The invention discloses a limiting type precision gear. The limiting type precision gear comprises a shaft rod, a positioning groove is formed in the surface of the shaft rod, the surface of the shaft rod is sleeved with a gear body, connecting blocks are fixedly connected to the top and the bottom of the front face of the gear body, extrusion frames are arranged on the left side and the right side of the front face of the gear body, vertical plates located on the two sides of the connecting blocks are fixedly connected to the top and the bottom of the extrusion frames correspondingly, balls are slidably connected into the extrusion frames, and the sides, away from the extrusion frames, of the balls extend into the positioning groove and are movably connected with the positioning groove. The balls are placed in the positioning groove and fixed through the extrusion frames, then the extrusion frames and the gear body are connected through bolts and nuts, and the problems that most existing gear limiting modes are matched and limited through one protrusion on the inner side and a groove in the surface of the shaft rod, but the mode does not have the effect of limiting the transverse movement of the gear are solved.
Description
technical field [0001] The invention relates to the technical field of gears, in particular to a position-limited precision gear. Background technique [0002] A gear is a mechanical element with gears on the rim that continuously meshes to transmit motion and power. According to the structure, the gear can be divided into gear teeth, tooth grooves, end faces, legal faces, addendum circles, dedendum circles, base circles, indexing circles, etc. Some of the steels commonly used in the manufacture of gears are quenched and tempered steel, quenched steel, carburized and quenched steel and nitrided steel. Most existing gears are limited by means of a protrusion on the inside and a groove on the surface of the shaft to limit the position, but this method does not have the effect of limiting the lateral movement of the gear, and requires an additional connection structure to The gear is limited. Contents of the invention [0003] In order to solve the problems raised in the ab...
