Abstract
The utility model relates to a clutch non-return device, in particular to a clutch non-return device for a washing machine. The clutch non-return device for the washing machine comprises a shifting fork component, a pawl, a ratchet, a belt pulley, a clutch sleeve, a ratchet embracing spring, a cover plate, a shell, a No.205 bearing, a shaft assembly and a No.105 one-way bearing, wherein the pawl on the shifting fork component is connected with the ratchet, and the belt pulley is connected with the ratchet embracing spring and the shaft assembly through the clutch sleeve; the lower end of the shaft assembly is fixed with an inner ring of the No.105 one-way bearing in an interference fit mode, and an outer ring of the No.105 one-way bearing is fixed with the shell in the interference fit mode; and the upper end of the shaft assembly is in clearance fit with an inner ring of the No.205 bearing, and an outer ring of the No.205 bearing is fixed with the cover plate in the interference fit mode. The device can eliminate the conditions for producing the running-in and wear in the original non-return device, and can ensure that a clutch has relatively durable performance in the aspect of a non-return function.
Description
Technical field
The utility model relates to a kind of clutch backstop, specifically is used for the washing machine clutch backstop.
Background technology
The backstop of the clutch of use in washing machine is in the laundry machine dehydration process at present; Because the friction that produces between brake disc external diameter and the non-return spring internal diameter; Under condition of boundary lubrication; Make brake disc external diameter and non-return spring internal diameter produce break-in, wearing and tearing gradually, finally cause the clutch backstop to lose efficacy.Using now " non-return spring " is about 2000 times as general its fault-free life-span of clutch of backstop, and tame standard A level product requirement is the requirement greater than 5000 times, the conventional device A level requirement that generally can not be up to state standards.
Summary of the invention
The purpose of the utility model is that a kind of novel clutch backstop will be provided, thereby eliminates the condition that produces break-in, wearing and tearing in the former backstop, makes the clutch backstop durable in use.In order to realize above-mentioned purpose, the utility model is to take following technical scheme to realize:
The clutch coupling of washing machine backstop; Comprise that pull-fork assembly, ratchet, ratchet, belt pulley, clutch cover, ratchet embrace spring, cover plate, 205 bearings and axle assembly; Also comprise 105 unilateral bearings, the ratchet on the described pull-fork assembly is connected with ratchet, and belt pulley embraces spring through clutch cover with ratchet and axle assembly is connected; The lower end of axle assembly and 105 unilateral bearing inner ring interference fit are fixed, and the outer ring of 105 unilateral bearings and housing interference fit are fixed; Axle assembly upper end and 205 bearing cone matched in clearance, the outer ring of 205 bearings and cover plate interference fit are fixed.
These utility model improvements are; Substitute prior art with 105 unilateral bearings and use common 105 bearings; Original non-return spring and auxiliary equipment are got rid of; Do not change the geometric parameter of other parts of clutch, make full use of the non-return characteristic of 105 unilateral bearings and the geometric parameter intercommunication characteristic of this bearing and former common 105 bearings.Though the just simple components replacement of this utility model can eliminate the condition that produces break-in, wearing and tearing in the former backstop, and 105 unilateral bearings can be born the life-span 5,000 times, can guarantee the more lasting in non-return function aspects performance of clutch.
Description of drawings
Fig. 1 is the structural representation of existing clutch backstop.
Fig. 2 is the structural representation of clutch backstop of the present invention.
The specific embodiment
As shown in Figure 1, what prior art was used is common 105 bearings 71.
The utility model scheme; As shown in Figure 2; The clutch coupling of washing machine backstop comprises that pull-fork assembly 1, ratchet 2, ratchet 5, belt pulley 3, clutch cover 4, ratchet embrace spring 6, cover plate 9, housing 8,205 bearings 10 and axle assembly 11; Also comprise 105 unilateral bearings 7, the ratchet 2 on the described pull-fork assembly 1 is connected with ratchet 5, and belt pulley 3 embraces spring 6 through clutch cover 4 and ratchet and axle assembly 11 is connected; The lower end of axle assembly 11 and 105 unilateral bearings, 7 inner ring interference fit are fixed, and the outer ring of 105 unilateral bearings 7 and housing 8 interference fit are fixed; Axle assembly 11 upper ends and 205 bearings, 10 inner ring matched in clearance, the outer ring of 205 bearings 10 and cover plate 9 interference fit are fixed.
Ratchet 2 on pull-fork assembly 1 disengages with ratchet 5, and 3 torque suspensions of belt pulley are embraced spring 6 through clutch cover 4 and ratchet and are passed to axle assembly 11.The lower end of axle assembly 11 and 105 unilateral bearings, 7 inner ring interference fit are fixed, and the outer ring of 105 unilateral bearings 7 and housing 8 interference fit are fixed; Axle assembly 11 upper ends and 205 bearings, 10 inner ring matched in clearance, the outer ring of 205 bearings 10 and cover plate 9 interference fit are fixed.Because 105 unilateral bearings, 7 outer rings are fixing by housing 8, and inner ring can only unidirectionally rotate.As shown in Figure 2 seeing from top to bottom can only clockwise direction be rotated, counterclockwise can not rotate, so axle assembly 11 under the restriction of 105 unilateral bearings, can only clockwise unidirectional rotation.In the laundry machine dehydration running, 11 torque suspensions of clutch shaft assembly are passed to dehydrating vessel in washing machine, and the moisture on the washing clothes is thrown out of under centrifugal action in the dehydrating vessel in washing machine thereby make.In this dehydrating operation process, 105 unilateral bearings 7 not with other any part generation break-in, wearing and tearing, thereby guarantee the permanent reliability service of clutch backstop.
