Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] To achieve the above object, the technical scheme of the present invention is as follows:

[0028] see Figure 1-4 As shown, the present invention provides an air-cooled waterproof eccentric air motor. The motor includes a motor body 1 and a rotating shaft 2. The motor body 1 is drivingly connected to the rotating shaft 2. The rotating shaft 2 is provided with a bearing installation position 21, and the An air passage 22 is arranged inside the rotating shaft 2 , and the air passage 22 communicates with the bearing installation position 21 .

[0029] In this example, the air passage 22 is a...

Abstract

The invention discloses an air-cooled waterproof eccentric pneumatic motor, belongs to the technical field of motors, and particularly relates to the air-cooled waterproof eccentric pneumatic motor. The motor comprises a motor main body and a rotating shaft, the motor main body is in driving connection with the rotating shaft, a bearing mounting position is arranged on the rotating shaft, an air duct is arranged in the rotating shaft, and the air duct is communicated with the bearing mounting position. Compared with the prior art, firstly, the air duct is arranged in the rotating shaft of themotor, so that compressed air can be introduced into a bearing through the air duct, the internal pressure of the bearing is far greater than the external pressure, and dust and water are prevented from entering the bearing; secondly, when the compressed air is blown out from the interior of the bearing, heat of the bearing can be taken away, and the effect of cooling the bearing is achieved; andfinally, the motor is simple in structure, low in cost and convenient to use and popularize.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to an air-cooled waterproof eccentric air motor. Background technique [0002] Pneumatic flat sander is widely used in product polishing. However, in the case of wet sanding, water and dust will enter the bearing of the sand blasting machine motor, which will seriously affect the service life of the motor. During the use of the sand blasting machine, the motor will be frequently repaired and replaced, which greatly increases the cost of the sand blasting machine. [0003] The prior art discloses an air motor with the patent number CN201821329057.6. The motor includes a motor connected with a waterproof connection line. The motor is fixedly mounted on a waterproof motor composed of a waterproof motor upper cover and a waterproof motor lower cover. In the casing, a waterproof sealing ring is pressed between the waterproof motor upper cover and the waterproof motor lower cover. The wa...
