Abstract
The utility model discloses a unilateral friction clutch for a belt wheel. The unilateral friction clutch comprises a transmission shaft, wherein the belt wheel is fixedly mounted on the transmission shaft; a friction plate is in sliding fit with the rear side of the belt wheel; a spring baffle is fixedly arranged on the rear side of the friction plate; a spring is padded between the front end of the spring baffle and the friction plate; and a jackscrew cover is arranged at the front end of the belt wheel in a covering way. The unilateral friction clutch solves the technical problem that a transmission part of machinery equipment can automatically clutch the belt wheel under a serious load, and the purpose that the belt wheel automatically clutches the transmission shaft under the load state so as to protect a motor and the machinery equipment is lastly achieved.
Description
Technical field
The utility model technology relates to a kind of clutch, and a kind of belt pulley clutch particularly, this belt pulley clutch can effectively prevent due to load infringement that motor and machinery equipment are brought, the long service life that extends machine.
Background technique
Belt pulley transmission at present is the important form as mechanical drive mode.Existing belt pulley does not often possess the function of automatic clutch.To such an extent as to can't clutch pulley under the serious load of machinery equipment cause the damage of motor and the equipment of motor.Overcoming above drawback is present urgent problem.
The model utility content
The purpose of this utility model is to provide the monolateral friction clutch of a kind of belt wheel; solve the machinery equipment drive part under serious load; technical problem that can automatic clutch pulley realizes that finally under load condition, belt pulley automatic clutch transmission shaft is with the purpose of protection motor and machinery equipment.
For achieving the above object, solution of the present utility model is:
The monolateral friction clutch of belt wheel includes transmission shaft, is installed with belt pulley on transmission shaft, the friction plate that the belt pulley rear side is slidably matched, the friction plate rear side is fixed with spring stop, is equipped with spring between the front end of spring stop and friction plate, and the front end of belt pulley is covered with the jackscrew lid.
The front end of described transmission shaft is fixed with overhead in the axle sleeve back-up ring of belt pulley sidewall.
The monolateral friction clutch of belt wheel mainly comprises two-part: 1. belt pulley part mainly contains belt pulley, the supercentral belt wheel axle sleeve of belt pulley, axle sleeve back-up ring and spindle nose jackscrew and jackscrew lid.2. the friction clutch part, mainly contain screw, spring and spring stop and set screw nut be housed on the friction plate friction plate.Have spline on friction plate and spring stop, cooperatively interact with splined shaft.Splined shaft passes the belt wheel axle sleeve, is fixed by the spindle nose jackscrew.In actual use, when load was excessive, friction plate and belt pulley skidded, and realized separating of belt pulley and transmission shaft, reached the purpose of protection motor and machinery equipment.
Description of drawings
Fig. 1 is the utility model pulley structure schematic diagram.
As shown in the figure, the parts label is: 1. jackscrew covers 2. spindle nose jackscrew 3. axle sleeve back-up ring 4. belt wheel axle sleeve 5. belt pulley 6. friction plate screw 7. friction plate 8. spring 9. spring stop 10. friction plate nut 11. transmission shafts.
Embodiment
Referring to accompanying drawing, the monolateral friction clutch of belt wheel, include transmission shaft 11, be installed with belt pulley 5 on transmission shaft 11, the friction plate 7 that belt pulley 5 rear sides are slidably matched, friction plate 7 rear sides are fixed with spring stop 9, are equipped with spring 8 between the front end of spring stop 9 and friction plate 7, the front end of belt pulley 5 is covered with jackscrew lid 1, and the front end of transmission shaft is fixed with overhead in the axle sleeve back-up ring 3 of belt pulley sidewall.
Working procedure and principle:
The monolateral friction clutch of belt wheel is arranged on the transmission shaft of machinery equipment, with spindle nose jackscrew 2, belt wheel is compressed, regulate friction plate nut 10 and make friction plate 7 and belt pulley 5 close contacts.Install the vee belt, open motor, belt pulley 5 normal operations.When serious load, belt pulley 5 begins to skid with friction plate 7, realizes the clutch of belt pulley 5 and transmission shaft 11, has protected motor and machinery equipment.Extended the working life of equipment.
Claims (2)
1. the monolateral friction clutch of belt wheel, include transmission shaft, it is characterized in that: be installed with belt pulley on transmission shaft, the friction plate that the belt pulley rear side is slidably matched, the friction plate rear side is fixed with spring stop, be equipped with spring between the front end of spring stop and friction plate, the front end of belt pulley is covered with the jackscrew lid.
