high.

2. thrust package creation section is installed, it can be directly mounted on magneto, have no need to change magneto knot Structure enables magneto to bear large axial force, and this body structure of the thrust package is simple, and number of parts is few, is convenient for tissue Production and inventory, convenient maintenance and replacement.

3. thrust package connecting hole is spline connection, hole size can be customized according to customer requirement, and repairs replacement Step is simple.
