Description
Technical Field
The utility model relates to the technical field of motors, in particular to a motor fan dismounting tool.
Background
In the high-speed rotation process of the motor, the motor shaft drives the fan to rotate, so that the motor is cooled. If the fan is not installed in place, the conditions of fan looseness, positioning key deformation, large vibration and the like can occur in the running process of the motor, so that the connection reliability of the shaft and the fan is very important. The design of the motor is that the shaft extension end is connected with the fan through a key, which is a common structure, and the contact surface of the shaft extension end and the fan usually has a cylindrical surface (as shown in figure 1) and a conical surface (as shown in figure 2).
The installation process of the fan is generally as follows: a positioning key is arranged in a key groove at the shaft extension end, and after the heated fan base is sleeved into the shaft extension end, an axial fixing block or a round nut and the like are arranged for axial positioning.
In the structure of circular conical surface contact, one side is by fan seat and circular conical shaft face cooperation, and the opposite side is by round nut locking to this carries out axial fixity to the fan, through the circular conical surface cooperation, has increased area of contact, is favorable to axial positioning. But also increased the degree of difficulty of fan installation simultaneously, if the fan is not enough with axle complex pretension, the fan sleeve axle is installed not in place, can lead to axial positioning insecure on the contrary.
At present, a fan is installed by sleeving the fan on a shaft after being heated, tightly knocking the fan by a rubber hammer by a master worker, visually observing whether a fan seat is tightly attached to a shaft shoulder or not, wherein the condition that the fan seat is tightly attached to the shaft shoulder indicates that the installation position of the fan is correct, and screwing a round nut for fastening. When the fan needs to be disassembled during motor maintenance, after the round nut is screwed out, the fan seat is knocked by a rubber hammer in the opposite direction, so that the fan is withdrawn from the shaft extension stop.
However, the above-described mounting method is not reliable in mounting the fan on the conical contact surface because it is difficult to visually check whether the fan is mounted in place because there is no distinct shoulder.
