Description

Technical Field

[0001] This utility model relates to the technical field of motor shafts, and in particular to a mounting structure for the extended shaft of a motor. Background Technology

[0002] The motor shaft is a major component of an electric motor, responsible for transmitting the motor's rotational force to the load. The motor shaft is usually made of high-quality steel or alloy materials, which have high strength and wear resistance. The motor shaft is a key component in the motor that bears and transmits rotational force. Its main function is to transmit the motor's rotational force to the load, and it can also transmit other forces. The extended shaft of the motor usually refers to the extended part of the motor's output shaft.

[0003] In some applications, due to specific usage requirements, the standard motor output shaft length may not be sufficient to connect other devices or transmit greater force. Therefore, it may be necessary to lengthen the motor output shaft. Utility Model Content

[0028] Reference Figure 1-4 This utility model provides a mounting structure for the extended shaft of an electric motor, comprising:

[0029] The main unit 100 includes a motor body 101, an output shaft 102 is provided on one side of the motor body 101, and a connecting shaft 103 is provided on the other side of the output shaft 102. A slot 104 is provided on the surface of the output shaft 102 facing away from the motor body 101.

[0030] The fixing unit 200 includes a connecting cylinder 201 disposed on the surface of the output shaft 102, and a fixing groove 202 opened inside the connecting cylinder 201. One side surface of the connecting cylinder 201 is fixedly connected to the connecting shaft 103, and the inner wall surface of the fixing groove 202 is movably connected to the surface of the output shaft 102. Two sets of threaded rods 204 are inserted and connected inside the connecting cylinder 201, and the surfaces of the threaded rods 204 are movably connected to the output shaft 102. A locking component 208 is disposed on the surface of the threaded rods 204. A round block 205 is fixedly connected to the lower end of each set of threaded rods 204, and a threaded sleeve 206 is threadedly connected to the upper end of each set of threaded rods 204.

[0031] The locking assembly 208 includes a locking rod 208a movably connected to the inner wall surface of the slot 104. One end of the locking rod 208a is fixedly connected to the inner wall surface of the fixing groove 202, and the other end of the locking rod 208a is fixedly connected to a guide block 208b. The surface of the guide block 208b is inclined. The surfaces of two sets of threaded insert rods 204 are movably connected to the locking rod 208a. Inserting the locking rod 208a into the slot 104 and then inserting the threaded insert rods 204 further enhances the connection's firmness.

[0032] Furthermore, a retaining ring 203 is fixedly connected to the side surface of the connecting cylinder 201 opposite to the connecting shaft 103, and the inner wall surface of the retaining ring 203 is movably connected to the output shaft 102. The inner wall surface of the retaining ring 203 has an arc-shaped design. This guides the output shaft 102, making it easier for the output shaft 102 to be inserted into the interior of the retaining groove 202.

[0033] Furthermore, connecting blocks 207 are movably connected to both sides of the fixing groove 202, and the surfaces of the two sets of threaded rods 204 are movably connected to the connecting blocks 207. This limits the movement of the two sets of threaded rods 204.

[0034] Furthermore, a flexible sleeve 209 is fixedly connected to the surface of the retaining ring 203, and the flexible sleeve 209 is made of rubber. The flexible sleeve 209 is movably connected to the surface of the output shaft 102 to increase sealing.

[0035] Furthermore, multiple sets of anti-slip grooves 210 are formed on both sides of the connecting cylinder 201, with each set of anti-slip grooves 210 evenly distributed on the surface of the connecting cylinder 201. This increases the grip friction and facilitates installation.

[0036] During use, the fixing groove 202 is fitted onto the surface of the output shaft 102, so that the surface of the output shaft 102 is movably connected to the inner wall surface of the fixing groove 202. At the same time, the locking rod 208a, which is fixedly connected to the inner wall surface of the fixing groove 202, moves into the interior of the slot 104, thereby making the inner wall surface of the slot 104 tightly fit with the locking rod 208a. Then, two sets of threaded rods 204 are inserted into the interior of the connecting cylinder 201, and the threaded rods 204 are inserted into the interior of the locking rod 208a. Then, the threaded sleeve 206 is twisted to rotate the threaded rods 204 on the surface of the threaded rods 204, so that the threaded rods 204 are locked in the position inside the connecting cylinder 201, which can effectively extend the working distance of the motor body 101.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
