Description

Technical Field

[0001] The utility model relates to the technical field of axial measurement of blower motors, in particular to axial clearance measuring equipment for blower motors. Background Art

[0002] Usually, the blower on the car is a centrifugal blower. The working principle of the centrifugal blower is similar to that of the centrifugal ventilator, except that the air compression process is usually carried out through several working impellers (or stages) under the action of centrifugal force. The blower has a high-speed rotating rotor. The blades on the rotor drive the air to move at high speed. The centrifugal force makes the air flow along the involute in the involute-shaped casing to the blower outlet. The high-speed airflow has a certain wind pressure, thereby achieving the replenishment of fresh air. The shaft end clearance of the blower motor is an important factor in determining the motor noise. During the production process, the shaft end clearance needs to be measured to determine whether the product is qualified.

[0003] The existing blower motor axial clearance measurement equipment has the following disadvantages: currently, manual measurement with a dial indicator is used, which has problems such as high measurement difficulty and poor reliability. It is not suitable for mass production. Therefore, we propose a new blower motor axial clearance measurement equipment. Utility Model Content
