(1) Flange connection Flange connection is to connect the flanges at both ends to other accessories through high-strength bolts and nuts.The connection size and bolt pre-tightening torque of the corresponding accessories.The connecting bolt can only be installed from the flange side of the corresponding fitting, and the nut is pre-tightened from the other side.
(2) End-tooth connection The end-tooth connection is to connect the flanges at both ends to other accessories through the end teeth, high-strength bolts and nuts.The tooth profile size and bolt pre-tightening torque of the corresponding accessories shall be in accordance with its regulations.
(3) Cylindrical shaft hole connection, conical shaft hole oil injection keyless connection, flat head shaft hole connection form and size are specified in the figure.
(4) The size of the oil hole of the tapered shaft hole for oil injection without key connection.
   Note: 1. When frequent loading and unloading is required, an oil-filled keyless connection with an outer taper sleeve can be used.
