Reinforced structure for gear and rotating shaft connection

Abstract

The invention provides a reinforced structure for gear and rotating shaft connection. The structure comprises a gear, a flat key, a rotating shaft, a reinforcing column, an adjusting hole and buckles;the rotating shaft is fixedly arranged on the inner side of the gear, second springs are fixedly connected to one side faces of the two buckles, a movable cavity is formed in the periphery of the rotating shaft, the reinforcing column is fixedly connected to the middle of each support block, arc clamping grooves are formed in the two sides of the top of the reinforcing column, first springs are fixedly connected to the left end and the right end of the support block, and a screw is fixedly connected to the upper portion of a convex connecting block. Accordingly, by means of cooperation of thereinforcing column and the fixed cavity, when the gear rotates at a high speed, the reinforcing column can be thrown out of the rotating shaft by means of centrifugal force, then the reinforcing column is fixed through the fixed cavity so that the joint of the gear and the rotating shaft can be reinforced through the reinforcing column, and axial support is provided; meanwhile, the radial load ofthe flat key is shared, the phenomena of cutting, deforming and cracking of the flat key are reduced, and the stability and accuracy of the gear in the high-speed rotating process are enhanced.

Description

technical field [0001] The present invention relates to the technical field of the connection structure between a gear and a rotating shaft, and more specifically relates to a reinforcement structure for connecting a gear and a rotating shaft. Background technique [0002] Gears are divided into sliding gears and fixed gears according to the connection mode. For the connection of fixed gears, the connection between the gears and the rotating shaft in the prior art is usually connected by a flat key connection, and the flat key connection has neutrality. Good, high positioning accuracy, easy disassembly and assembly, etc., but the flat key cannot bear the axial load, and the gear and the shaft are only connected by a single flat key in some high-speed, high-load occasions, so the flat key is prone to appear after long-term use Shearing, deformation, cracking, etc. will affect the connection and transmission accuracy of the gear and the shaft. [0003] Based on the above inve...
