The dry cutch comprises a clutch wheel, a slipping body, a pressing disc, a separate lever, a separate bearing, separation claws and a separation claw seat, wherein the wheel-rim outer surface of the clutch wheel is provided with a belt groove, the inner surface thereof is a conical surface, the slipping body is a wheel with conical surface and can slide axially, the pressing disc is fixed on a shaft, an adjusting bolt passes through the slipping body and the pressing disc, a disengaging spring is arranged between the slipping body and the pressing disc, the separable lever is arranged on the pressing disc, the separation claws are slidably matched with the shaft, the separation claw seat is fixed on a bearing seat of a power take-off shaft, and a convex and concave co-operating structure capable of axially and relatively moving exists between the separation claws and the separation claw seat. The utility model has the positive effects that the clutch has an integral structure, the joint effect is excellent, the transmitting torque is large, and the clutch is not influenced by rotary speed and environment, the structure is simple, the spare parts are fewer, the assembly is easy, and no wear-prone elements are used.

Description

Coaxial-type friction wheel dry clutch

Technical field

The utility model belongs to mechanical field, is specifically related to drive clutch.

Background technique

At present, being used for mechanically operated clutch, though kind is many, all is the branch body structure basically, complex structure, component are many, and assembling, repair demolition are more loaded down with trivial details, some friction plate clutchs, driving torque is smaller, in conjunction with weak effect, only is suitable for the transmission of power under the high commentaries on classics condition.Power transfer member is immersed in the wet clutch in the oil, expends the high-quality oil plant, and working environment is strict, and common environment uses down and has potential safety hazard.

Summary of the invention

The purpose of this utility model provides a kind of coaxial-type friction wheel dry clutch, overcomes that existing minute body structure zero clutch parts are many, carry-over moment is little and wet clutch expends oil plant, and operating conditions requires harsh shortcoming.

Clutch of the present utility model is slided rub body, platen by clutch pinion, separator levers, release bearing, disengaging pawl, and the disengaging pawl seat is formed.The shape of each member and combination relation are that clutch pinion has belt grooves for the wheel rim outer surface, and internal surface is the conical surface of outer end diameter greater than the inner end, and clutch pinion is installed in the power input shaft front end by the thrust-bearing of cylindrical bearing in the axis hole and axle head.The sliding body that rubs is the wheel that conical surface is arranged, and the internal conical surface of its conical surface and clutch pinion matches.Be distributed with circular hole on the sliding body end face that rubs.The sliding body that rubs is installed on the power input shaft or axle sleeve of external splines, can endwisely slip.Platen is the disk that is distributed with the axle bed of circular hole and separator levers on the end face.Circular hole on the platen is corresponding with circular hole on the sliding body that rubs.Platen is fixed on the power input shaft.Pass sliding rub body and platen with the adjusting bolt.Platen and the sliding dress support release spring between the body that rubs.Separator levers is installed on the axle bed on the platen, and an end of lever is clipped in to be regulated between bolt nut and the platen, and the other end of lever is near release bearing.Release bearing is installed on the disengaging pawl by inner ring, bearing face pressure holding separator levers.Disengaging pawl has control arm, and disengaging pawl is slidingly matched with axle.The disengaging pawl seat is fixed on the bearing support of pto, protruding, the recessed cooperating structure for can axially relatively moving between disengaging pawl and the disengaging pawl seat.Clutch is in normally off, stirs the disengaging pawl control arm, then becomes separated state.

Good effect of the present utility model is: clutch is an overall structure, in conjunction with effective, transmitting torque is big.Be suitable for all kinds of machinery, be not subjected to the influence of rotating speed and environment.Simple structure, few, the simple and convenient assembly of component.No easily damaged parts, few safeguard, few maintenance, make, user cost is low.

Description of drawings

Accompanying drawing is looked sectional view for the utility model master.

Embodiment

Provide embodiment of the present utility model below in conjunction with accompanying drawing.

Making as shown in drawings clutch pinion 1, the sliding body 2 that rubs, cylindrical outer surface with material, the technology of prior art has spline, endoporus to have the cunning of the keyway body that rubs that axle sleeve 12, platen 4 are installed.Power input shaft 9 is processed the clutch pinion Bearing Installation neck of stairstepping, sliding axon cover and the platen installation neck of rubbing.Disengaging pawl 10 is made the stepped cylinder of outer cylinder surface, and an end of minor diameter is installed release bearing 6, and a large diameter end has the control arm that fuses, and there is axial double wedge the end.Disengaging pawl seat 7 makes ring dish seam and bearing support is mounted to whole structure, bores the bolt hole that fixes with the power input shaft bearing support, the groove that shaft sleeve part separately matches with the disengaging pawl raised line on the ring dish.One end of release bearing 6 outer rings is made the end face to axis direction shown in the drawings.Make disengaging pawl cover 11 shown in the drawings with material for sliding bearing.Earlier disengaging pawl cover 11 is contained on the axle, pushes disengaging pawl seat 8 again, fixedly separated pawl seat on the power input shaft bearing support.Release bearing 6 is engaged on the disengaging pawl 10, again disengaging pawl 10 is contained on the axle sleeve 11.Separator levers 5 as shown in drawings is installed on platen 4.Fixed platen 4 on axle, and the sliding body spline housing 12 that rubs is loaded onto the sliding body 2 that rubs then, will regulate bolt 3 by penetrating the cunning body that rubs behind the forward direction, pass platen 4 again, with nut with the separator levers end clips between nut and platen.Release spring is installed in the spring seat of sliding rub body and platen, and the pressure of Regulation spring.By cylindrical bearing 14 clutch pinion 1 is installed on the axle journal, clutch pinion is adorned thrust-bearing 15 outward, and thrust-bearing is adorned thrust metal 16 outward, adds the locking screw of screwing on behind the back-up ring 17, promptly finishes embodiment of the present utility model.
