High-performance crowned tooth coupler

Abstract

The invention discloses a high-performance crowned tooth coupler which comprises a driving end inner tooth ring, a driving end outer tooth shaft sleeve, a gear pair connecting the driving end inner tooth ring with the driving end outer tooth shaft sleeve, a driven end inner tooth ring, a driven end outer tooth shaft sleeve, and a gear pair connecting the driven end inner tooth ring with the driven end outer tooth shaft sleeve. The high-performance crowned tooth coupler further comprises combination pressing covers at the two ends, seals, and a connecting structure of a driving end and a driven end, wherein pressure angle alpha between the driving end inner tooth ring and the driving end outer tooth shaft sleeve is 20-30 degrees; and pressure angle alpha between the driven end inner tooth ring and the driven end outer tooth shaft sleeve is 20-30 degrees. With the adoption of the scheme, the carrying capacity of the high-performance crowned tooth coupler is improved, the service life is prolonged, and the production cost is reduced. In addition, the driving end inner tooth ring and the driven end inner tooth ring can be exchanged completely, so that the inventory cost of spare parts is reduced. Furthermore, the quick-worn seals of can be replaced online, so that the maintenance downtime is shortened, and the maintenance labor intensity is reduced.

Description

technical field [0001] The invention relates to a drum-shaped gear coupling, which can be widely used in the connection between a motor and a reducer, between a motor and equipment, and between a reducer and equipment. Background technique [0002] The drum gear coupling is an important mechanical basic component. Its function is to connect the driving shaft and the driven shaft, and transmit torque to make the two shafts rotate together. In engineering use, due to manufacturing and installation errors, deformation and wear of parts, subsidence of the foundation, etc., the axis position of the two axes will deviate, and axial displacement, radial displacement, angular displacement and comprehensive displacement will occur. The existence of offset causes additional dynamic loads on shafts, bearings, and couplings, causing vibrations and deteriorating the working conditions of machine parts. Among the various types of couplings, the drum-shaped gear coupling has the advantage...

Problems solved by technology

[0004] The disadvantages of the existing drum-shaped gear couplings are: 1. The existing drum-shaped gear couplings fail to conduct in-depth research on the motion mechanism of the transmission parts. , The parameters such as the pressure angle, addendum height coefficient, dedendum height coefficient, and displacement circle radius of the internal gear ring at the driving end and the internal gear ring at the driven end are unreasonable, resulting in low load-carrying capacity and low working life of the product; 2. The inner ring gear at the driving end and the inner ring gear at the driven end adopt convex-convex (concave-convex) spigot positioning, and the inner ring gear at the driving end and the inner ring gear at the driven end are not interchangeable, which increases the cost of spare parts; 3. The gland is integrated In this way, it is impossible to replace the seals of wearing parts online. Sometimes, the outer gear sleeve needs to be removed before replacement, which increases the workload of inspection and maintenance, affects the production efficiency of the rolling mill, and increases the labor intensity of maintenance.
