Problems solved by technology

In actual use, there are small swing angles and movement interference, resulting in damage to the roll shaft head and the flat hole end of the coupling and serious wear of the drum gear shaft of the reducer, which even leads to cracking of the base and shell of the reducer, resulting in premature failure of the bearings and rolls of the rolling mill. wear, which greatly shortens the life of couplings, reducers and rolling equipment

Abstract

The invention discloses a coupling. The coupling comprises a spline shaft. One end of the spline shaft is externally connected with a rolling mill through separate type double crowned teeth, and the other end of the spline shaft is connected with a speed reducer through a cardan joint. According to the coupling, the separate type double crowned teeth and the cardan joint are adopted; the tilt angle is increased; the eccentricity compensation ability is improved; and meanwhile, an inner gear shaft sleeve which is likely to be damaged is easy to dismount, replace and maintain.

Description

technical field [0001] The invention relates to a shaft coupling, which belongs to the technical field of mechanical transmission. Background technique [0002] In the production line of steel mills, the commonly used parts connecting rolling machinery and reducers are GSL telescopic drum gear couplings, which play the roles of transmitting torque, adjusting misalignment, and shock absorption. At present, the GSL coupling produced by JB / T10540-2005 standard is generally used, one end (flat hole end) is connected to the flat shaft of the rolling mill, and the other end (internal gear sleeve) is connected to the gear shaft of the reducer. In actual use, there are small swing angles and motion interference, resulting in damage to the roll shaft head and the flat hole end of the coupling and serious wear of the drum gear shaft of the reducer, which even leads to cracking of the base and shell of the reducer, resulting in premature failure of the bearings and rolls of the rolling...
