Description
Technical field
The utility model is related to motor braking technical fields, specifically a kind of motor unidirectional damping mechanism.
Background technology
The motor of the prior art usually connects retarder and is used together, and the output shaft of retarder drives other mechanisms again, subtracts
It is deceleration mechanism, such as worm gear mechanism inside fast device.One end of the output shaft of motor is to connect retarder to drive load
, naturally it is also possible to directly connected with load, and the other end is then idle running, this one end is often wrapped in the shell of motor,
Commonly referred to as tailing axle.
However when closing motor, motor can be rotated further due to certain inertia, and this inertia, which may drive, to be subtracted
Fast device directly makes load work on a bit of time, and many this inertia of occasion are harmful, are such as mounted on lifting gear
In motor, stroke can be exceeded if braking not in time.The braking of current motor generally uses electromagnetism to stop, and electromagnetism is stopped in motor
The effect that machine shaft plays braking can be nipped by being powered after closing, and electromagnetism brake is used to need to be powered, and due to its structure
The more complex personnel generally used are difficult to repair, and cost is also relatively high.In addition in motor-driven lifting gear, work as rising
In the process, motor or power-off suddenly are closed, the cargo above carried overloads very much again, since gravity can decline and keep motor anti-
Turn.
The technical issues of being directed to the prior art at present, there are also technologies to be arranged damping mechanism to generate system in motor tailing axle
Dynamic effect, but such mechanism can generate larger resistance in motor normal operation, to increase power consumption.
Utility model content
In view of this, the technical problems to be solved in the utility model is to provide and a kind of realizing that the motor of unidirectional damping is unidirectional
Damping mechanism reduces the damping power consumption of motor.
The technical solution of the utility model is to provide a kind of motor unidirectional damping mechanism with lower structure, including list
It is installed on the tailing axle of motor to bearing, damping piece and fixed shell, the unilateral bearing, the damping piece is sheathed on list
To on bearing, the fixed shell encases the damping piece, and damping piece is fixed.
As an improvement, the damping piece is rubber pad, include the rubber sleeve coordinated with unilateral bearing, and be arranged in institute
State the locating ring ear at rubber sleeve edge.
As an improvement, the fixation shell includes case and the fixed ring at case edge is arranged, it will by fastener
The fixed ring is fixed on the locating ring ear on the shell of the motor.
Using the above structure, the utility model has the following advantages compared with prior art：The one-way shaft of the utility model
The tailing axle for being installed on motor shaft is held, the tailing axle with unilateral bearing is inserted in damping piece, it will by fixed shell and fastener
The damping piece is fixed on the shell of motor, motor shaft rotation, in the steering that need not be damped, then motor shaft and the list
It is relatively rotated to bearing, i.e., bearing outer ring is substantially motionless because of the damping of damping piece, and bearing inner race is then rotated with motor shaft, no
It will produce damping action；In another steering, then since unilateral bearing can not rotate, the driving force of motor can be unidirectional
Frictional force is generated between bearing and damping piece so that motor shaft drives bearing movable in the case where being damped, at this time motor
Axis is opposite with the unilateral bearing motionless.The utility model realizes the unidirectional damping to motor, reduces unfavorable damping to drop
Low-power consumption.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model motor unidirectional damping mechanism.
As shown in the figure 1, unilateral bearing, 2, damping piece, 2.1, rubber sleeve, 2.2, locating ring ear, 3, fixed shell, 3.1, cover
Shell, 3.2, fixed ring, 4, motor, 4.1, tailing axle, 4.2, shell, 5, fastener.
Specific implementation mode
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
The utility model cover any replacement made in the spirit and scope of the utility model, modification, equivalent method with
And scheme.In order to make the public have thorough understanding to the utility model, in following the preferred embodiment in the utility model specifically
Concrete details is illustrated, and description without these details can also understand that this practicality is new completely for a person skilled in the art
Type.In addition, be not drawn to scale accurately completely for the needs of signal in the attached drawing of the utility model,
This is explained.
As shown in Figure 1, the motor unidirectional damping mechanism of the utility model, including unilateral bearing 1, damping piece 2 and set casing
Body 3, the unilateral bearing 1 are installed on the tailing axle 4.1 of motor 4, and the damping piece 2 is sheathed on unilateral bearing 1, described
Fixed shell 3 encases the damping piece 2, and damping piece 2 is fixed.
The damping piece 2 is rubber pad, includes the rubber sleeve 2.1 coordinated with unilateral bearing 1, and is arranged in the rubber
The locating ring ear 2.2 at 2.1 edge of gum cover.
The fixation shell 3 includes case 3.1 and the fixed ring 3.2 at 3.1 edge of case is arranged, and passes through fastener 5
The fixed ring 3.2 and the locating ring ear 2.2 are fixed on the shell 4.2 of the motor 4.
The unilateral bearing of the utility model is installed on the tailing axle of motor shaft, and the tailing axle with unilateral bearing is inserted in damping piece
In, the damping piece is fixed on the shell of motor by fixed shell and fastener, motor shaft rotation need not damp
Steering when, then motor shaft and the unilateral bearing relatively rotate, i.e., bearing outer ring is substantially motionless because of the damping of damping piece, axis
Inner ring is held then as motor shaft rotates, and not will produce damping action；In another steering, then since unilateral bearing can not turn
It is dynamic, therefore the driving force of motor can generate frictional force between unilateral bearing and damping piece so that motor shaft is being damped
In the case of drive bearing movable, motor shaft is opposite with the unilateral bearing motionless at this time.Lifting is realized to be driven by motor
For device, when rising, unilateral bearing can realize rotation, almost without damping between damping piece, will not increase motor
The power consumption of driving because reversely then there is larger damping, while helping to prevent overload and motor reversal occurs, and declines
When, unilateral bearing can not rotate, therefore can only be rotated with motor shaft, thus larger damping is generated between damping piece at it, have
Conducive to the braking or brake when declining.
It should be noted that, although all there are certain distances between all parts in figure, this is intended merely to view clearly simultaneously
The structure of all parts is presented, but when actual implementation, all parts fit closely, those of ordinary skill in the art can root
It is adjusted according to the introduction of the utility model.
Although embodiment is separately illustrated and is illustrated above, it is related to the common technology in part, in ordinary skill
Personnel apparently, can be replaced and integrate between the embodiments, be related to one of embodiment and the content recorded is not known, then
It can refer to another embodiment on the books.
Only the utility model preferred embodiment is described above, but is not to be construed as the limit to claim
System.The utility model is not only limited to above example, and concrete structure is allowed to vary.In short, all only in the utility model
Various change is within the protection scope of the present utility model made by vertical scope of the claims.
