Problems solved by technology

In the double-gear staggered-tooth transmission type, regardless of forward or reverse rotation, only one thin-plate gear bears the torque, so the load-carrying capacity is limited, and at the same time, the transmission stiffness is also limited due to the use of elastic elements.
This adjustment method has a complex structure and relatively low requirements for the tooth thickness and pitch of the gear.

Embodiment Construction

[0018] Such as figure 1 As shown, the tooth profile of gear 1 whose pitch circle is cylindrical gradually becomes thicker and thinner from the middle of the tooth length to the end faces of the teeth at both ends, and the pitch circle meshing with gear 1 is the other cylindrical pitch circle. The tooth profile of gear 2 gradually becomes thinner and thicker in the axial direction from the middle of the tooth length to the two end faces of the tooth, and the thickened and thinned ends of the teeth of gear 1 are the same as the thinned and thickened ends of the teeth of gear 2. The ends are meshed to form an adjustable backlash thickening gear transmission pair; through the gap adjustment link in the adjustable backlash thickening gear transmission of the present invention, such as figure 2 The gap-adjusting threaded end caps 11 and 13 shown can adjust the axial relative position between the two gears 1 and 2 of the gear pair to adjust and control the transmission backlash of t...

Abstract

The adjustable side play and variable thickness driving gear pair may be used widely to obtain high transmission precision and high return difference. The driving gear pair is constituted with two gears with parallel axes, columnar reference circle and axial thickness increment, and the side drive play may be controlled through controlling the relative axial position between the gear pair to realize no side play precise driving. The present invention has easy manufacture, high bearing capacity and high transmission precision.

Description

technical field [0001] The invention relates to a gear transmission pair widely used in various industrial fields, especially a gear transmission pair with high requirements on transmission precision and return difference. Background technique [0002] Gear transmission is a widely known transmission method used in various fields of industry. With the development of production technology and the demand for high-quality products, new requirements are put forward for transmission accuracy and backlash, that is, backlash. The control method and technology of the backlash of known gear drive are: 1) variable tooth thickness helical gear transmission, when hobbing and cutting the helical gear on the gear hobbing machine, if the hob both performs the feed motion along the axial direction and also makes a small amount of diameter at the same time To feed, the indexing cylindrical surface of the meshing gear pair is made into a conical surface with a small taper, which can form a va...
