Detailed Description
In order to make the technical solutions and advantages of the present invention clearer, the following will describe embodiments of the present invention in further detail with reference to the accompanying drawings.
An embodiment of the present invention provides an electric motor, as shown in fig. 1. The motor includes: the device comprises a motor belt pulley 1, a motor shaft 2, a shaft sleeve 3, a fastener 4 and a connecting key 5;
wherein the motor pulley 1 comprises: the cross sections of the first belt pulley 11 and the second belt pulley 12 are semicircular rings, and the first belt pulley 11 and the second belt pulley 12 can be combined into a hollow cylindrical structure;
motor belt pulley 1 parcel is on axle sleeve 3, and motor belt pulley 1 passes through fastener 4 and is connected with axle sleeve 3 location, and axle sleeve 3 parcel is at the surface of motor shaft 2, and axle sleeve 3 is connected with motor shaft 2 through connection key 5, and fastener 4 passes behind motor belt pulley 1 and the axle sleeve 3 and contacts with the surface contact of motor shaft 2, can separate belt pulley 1 and axle sleeve 3 through back-out fastener 4.
The motor provided by the embodiment of the invention can be used in the scene that the motor belt pulley needs to be replaced in the production process of an oil pumping well and a screw pump well. When the motor belt pulley 1 needs to be replaced, all the fasteners 4 used for fastening the hollow cylindrical structure and the shaft sleeve 3 are screwed out, so that the hollow cylindrical structure is separated from the shaft sleeve 3, the first belt pulley 11 and the second belt pulley 12 forming the hollow cylindrical structure are separated, and then the first belt pulley 11 and the second belt pulley 12 of other sizes are connected with the shaft sleeve 3 in a positioning mode through the fasteners 4.
Therefore, the motor belt pulley 1 with the split structure is provided, and the motor belt pulley 1 is installed on the motor through the fastener 4, so that the motor belt pulleys with different sizes can be replaced in a screwing-out and screwing-in mode of the fastener 4, the motor belt pulley 1 is convenient to disassemble and good in safety performance, is suitable for replacing the motor belt pulleys with any sizes, can shorten the time for replacing the motor belt pulley 1, and effectively improves the working efficiency.
In addition, the motor shaft 2 is wrapped by the shaft sleeve 3, so that the motor shaft 2 can be protected, and the motor shaft 2 is prevented from being damaged when the motor belt pulley 1 is replaced.
Compared with the mode of using a pulley extractor tool to disassemble the motor belt pulley 1 and using a hammer and other tools to install the motor belt pulley 1, the accident that the claw of the pulley extractor flies out to hurt people due to uneven stress of three claws on the pulley extractor when the motor belt pulley 1 is disassembled is avoided, the situations that the pulley extractor cannot be used when the gap between the motor belt pulley 1 and a bearing gland is too small and the size of the motor belt pulley 1 is larger are avoided, and the situation that the motor is damaged due to overlarge impact force caused by using the hammer and other tools when the motor belt pulley 1 is installed is also avoided.
It should be noted that, during the installation of the motor pulley, the length of the fastening member 4 is not fixed, but only required to be ensured to have a length meeting the requirement. For example, the fastening member 4 may pass through the outermost motor pulley of the motor and through the bushing to contact the innermost motor shaft 2 of the motor, and the fastening member 4 may press against the motor shaft 2 to fixedly connect the motor pulley 1 and the bushing 3, that is, the fastening member 4 may pass through the motor pulley 1 and the bushing 3 to contact the outer surface of the motor shaft 2.

Illustratively, as shown in fig. 2, the fastener 4 is a hexagon socket single head bolt.
In addition, in order to accommodate the fastening member 4, as shown in fig. 1, the first pulley 11 is provided with internally threaded through holes, wherein the number of the internally threaded through holes may be any value not less than 1. Illustratively, the first pulley 11 is provided with 2 internally threaded through holes, that is, the first pulley 11 is connected with the shaft sleeve 3 by 2 fasteners 4 in a positioning manner, and the 2 internally threaded through holes are provided with internal threads matched with the external threads of the fasteners 4.
Similarly, the second pulley 12 is also provided with female screw through holes, and the number of the female screw through holes may be any value not less than 1. Exemplarily, the second pulley 12 is also provided with 2 internal threaded through holes, that is, the second pulley 12 is also connected to the bushing 3 by 2 fasteners 4, and the 2 internal threaded through holes have internal threads adapted to the external threads of the fasteners 4.
