Abstract

The utility model discloses an engagement and disengagement type clutch with a sawtooth-shaped end face. The engagement and disengagement type clutch with the sawtooth-shaped end face comprises a shaft sleeve, an output belt pulley, bearings, a piston and a piston seat. The output belt pulley is supported by one end of the shaft sleeve through the first bearing. A clamp spring and a check ring are installed on the portion, at one side of the first bearing, of the shaft sleeve. A spring base is installed on the side, opposite to the first bearing, of the shaft sleeve. A fixing sawtooth-shaped ring is installed on the output belt pulley. A combined saw-shaped fluted disk is installed on the portion, at one side of the fixing sawtooth-shaped ring, of the shaft sleeve. A reset spring is installed between the combined saw-shaped fluted disk and the spring base. The piston seat is supported by the shaft sleeve through the second bearing. A clamp spring is installed at one side of the second bearing. A baffle is arranged at the other side of the second bearing. The piston is assembled in the piston seat. A seal ring is arranged between the piston and the piston seat. The piston is connected with the fixing saw-shaped fluted disk through the third bearing. The engagement and disengagement type clutch with the sawtooth-shaped end face has the advantages that engagement is free, disengagement is reliable, the carry-over moment is large, heat emission and abrasion of the bearings are reduced due to the check ring, and the service life is prolonged.

Description

A kind of end face zigzag fashion clutch type clutch

Technical field:

The utility model relates to a kind of clutch device, more specifically relates to a kind of and the matching used clutch of power equipment.

Background technique:

At present, the clutch that drives water pump on the suction and cleaning cycle that road environmental protection is used is that traditional interior straight-tooth is realized combination and separated with the mode of outer straight-tooth combination, this clutch needs engine-driving axle to shut down in cohesive process, both sides combination gear must stop operating could be in conjunction with, motor or motor all need to increase starting power, are unfavorable for economizing on resources; In addition, in separation process, also needing stops operating just can separate, and also occurs the problem that causes clutch function to lose efficacy because of separation difficulty, and working life is short.

Model utility content:

For above-mentioned deficiency, the utility model object be to provide a kind of combination freely, separate the end face zigzag fashion clutch type clutch reliable, carry-over moment is large

The utility model is to realize by following technological scheme.

A kind of end face zigzag fashion clutch type clutch, comprise axle sleeve, output belt pulley, bearing, piston and piston seat, output belt pulley by bearings in axle sleeve one end, one side of described bearing is provided with jump ring and back-up ring, the opposite side that bearing is relative is provided with spring seat, and the effect of jump ring, back-up ring and spring seat is spacing; Stationary saw profile of tooth circle is installed on described output belt pulley, and on the axle sleeve of described stationary saw profile of tooth circle one side, cover has in conjunction with saw shape fluted disc, and stationary saw profile of tooth circle is with corresponding in conjunction with the position of saw shape fluted disc, and when work, the two combines; In described combination saw shape fluted disc, return spring is installed, described piston seat is by bearings on axle sleeve, and a side of bearing is provided with jump ring, and opposite side is provided with baffle plate, jump ring is mainly spacing to bearing, and baffle plate is that the two carries out axially locating to piston seat and bearing; In piston seat, be furnished with piston, between piston and piston seat, seal ring be housed, the piston of fit on seal ring and piston seat form hydraulic cylinder motion entirety, thereby drive the motion of miscellaneous part, and described piston is connected with saw shape fluted disc by bearing.

Beneficial effect: end face zigzag fashion clutch type clutch of the present utility model has overcome traditional combination of inner and outside straight tooth-shaped clutch combination, separation difficulty, easily beaten tooth, defect that carry-over moment is little, clutch of the present utility model has combination freely, separation is reliable, carry-over moment is large, the boundary dimension of also having dwindled clutch, has increased its using scope simultaneously; Arranging of back-up ring carried out axial limiting to piston, while guaranteeing both ends of the surface sawtooth transmission work, bearing do not produced to axial force, reduced like this heating and the wearing and tearing of bearing, greatly increased the working life of end face zigzag fashion clutch type clutch.

Accompanying drawing explanation:

The structural representation of Fig. 1 position the present embodiment.

Embodiment:

Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail, but the protection domain of model utility is not limit by embodiment.

See Fig. 1, a kind of end face zigzag fashion clutch type clutch, comprises axle sleeve 1, output belt pulley 5, bearing, piston 12 and piston seat 13; Described output belt pulley 5 is supported and is fixed on axle sleeve 1 by the cylindrical of two clutch shaft bearings 4, axle jump ring 2 is installed on the axle sleeve 1 of clutch shaft bearing 4 one sides and hole back-up ring 3 carries out axially locating, on the axle sleeve 1 of corresponding opposite side, spring seat 6 is installed, carries out spacing; The fixing stationary saw profile of tooth circle 8 of useful hexagon socket head cap screw 7 on output transmission pulley 5, stationary saw profile of tooth circle 8 is positioned at the top of spring seat 6; On the axle sleeve 1 of stationary saw profile of tooth circle 8 one sides, be provided with in conjunction with zigzag fashion dish 10, in conjunction with between zigzag fashion dish 10 and spring seat 6, return spring 9 being installed; Piston seat 13 is supported on axle sleeve 1 the other end by the cylindrical of the second bearing 16, the second bearing 16 two ends are provided with limit stoper, one side shaft of the second bearing 16 puts and shaft block ring 17 is installed that it is carried out to load is spacing, opposite side is spacing by setting up baffle plate 15 to carry out, and baffle plate 15 is fixed on piston seat 13 by countersunk screw; In piston seat 13, be furnished with piston 12, between piston 12 and piston seat 13, seal ring 14 be housed, form like this hydraulic cylinder motion entirety; Piston seat 13 with link together by the 3rd bearing 11 in conjunction with zigzag fashion dish 10, the cylindrical of the 3rd bearing 11 supports this piston 12, inner circle is supported in conjunction with on saw shape fluted disc 10.

When work, cylinder moving drives piston 12 in motion, thereby piston 12 promote the 3rd bearing 11 move drive move on axle sleeve 1 in conjunction with zigzag fashion dish 10, and compression retracteding position spring 9 is to combining with stationary saw shaped ring gear 8 in conjunction with saw shape fluted disc 10, thereby drive output transmission pulley 5 to rotate, realize service behaviour needs.
