New-structure transmission coupling

Abstract

The invention discloses a new-structure transmission coupling, comprising: a transmission sleeve and a pin shaft as well as a transmission shaft with a sphere arranged at the end part thereof. A cavity and a shaft hole are arranged in the transmission sleeve, the sphere part of the transmission shaft is located in the cavity, the shaft part is located outside the transmission sleeve, the pin shaftis arranged in the radial direction and the two ends of the pin shaft are respectively inserted into the transmission sleeve and the sphere, one end of the pin shaft is conical, a chute is arranged on the sphere or the transmission sleeve opposite to the conical end in the axial direction, and the conical end is located in the chute and corresponds to the bottom surface of the chute. The new-structure transmission coupling is a universal coupling with large transfer torque, convenient production and processing, hard deformation, long service life and compensable transfer angle.

Description

technical field [0001] The present invention relates to a shaft coupling. Background technique [0002] In the existing industries that use transmission couplings, universal couplings are mainly combined with cross shafts and fork heads to compensate for the angle between shafts and transmit torque, especially in rolling mills in the steel industry, such as Universal joints used in steel rolling mills, high-speed wire rods, bars, plates and other production lines have high bearing torque, but the existing universal joints have short service life, high cost, difficult maintenance and replacement, affect production efficiency, and It is a key component for metallurgical rolling, lifting equipment, transportation machinery and other enterprise equipment.

Problems solved by technology

[0002] In the existing industries that use transmission couplings, universal couplings are mainly composed of cross shafts and fork heads to compensate the angle between shafts and transmit torque, especially in rolling mills in the steel industry, such as Universal couplings used in section steel rolling mills, high-speed wire rods, bars, plates and other production rolling lines have high load-bearing torque, but the existing universal joint shafts have short service life, high cost, difficult maintenance and replacement, affecting production efficiency, and It is a key component for metallurgical rolling steel, lifting equipment, transportation machinery and other enterprise equipment

[0003] 1. The existing universal coupling is mainly composed of two forks and a cross package (cross shaft and bearing). During use, the fork is easily deformed under the action of the transmitted torque. The reason is that The fork is stressed at two points, and the stress concentration is prone to fracture or deformation of the bearing inside.

[0004] 2. In terms of the structure of the existing coupling, the compensation angle is limited

[0005] 3. The currently used universal coupling is difficult to install during assembly, the processing technology is complicated, and the production cycle is long. When the operating speed exceeds 300 rpm, dynamic balancing is required.
