Abstract

The invention discloses a kind of reduction box, including motor, reductor and positive coupling, the positive coupling is set in the periphery of the output shaft of motor and the input shaft of reductor so that motor and speed reducer is connected, and the one end of positive coupling away from motor is provided with oil sealing.The present invention connects motor and speed reducer by a positive coupling, and oil sealing is set in one end of positive coupling, avoids the phenomenon generation that lubricating oil enters motor internal;The motor that fell only is needed during maintenance, dismounting motor can easily dismantles oil sealing, and need not put lubricating oil totally in maintenance.

Description

A kind of reduction box
Technical field
The present invention relates to a kind of reduction box.
Background technology
At present, the reduction box of in the market is referred to as reductor or decelerator again, is to connect reduction box according to prime mover, subtracts Fast case reconnects the principle of working machine come what is be operated, is a kind of power transmitting apparatus, can be divided into industrial reduction box and vapour Use reduction box.Existing reduction box product is using gear or tooth axle on motor shaft.
But there is following defect in existing deceleration box technology:
(1) when electric engine oil seal damages, motor internal can be caused to be full of the phenomenon of lubricating oil;
(2) need lubricating oil added by casing to put totally when repairing, and dismantle whole reduction box, it is very troublesome.
The content of the invention
For overcome the deficiencies in the prior art, it is an object of the invention to provide a kind of reduction box, and it can reduce electricity The probability of machine oil-feed, it is easy to maintenance.
The purpose of the present invention adopts the following technical scheme that realization:
A kind of reduction box, including motor, reductor and positive coupling, the positive coupling are set in the output shaft of motor So that motor and speed reducer is connected, the one end of positive coupling away from motor is provided with oil for periphery with the input shaft of reductor Envelope.
Further, the input shaft of the reductor is bevel gear shaft.
Further, the input shaft of the reductor is gear.
Further, the outer ring of the cross section of positive coupling is circle.
Further, the outer ring of the cross section of positive coupling is hexagon.
Further, the outer ring of the cross section of positive coupling is quadrangle.
Further, the inside of positive coupling is straight-through keyway.
Further, the inside of positive coupling is the spline and keyway of mutual UNICOM.
Further, the equal length of the output shaft of the length of the input shaft of the reductor in positive coupling and motor.
Compared with prior art, the beneficial effects of the present invention are:
(1) present invention connects motor and speed reducer by a positive coupling, and oil is set in one end of positive coupling Envelope, avoid the phenomenon generation that lubricating oil enters motor internal;
(2) when repairing, it is only necessary to fell motor, and dismounting motor can easily dismantles oil sealing, and in maintenance not Need to put lubricating oil totally.
Brief description of the drawings
Fig. 1 is a kind of sectional view of reduction box of the present invention.
In figure, 1, motor;2nd, reductor;3rd, positive coupling;4th, the output shaft of motor;5th, the input shaft of reductor;6、 Oil sealing.
Embodiment
Below, with reference to accompanying drawing and embodiment, the present invention is described further, it is necessary to which explanation is, not Under the premise of afoul, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination Example.
As shown in figure 1, the present invention provides a kind of reduction box, it includes motor 1, reductor 2 and positive coupling 3, motor 1 It is prior art with reductor 2, of the invention theing improvement is that adds the positive coupling 3, and positive coupling 3 has In light weight, ultralow inertia and highly sensitive superior function, and in actual applications, positive coupling 3 has non-maintaining, superpower Oil resistant and corrosion resistant advantage.The structure of positive coupling 3 is simple, cheap, brings cost low using positive coupling 3 Advantage.
In the present invention, positive coupling 3 is set in the periphery of the output shaft 4 of motor and the input shaft 5 of reductor so that electricity Machine 1 and reductor 2 are connected, that is, equivalent to one connector of positive coupling 3, connect the output shaft 4 of motor and subtract The input shaft 5 of fast machine, the one end of positive coupling 3 away from motor 1 are provided with oil sealing 6.
Motor 1 provides power, exports to reductor 2, is outputed power by reductor 2, motor 1 and reductor 2 are direct Passing power is connected by positive coupling 3.The input shaft 5 of reductor can be bevel gear shaft, or gear etc..
The outer ring of the cross section of positive coupling 3 is circular, hexagon or quadrangle, the internal junction of positive coupling 3 Structure is straight-through keyway or one section of paragraph key groove UNICOM of spline one.The input shaft 5 and electricity of the reductor coordinated with positive coupling 3 The size of the output shaft 4 of machine is identical with length, avoid because section difference cause transmitted power to be mutated the problem of, realize and its Coordinate two part equal strength.
Above-mentioned embodiment is only the preferred embodiment of the present invention, it is impossible to the scope of protection of the invention is limited with this, The change and replacement for any unsubstantiality that those skilled in the art is done on the basis of the present invention belong to institute of the present invention Claimed scope.
