Coupler strong in stability

Abstract

The invention relates to a coupler strong in stability. The coupler strong in stability comprises a copper brake, a buffer spring, connection flanges, a cushion plate, a transition gear sleeve, crowngear sleeves, a positioning sleeve, end caps, a middle shaft, a spring ejection rod and a seal ring, wherein the number of the connection flanges is two, the two connection flanges are coaxially distributed, a connection cavity is formed in the front end face of each connection flange, a positioning cavity is formed in the rear end face of each connection flange, the cushion plate abuts against the bottoms of the connection cavities, the transition gear sleeve and the positioning sleeve are each of a closed ring structure distributed coaxial with the connection cavities, each end cap is embedded in the front end face of each connection cavity and connected with the front end face of each corresponding connection flange through a positioning bolt, and two ends of the middle shaft are respectively connected with the connection flanges. The coupler strong in stability can effectively improve structure strength and bearing cavity and effectively improve convenience and efficiency of connection operation on the one hand, and has good structure toughness and can effectively reduce acting force of axial endplay and radial runout, generated during the power transmission process, on the other hand.

Description

technical field [0001] The invention relates to a shaft coupling, in particular to a shaft coupling for a rolling mill. Background technique [0002] In the operation of the rolling mill equipment, it is necessary to connect the rolling mill and the drive motor equipment through a coupling, which requires relatively large power transmission and high power transmission accuracy. However, in actual use, the current rolling mill does not have a dedicated Couplings, the couplings used are often traditional cross couplings and serpentine couplings. Although they can meet the needs of use, on the one hand, there are insufficient structural strength of the coupling, low power transmission efficiency and power On the other hand, the current couplings are prone to axial movement and radial runout during operation, resulting in serious friction loss of the coupling equipment, and are prone to axial movement, radial runout, etc. The jumping force causes the drive shafts of couplings, ...
