Device of double-shaft air blower for mounting wind wheel

Abstract

The invention provides a device of a double-shaft air blower for mounting a wind wheel, According to the device, the wind wheel is mounted on each armature shaft at two ends of a motor by the double-shaft air blower; the device for mounting the wind wheel and the motor are symmetrically arranged; the device for mounting the wind wheel comprises a pressure delivering mechanism; the pressure delivering mechanism is provided with a pneumatic actuator; the pneumatic actuator comprises two air cylinders, air channels formed by the two air cylinders are connected in parallel after the connection of an air pipe and a conversion adapter; a mechanical valve is mounted on the paralleled air channel; a speed control valve is mounted on each branch air channel; the air cylinders are all provided with air cylinder fixing plates; the air cylinder fixing plates and subplates are fixed together through subplate bolts; two parallel pull rods are vertically arranged between the two air cylinder fixing plates; and the pull rods and the air cylinder fixing plates are in screw thread connection; and spring cushions, flat cushions, and nuts are arranged between the pull rods and the air cylinder fixing plates in sequence. The device has the advantages that the structure is reliable and practicable, the operation is simple and accuracy, the cost performance of the air blower is high, and the repairing and the maintenance are convenient.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an air supply device of an automobile air-conditioning system, in particular to a device for assembling a wind wheel with a double-axis fan. Background technique [0002] With the development of society, the requirements for the degree of automation of electrical equipment are getting higher and higher. Due to their reliable performance and durability, permanent magnet DC motors have been widely used, especially in the field of automobile manufacturing. At present, the number of various types of motors assembled by European and American first-tier manufacturers to a car has exceeded 30, including two-axis fans, which are used as air supply devices for car air-conditioning systems. figure 1 It is a structural diagram of a two-axis fan. The motor is composed of a fixed frame 36, a casing 37, a magnetic tile 38, a front cover 39, an armature subassembly 33 and a bearing 32. The t...

AI Technical Summary

Problems solved by technology

When press-fitting the wind wheel, the tooling is positioned on the outer circle of the casing, and the wind wheel is positioned on the ideal axis of the armature. When the wind wheel is forced into the motor shaft, it will cause: (1). (2) The armature shaft is bent and deformed, and the motor vibrates greatly; (3) The outer wall of the casing is scratched, and the motor is rusted; the performance and appearance of the fan will be substantially damaged

In order to make up for the above defects, it is necessary to increase the processing and assembly requirements of parts, but this will bring about an increase in costs, which is not good for sales
