Gear clutch with high meshing success probability

Abstract

The invention provides a gear clutch with the high meshing success probability. A section of inclined face is manufactured on the side, close to a non-torque-transmission gear face, of the gear tooth end face of a movable sleeve gear and the gear tooth end face of a static sleeve gear, a straight face is reserved on the side close to a torque-transmission gear face, and the width of the inclined face accounts for about 95% of the gear thickness. The inclination direction of the movable sleeve tooth end face slope is opposite to the moving direction of the movable sleeve teeth, the inclination direction of the static sleeve tooth end face slopes is the same as the moving direction of the movable sleeve teeth, and the inclination angles of the tooth end face slopes of the movable sleeve teeth and the static sleeve teeth are equal. During meshing, the movable sleeve teeth move downwards to the static sleeve teeth under the action of an external force, the inclined faces of the tooth end faces of the movable sleeve teeth and the inclined faces of the tooth end faces of the static sleeve teeth make contact with each other, and along with rotation of the movable sleeve teeth, due to the action of the inclined faces, the movable sleeve teeth generate an axial movement distance L relative to the static sleeve teeth; when the gear teeth of the movable sleeve gear rotate over the current static sleeve gear tooth in contact with the gear teeth and are in contact with the working tooth surface of the next static sleeve gear tooth, the distance L can avoid the tooth collision phenomenon, the probability of one-time meshing success of the sleeve gear is improved, and the torque transmission strength of the sleeve gear is kept not to be reduced.

Description

technical field [0001] The invention relates to a tooth type clutch with a high probability of successful meshing, and a tooth end structure for improving the probability of successful meshing of this type of clutch. Background technique [0002] At present, the torsion transmission teeth of the known tooth clutches generally adopt involute tooth shape, and the pressure angle of the tooth shape is generally 15°-35°. Due to the existence of the pressure angle, the tooth clutch has the ability of automatic centering, and the involute tooth The tooth shape is basically the same as the processing technology of the gear teeth, and the processing is very convenient. Therefore, the tooth clutch with the involute tooth shape is widely used compared with the tooth shape of the involute tooth shape. The tooth clutch produces tooth side clearance by reducing the tooth thickness, which facilitates the axial meshing of the torque transmission sleeve teeth. In order to ensure the bending...

Problems solved by technology

[0003] The purpose of the present invention is to provide a tooth clutch that overcomes the disadvantages of the existing tooth clutches that use spiral motion to mesh teeth, relying on tooth thickness reduction to form a limited backlash, and a low probability of successful meshing (5%-10%). A tooth clutch with a high probability of successful meshing, which can increase the probability of successful clutch meshing to more than 80% without reducing the bending and shearing strength of the teeth of the torque transmission sleeve
