Internal spherical gear and external spherical gear

Abstract

The invention discloses an internal spherical gear and an external spherical gear in the figure 1, and relates to high load of a tanning drum, low torque of a spur gear, high starting load and damaged gear shape. An internal spherical tooth consists of a horizontal shaft middle peripheral internal R semiarc and two end surface bearing holes. An external spherical tooth consists of a fan ring large arc middle connected vertical shaft cylinder lower end surface and a vertical shaft cylinder upper end surface connected circular ball. Two shaft shoulders are matched with two end surface bearing holes, a gear ring base shaft hole and the horizontal shaft middle peripheral internal R semiarc to combine as an internal spherical line. A fan ring parallel surface is matched with a large gear ring base groove and a section to combine as a fan ring arch circle. A large gear base in the figure 1 replaces a drum disc skeleton to increase the torque of the external spherical gear to solve low torque of the spur gear, high starting load and damaged gear shape. The external spherical tooth drives the internal spherical tooth to slide and rotate in the same direction to solve hard friction and easy wear between teeth, and long service life. The internal and external spherical teeth are replaced, and large and small gear ring bases are not replaced to save the production cost. The internal and external spherical gears are applied to rotary transmission of tanning machinery.

AI Technical Summary

Problems solved by technology

[0002] At present, the domestic tanning machinery (drum) equipment uses medium-sized and large-scale spur gear transmission, and the large-scale production equipment (drum) of tanning machinery has a maximum loading capacity of more than 80 tons of fur (including chemical raw material aqueous solution). 1. The rotational transmission torque of the passive spur gear is small, and the active and passive spur gears increase the torque, but because the passive large spur gear of the existing drum body is installed on the outer end surface of the drum body (disc skeleton), it is larger than the diameter of the passive large spur gear (circle (disc skeleton) is installed on the outer end surface of the drum body, resulting in the limited torque of the passive large spur gear of the drum body, and can only rely on the coupling to assist in starting the heavy-duty rotating (drum) equipment, so the tanning machinery (drum) is active, Passive spur gears have a large starting and operating load, the teeth are not strong enough to be easily deformed and damaged, and the production and use time is short. The maximum spur gear diameter of tanning machinery (drum) equipment is more than Φ4500 mm, which is inconvenient for heat treatment and quenching
