Generally, the tapered shaft end is threaded, and the coupling is fixed on the shaft with a nut. The TⅢ output shaft of the HG5-251-79 frame is matched with the shaft head of the agitator. The end of the output shaft is a special shaft head with a tapered front end and a threaded rear part, which is matched with the tapered hole and the internal thread of the shaft head of the agitator.

The utility model discloses a tapered coupling, which comprises a cylindrical main body, connecting teeth are arranged on the outer wall of the main body, and connected left and right end holes and tapered holes are arranged in the main body; A circlip and a gasket are arranged in sequence in the left end hole, and a bolt with a limit disc penetrating the circlip, the gasket and the main body is arranged in the main body, the limiting disk is pushed on the inner side of the gasket. The patented technology of the utility model has the advantages of simple structure, convenient operation and low cost. It can be connected and disassembled quickly, preventing the occurrence of damage during the disassembly process. At the same time, due to the tapered hole, it can realize automatic docking, Improve production efficiency.

The new coupling realizes the torque transmission between the non-standard shaft with taper. It includes a second shaft sleeve matched with a common transmission shaft and a first shaft sleeve matched with a tapered shaft. The first shaft sleeve at the front end and the second shaft sleeve at the rear end are fixedly connected. The part of the tapered shaft that matches the first shaft sleeve includes at least a threaded part and a tapered part at the front end of the threaded part.

Coupling shaft taper connection:

The gear and the shaft are connected by keys; the bearing and the shaft are installed by matching; where the bearing is not connected with the steel plate, it is also installed by matching with the outer sleeve. The inner and outer rings of the bearing should be fixed at both ends.. It can be directly connected to the inner hole of the gear through the key, or through the coupling when the requirement is not high, and it can be connected by the key through the shaft sleeve.

coupling taper hole machining:

1:10 taper = (large diameter of shaft hole-small diameter of shaft hole): length of shaft hole

When grinding the inner hole of the taper hole, pull the grinding head at an angle of 1:10 and check the hole with small shaft diameter with a template gauge. The holes with large shaft diameter are actually matched with the real object of the shaft coated with red Dan.
