Technical field
The present invention relates to a kind of elastic component, refer to that especially a kind of axle head pad that cooperates is used for the elastic component that motor end play is adjusted.
Background technology
At present, regulating motor end play can realize by nonelastic control and two kinds of methods of flexible control.
Nonelastic control, as shown in Figure 4, be to regulate motor end play by the axle head pad of different-thickness size, its shortcoming is: need some by the different axle head pad of thickness specification, because the classification of thickness specification directly determines end play to adjust precision, assembling needs the preliminary examination of cooperation end play to select the axle head pad of different size again; Number of spare parts is many, the precision height, and assembling is complicated, the cost height; Because of nonelastic compensation, axially still have gap among a small circle, and cause the wearing and tearing of axle head pad with motor operation, the gap can increase, thus motor still has axial endplay to cause motor operation noise when moving thus.
Flexible control includes with the steel wavy spring and compensates axle head pad control axial endplay, as shown in Figure 5; But its element precision height, different coefficient of elasticity requires the part of different size, needs suitable heat treatment to guarantee corresponding elastic demand, and part stability is difficult for guaranteeing that part elasticity keeps shock-resistant number of times low; Also include in addition with rubber parts and make elastic component compensation axle head pad control axial endplay, as shown in Figure 6, material is NBR (nitrile rubber), and structure is cylindrical or annular, and its cross section is rectangle or circle; But material NBR elastic performance is poor, and is not ageing-resistant, the life-span deficiency; The elasticity of annular (circular cross-section) structure is nonlinear change, is unfavorable for axially moving the stationarity that play changes; Cylindrical and annular (cross section is a rectangle) is because of there being local sharp edge, produces stress easily and concentrate and cause broken invalid when being hit.
Summary of the invention
Because the deficiency of above-mentioned existing elastic component, the technical problem that solve is: provide a kind of simple in structure, elasticity keep the life-span long, realize the big elastic component of compensation range.
For solving the problems of the technologies described above, the invention provides a kind of elastic component that motor end play is adjusted that is used for, pad is located at the drive of motor the tip of the axis, one end is against the motor inwall, the other end is against the axle head pad that is sheathed on the motor transmission shaft, described elastic component and motor inwall against an end face and with the axle head pad against the other end be the plane, and the side that connects both ends of the surface on the described elastic component is an arc surface;
Described elastic component is circular or patty;
It is described that to be used for the elastic component that motor end play adjusts made by silicon rubber.
Of the present invention to be used for the elastic component size that motor end play adjusts little, realizes that compensation range is big, can realize not having the gap assembling, and simple in structure being easy to quantizes to produce; The suitable use of its material is beneficial to it and is used in different environment, and high-and low-temperature resistance is ageing-resistant, and elasticity keeps the life-span long; Under same size, select the different hardness of elastomeric material, can realize different elastic performance requirements; In addition, utilize its rational cross section structure, make elastic type linear change of the present invention, can make the play of axle steadily reduce noise because of axial force changes.

Embodiment
A kind of elastic component that motor end play is adjusted that is used for of the present invention is a kind of elastomeric element, can compensate the gap that produces because of assembling in the scope of certain force, refers to that especially a kind of axle head pad that cooperates is used for the elastomeric element that motor end play is adjusted; The circular elastic component 10 of first preferred embodiment of the present invention as shown in Figure 1, its pad is located at the drive of motor the tip of the axis, wherein, one end face 12 is against the motor inwall, other end 11 is against the axle head pad that is sheathed on the motor transmission shaft, the both ends of the surface 11,12 of described elastic component 10 are the plane, and its side 13 that connects both ends of the surface is an arc surface; Similarly, the elastic component 10 ' of the second preferred embodiment patty of the present invention as shown in Figure 2, its end face 12 ' that contacts with the motor inwall is the plane, the other end 11 ' that contact with the axle head pad is the plane also, and its side 13 ' is an arc surface; In addition, a kind of elastic component that is used for the adjustment of motor end play of the present invention is made by silicon rubber, utilizes the different hardness of rubber material under same size, can realize different coefficient of elasticity demands.
The described elastic component that is used for the adjustment of motor end play can be used with the axle head pad of a cap shape, as shown in Figure 3, described circular elastic component 10 can be sheathed on the axle head jut 21 of axle head pad 20 of a cap shape and be used, axle head pad 20 centers of cap shape offer a passage 22, and the power transmission shaft of power supply machine inserts used; When drive of motor through-drive, axle head jut 21 is main stress point, because of it has born most of power, thereby avoids elastic component 10 pressurizeds to overrun and distortion excessively; Simultaneously, elastic component 10 is sheathed on the axle head jut 21, the power that is delivered on the axle head jut 21 is cushioned, and the gap that compensation produces because of assembling in the scope of certain force, and the gap that produces because of the loss of axle head jut 21 of compensation.
As shown in Figure 7, the elastomeric products physiology of straight line 30 expression elastic components is thought the state of linear change, and it is stressed steadily, but is perfect condition, can't realize in the reality; The elastic component 10,10 ' that is used for the adjustment of motor end play of the present invention, it is the end face 11,12,11 ', 12 ' on plane, and the connection end face is the side 13,13 ' of arc surface, so cross section structure makes its elasticity produce the class linear change of representing as curve 40, make axial force change and tend to be steady, thereby reduce the noise that the play because of axle causes; As if existing elastic component as shown in Figure 6, the cross section is circular, and then its elasticity is nonlinear change curve 50, and is not steady thereby the axial force of axle changes, and the axle play has noise strongly.
