Description

Universal jaw one-way clutch Technical Field The utility model belongs to the field of clutches, and particularly relates to a jaw clutch. Background The jaw clutch generally comprises a pair of jaw discs, two end shaft sleeves, a pressure spring and other components, wherein the two end shaft sleeves are in mechanical engagement for transmitting power, the two end shaft sleeves are respectively connected with a driving shaft and a driven shaft, the function of transmitting power is realized through the jaw discs, clutch teeth on the jaw discs are mutually embedded or separated to achieve the clutch of the driving shaft and the driven shaft, and the saw-tooth clutch teeth have larger axial component force when reversing, push away the jaw discs and skid, so that the jaw clutch is commonly used for a jaw unidirectional clutch. Compared with a roller type one-way clutch, the jaw type one-way clutch can bear higher torque and rotating speed, can realize faster slipping and unloading and higher slipping frequency, and has the advantages that axial component force of clutch teeth is correspondingly increased when in overload, so that a jaw disc is pushed open to slip, and the function of a safety clutch is realized. The clutch teeth of the two jaw plates are in surface contact, the friction pair is low, the friction force is large, the contact surface of the clutch teeth has moderate pressure angle, the pressure angle is large, the axial component force is large, the power transmission performance is reduced, the pressure angle is small, the axial component force is small, the friction force is difficult to overcome, the sliding difficulty is reduced, the separation reliability is reduced, the power transmission performance and the separation reliability are contradicted, overload slip can play a role in overload protection on parts to be protected, but the overload slip can possibly cause ‌ transmission failure and other part damage, the starting load and the starting frequency of the overload slip are limited, the structure also has high requirements on the parallelism of a driving shaft and a driven shaft due to the fact that lateral torque is formed due to insufficient parallelism of the driving shaft and the driving shaft, the lateral offset load is caused, and the parallelism of the driving shaft and the driven shaft is high. When the pressure spring pretightening force is disassembled and adjusted, the corresponding spanner and pipe tongs are matched, the corresponding flat square wrench and pipe tongs are arranged on the parts for clamping, the occupied space is large, and the structure is complex. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provide the universal jaw one-way clutch which can realize reliable power transmission and separation and can effectively buffer and eccentrically drive. The technical scheme is that the universal jaw unidirectional clutch comprises an outer sleeve, an elastic corrugated pipe, an upper shaft sleeve, an upper jaw plate, a lower jaw plate, a handle and a lower shaft sleeve, wherein external threads at the upper end of the lower shaft sleeve are sleeved on screw holes at the lower end of the outer sleeve, stepped holes at the upper end of the lower shaft sleeve are sleeved on the lower end of the lower jaw plate and fixedly connected with each other, clutch teeth at the upper end of the lower jaw plate are attached to a jaw pin of the upper jaw plate, the lower end of the upper jaw plate is sleeved on an inner hole of the lower jaw plate, the upper end of the upper jaw plate is fixedly connected with the lower end of the elastic corrugated pipe, the upper end of the elastic corrugated pipe is fixedly connected with the lower end of the upper shaft sleeve, the upper side of the upper shaft sleeve is positioned in an inner hole at the upper side of the outer sleeve, spherical surface of the lower side of the upper shaft sleeve is attached to an inner circular arc chamfer of the inner hole of the outer sleeve, and the handle is respectively inserted into an installation hole A of the lower shaft sleeve and an installation hole B of the outer sleeve.
