Title:
INTERNAL MESHING BEVEL GEAR TRANSMISSION MECHANISM
Document Type and Number:
WIPO Patent Application WO/2021/248762
Kind Code:
A1
Abstract:
Disclosed is an internal meshing bevel gear transmission mechanism, comprising an internal gear (2) and an external gear (1) that are meshed with each other. The internal gear (2) and the external gear (1) are both bevel gears, a normal tooth profile curve of the external gear (1) is an arc curve (1a), and a normal tooth profile curve (2a) of the internal gear (2) is a cycloid curve (2b), such that the tooth root bending strength and the tooth surface bearing capacity of a transmission gear are improved, root cutting is less prone to occurring, a large transmission ratio can be obtained under the condition of the same size and center distance, sliding abrasion of gear teeth is greatly reduced, and the gear transmission requirements of a high speed, a heavy load and a high power can be successfully met.
