Abstract
The utility model discloses an improved structure of a friction wafer type clutch, which is mainly composed of a sleeve barrel of a speed reducing tooth, a pressure spring, a pressure spline sleeve, a helical spline, a friction wafer, a spline sleeve barrel and a driving tooth shaft, wherein the spline sleeve barrel is sheathed on the driving tooth shaft; the pressure spline sleeve is sheathed with the spline sleeve barrel; the pressure spline sleeve is clamped with the spline sleeve barrel through rotating the spline; the friction wafer is sheathed with the pressure spline sleeve. The utility model is added with the pressure spline sleeve, and the friction wafer is sheathed with the pressure spline sleeve; therefore, in the process that the driving tooth shaft moves forwards in the axial direction, the friction wafer does not move forwards following the driving tooth shaft and the driving tooth shaft is difficult to deflect and swing. Besides, in the utility model, both ends of the spline sleeve barrel are sheathed with bearings; the spline sleeve barrel is connected with a bearing seat through the bearings so the driving tooth shaft which is sheathed in the spline sleeve barrel can not deflect, and the stability is good.
Description
Technical field
The utility model relates to a kind of clutch, particularly relates to a kind of improvement structure of friction plate clutch.
Background technique
The friction plate clutch of commonly using (as shown in Figure 1) comprises friction plate sleeve 1 ', spring 2 ', compresses spline housing 3 ', friction plate 4 ' and driving gear axle 5 '.Friction plate sleeve 1 ' compresses spline housing 3 ' by friction plate 4 ' drive when the external force driven rotary; Compress spline housing 3 ' and drive driving gear axle 5 ' rotation, pressing friction sheet 4 ' under the spiral thrust of helical spline on the other hand by helical spline on the one hand; Driving gear axle 5 ' and friction plate 4 ' move axially under shift fork power F effect simultaneously.When driving gear axle 5 ' is under the anti-band of external force when surmounting state, compress spline housing 3 ' and under the effect of reverse acting spiral power, unclamp friction plate, realize the cltuch slipping function.The clutch of this structure is in driving gear axle 5 ' easy beat in advancing moving process vertically, the less stable of driving gear axle 5 '.
The model utility content
The purpose of this utility model is to provide a kind of improvement structure of friction plate clutch of good stability.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of improvement structure of friction plate clutch, it mainly by deceleration tooth sleeve, holddown spring, compress spline housing, helical spline, friction plate, splined sleeve, driving gear axle and form; Described splined sleeve is socketed on the driving gear axle; Compress spline housing and be socketed on the splined sleeve, compress between spline housing and the splined sleeve by the rotation spline and be connected together; Described friction plate is made of a plurality of big friction plates and a plurality of friction sheet, and a plurality of big friction plates and a plurality of friction sheet are provided with at interval, mutually against, the friction sheet is socketed in and compresses on the spline housing, its endoporus with compress the spline housing rubbing contact; Described deceleration tooth sleeve has the step hole of coaxial setting, and its aperture is rotating to be socketed on the splined sleeve, and its macropore is socketed in the outer rim of friction plate, forms rubbing contact with big friction plate outer rim, contacts with big friction plate outer rim by the macropore inwall; Described holddown spring is socketed on the splined sleeve and end face leans and compressing an end of spline housing.
The utility model also comprises two bearings, and these two bearings are socketed in the two ends of splined sleeve respectively.
Described splined sleeve is connected with the driving gear axle by internal spline.
The utility model also comprises O shape circle, and it is socketed on the driving gear axle and is arranged on splined sleeve and axially the leaning between the face of driving gear axle.
After adopting such scheme, because the utility model has increased by one and has compressed spline housing, friction plate is socketed in this compresses on the spline housing, move forward vertically in the process at the driving gear axle, friction plate does not move forward with the driving gear axle, the driving gear axle is difficult for beat, and the utility model also at the two ends of splined sleeve socket bearing, is connected with bearing support by bearing, make the driving gear axle that is nested with in splined sleeve beat can not take place, stability is better.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
