Spindle refers to the shaft that receives power from the engine or motor and transmits it to other parts. The main axis, also known as the "optical axis", is the abbreviation of the "main optical axis": the diameter with symmetry in the optical set. For example, the main axis of a spherical mirror is a straight line perpendicular to the mirror surface through the center of the mirror surface. The main axis of the lens or optical axis optical device group is the connecting line of the center of each mirror surface.

The main shaft is equipped with a rotating part of the fan, which is used to transmit torque to make the impeller rotate. The main function of the main shaft is to transmit torque. The main shaft, together with other parts of the bearing and rotor part, becomes the main shaft part, mainly the rotor part of the machine. Different main shaft parts have different functions. For example, the steam turbine mainly absorbs steam energy to drive the generator set to generate electricity. The super organic main shaft drives the piston to output power, and the main shaft of the water pump drives the impeller to produce pressure to transport water and other media.

Spindle is a typical shaft part, which is one of the key parts of the equipment. It transfers the whirling motion and torque to the equipment through the end of the spindle. Therefore, the spindle must bear the torque and bending moment in the work, and also requires a high rotation accuracy. Therefore, the manufacturing quality of the spindle will directly affect the service life of the whole equipment. The spindle part drawing specifies a series of technical requirements, such as dimensional accuracy, shape and position tolerance, surface roughness, contact accuracy and heat treatment requirements. These are to ensure that the spindle has high rotary accuracy and stiffness, good wear resistance and dimensional stability.

Chengdu Haihe Power Equipment Accessories Industrial Co., Ltd. was established in 2002, formerly known as Chengdu Feixuan Ventilating Machinery Development Co., Ltd.
