Abstract
The utility model relates to an improved motor head of a tubular motor. The motor head comprises a motor and a cooperating shaft of a subsequent assembly; and a motor output shaft is connected with the cooperating shaft. A blind hole is arranged at the center of the motor output shaft; and a straight slot is arranged at the side wall of the blind hole. The cooperating shaft is sleeved at the motor output shaft; a line-styled key is arranged at the inner wall of the cooperating shaft and cooperates with the straight slot of the motor output shaft. An elastic element is installed inside the blind hole; and a silencer sleeve is installed between the outer wall of the motor output shaft and the inner wall of the cooperating shaft. The provided motor head the advantages: the line-styled key at the inner wall of the cooperating shaft is one part of the cooperation shaft, so that the dislocation and movement can be prevented and thus wearing of the two ends of a bolt due to the movement of the bolt at the radial direction can be avoided; close fit between the motor output shaft and the cooperating shaft is ensured because of the elastic element and a buffer function on the vibration at the axial direction can be realized; and the silencer sleeve plays a good role in reduction of vibration of the motor output shaft at the radial direction, thereby effectively reducing noises during the tubular motor running.
Description
Technical field
The present invention relates to the accessory on tube shaped electric machine, especially a kind of improved electric head of tube shaped electric machine.
Background technology
The motor head of existing tube shaped electric machine adopts spline to be connected with brake assemblies (claiming again clutch) thereafter conventionally, spline fitted mesh degree is high, but between the output shaft of motor and the power shaft of brake assemblies for being rigidly connected, lack flexibility, during due to machine operation, can produce lasting vibration, vibration can reduce the tightness of spline fitted for a long time, make spline fitted bad, output shaft due to motor is main moment output point again, therefore, in the bad life-span that can reduce tube shaped electric machine of spline fitted degree, easily produce the problem such as get stuck.
For addressing the above problem, described in patent No. CN201220496111.2 " manually tube shaped electric machine ", its lower clutch cover is located on motor output shaft, there is a blind hole at place, lower clutch axle center, and offers elongate slots on the relevant position of interior car ratio, and a latch is installed on the output shaft of motor, mounted latch embeds in elongate slots, and can be along elongate slots axial motion, the front end of latch is provided with a spring, plays the effect of damping.Motor header structure in this patent has played certain damping effect, and spring makes lower clutch be connected with motor output shaft elasticity with elongate slots structure, make up the poor fit that motor oscillating causes, reduced the failure rate of motor head part, extended the useful life of tube shaped electric machine.
But this structure is Shortcomings part still, because latch embeds in elongate slots, latch upwards can move freely in the footpath of motor output shaft.Therefore,, when machine operation, can wear and tear in the two ends of latch on the inwall of lower clutch; The second, this spring can reduce motor head output shaft axially on vibration, but motor shaft vibration diametrically will be directly passed to lower clutch, and cause tube shaped electric machine vibration.For the motor of high speed rotating, the shake that motor output shaft footpath makes progress is the main source of tube shaped electric machine vibration, therefore, when motor shaft exists slight curves, can cause tube shaped electric machine body vibration, produces drone noise.
Summary of the invention
The utility model is for the deficiencies in the prior art, a kind of motor head of novel tube shaped electric machine is provided, vibration is upwards all reduced in axial and footpath at motor output shaft effectively, noise while reducing the work of tube shaped electric machine, and be that motor output shaft and subsequent components closely cooperate, improve the useful life of tube shaped electric machine.
The technical scheme in the invention for solving the above technical problem is: a kind of improved electric head of tube shaped electric machine, the fitted shaft that comprises motor and subsequent components, motor output shaft is connected with fitted shaft, it is characterized in that: motor output shaft center has a blind hole, and have a straight trough on the sidewall of blind hole; Fitted shaft is socketed on motor output shaft, and fitted shaft inwall has a keyboard, and the straight trough on a keyboard and motor output shaft coordinates; Flexible member is installed in blind hole, and between the outer wall of motor output shaft and the inwall of fitted shaft, noise reduction cover is installed.
Described flexible member is spring or resilient rubbber cushion.
Described noise reduction cover is O type rubber ring.
Compared with prior art, the invention has the advantages that: a keyboard of fitted shaft inwall is the part in fitted shaft, can not produce dislocation and mobile, avoided latch moving and cause the wearing and tearing at latch two ends diametrically; Flexible member has guaranteed to coordinate closely between motor output shaft and fitted shaft, and the vibration is axially played to cushioning effect, and noise reduction cover to motor output shaft vibration diametrically played good damping effect, avoided vibration to be transferred in the subsequent components of tube shaped electric machine, the noise while effectively reducing tube shaped electric machine operation.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
Tube shaped electric machine has comprised motor, brake assemblies, decelerator, travel switch and journey controller.Motor is connected with subsequent components by motor output shaft, transmits torque to subsequent components, drives the overcoat of tube shaped electric machine to rotate.
Shown in Fig. 1 and Fig. 2, motor is comprised of output shaft 1, oiliness bearing 5, front stall 4, rotor 6, stator 7, back seat 8.Oiliness bearing 5 respectively has one in front stall and back seat, and rotor is arranged on output shaft, and rotor and stator coordinate makes electric machine rotation, and by output shaft 1 output torque.
On output shaft 1, there is blind hole 11, in blind hole, for elastic elements 3, on the sidewall of blind hole, have a straight trough.Described flexible member is spring or elastic rubber ring.
Fitted shaft 9 is inputs of subsequent components, and described subsequent components is brake assemblies or decelerator.Fitted shaft 9 is socketed on motor output shaft, and fitted shaft inwall has a keyboard, and the straight trough on a keyboard and motor output shaft coordinates.And noise reduction cover 2 is installed between the outer wall of motor output shaft 1 and the inwall of fitted shaft 9.
Described noise reduction cover 2 is O type rubber ring.
The output shaft of motor and fitted shaft have elastic component 3 in the axial direction as buffering, and noise reduction cover is installed diametrically, and vibration is radially cushioned.The vibration producing while making electric machine rotation can not be delivered in subsequent components, reduces vibration and the noise of tube shaped electric machine.Its latch of the mix proportion of one keyboard and straight trough coordinates more firm.
