Description

Technical Field

[0001] This utility model relates to the field of motor shaft technology, specifically to a motor shaft. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is represented by the letter M (formerly D in the old standard) in circuit diagrams. Its main function is to generate driving torque, serving as a power source for electrical appliances or various machines. A generator, represented by the letter G in circuit diagrams, primarily converts mechanical energy into electrical energy. Currently, the most common method is to use heat energy, water energy, etc., to drive the generator rotor to generate electricity. When discussing electric motors, the use of a motor shaft is involved. An existing patent, patent publication number CN111917232A, discloses a motor shaft... A hollow structure is provided axially at at least one end of the device. A coolant pumping mechanism with spiral grooves is located near the shaft end of the hollow structure, allowing coolant to enter the hollow structure due to the suction generated by the rotation of the motor shaft. The spiral grooves are located on the inner surface of an annular component, which is fixedly mounted to the hollow structure, or the spiral grooves are directly located on the inner surface of the hollow structure. Several sets of coolant channels are provided radially along the motor shaft, communicating with the hollow structure. When the motor shaft rotates, coolant is flung out of the hollow structure through the coolant channels to cool the internal components of the motor housing. In this invention, by providing a hollow structure and a coolant pumping mechanism, a pump-like structure is formed. When the motor shaft rotates, coolant can be drawn into the hollow structure and then flung out through the coolant channels, achieving cooling and lubrication of the internal components of the motor housing and improving the motor's heat dissipation capacity.

[0003] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: in practical applications, it is inconvenient to adjust and position them, which also makes it inconvenient to connect and fix the motor shaft to the transmission components, affecting the normal use of the motor shaft. Therefore, we propose a motor shaft to solve the above-mentioned problems. Utility Model Content

[0031] The adjusting assembly 3 includes a rotating rod 300 inserted at one end of the crossbar 1. A square bar 301 is fixedly installed on the surface of the rotating rod 300. A rod hole for inserting the rotating rod 300 is opened on one side of the crossbar 1. An annular groove is opened on the surface of the crossbar 1. A bolt 302 is inserted into the inner wall of the annular groove. One end of the bolt 302 is threadedly connected to the surface of the square bar 301.

[0032] The positioning and mounting assembly 4 includes a positioning rod 400 fixedly mounted on one end of the rotating rod 300. A positioning hole is provided on one side of the positioning rod 400, and a limiting rod 401 is inserted into the inner wall of the positioning hole. One end of the limiting rod 401 passes through the positioning rod 400 and extends to the outside of the positioning rod 400. A bolt rod 402 is threadedly connected inside the positioning hole. A hexagonal limiting hole is provided on one side of the bolt rod 402, and a hexagonal reinforcing ring 403 is fixedly installed inside the hexagonal limiting hole. The adjustment assembly 3 and the positioning and mounting assembly 4 facilitate the adjustment of the length of the motor shaft during use, and also facilitate the connection and positioning of the motor shaft with the transmission components. This makes it easier to install and adjust the motor shaft during use, thus improving the ease of use of the motor shaft.

[0033] See Figure 1A groove is provided on one side of the mounting rod 200, and a screw 203 is inserted into the groove. One end of the screw 203 passes through the mounting rod 200 and extends into the interior of the mounting rod 200 to be threadedly connected to the surface of the hexagonal rod 201. Both the surface of the mounting rod 200 and the surface of the hexagonal rod 201 are provided with threaded holes for the screw 203 to be threaded. The screw 203 facilitates the positioning and installation of the hexagonal rod 201 during use, thereby maintaining the installation stability of the hexagonal rod 201.

[0034] See Figure 6 A rubber block 204 is fixedly installed on one side of the insertion hole on the mounting rod 200. One side of the rubber block 204 fits against one side of the hexagonal rod 201. The inner wall of the insertion hole is slidably connected to the surface of the hexagonal rod 201, and the hexagonal rod 201 is adapted to the insertion hole. The rubber block 204 is provided to provide buffer protection for one end of the hexagonal rod 201 during use, thus maintaining the installation stability of the hexagonal rod 201.

[0035] See Figure 6 An insertion strip 205 is fixedly installed on the inner wall of the insertion hole on the mounting rod 200. The surface of the hexagonal rod 201 is provided with an insertion groove for the insertion strip 205 to pass through, and the inner wall of the insertion groove is slidably connected to the surface of the insertion strip 205.

The inner wall of the limiting hole is slidably connected to the surface of the limiting rod 401. Through the limiting rod 401 and the limiting hole, the positioning and installation of the transmission components are convenient during use, and the stability of the component installation and positioning is maintained.

[0038] See Figure 2 The limiting rod 401 has a hemispherical end inside the positioning hole, and the bolt rod 402 has a rounded end. By setting the limiting rod 401 to a hemispherical end and the bolt rod 402 to a rounded end, during the tightening of the bolt rod 402, the rounded end of the bolt rod 402 presses against the hemispherical end of the limiting rod 401, thereby causing the limiting rod 401 to move outward, so that the other end of the limiting rod 401 presses against the inner wall of the transmission component, thus facilitating its positioning and installation.

[0039] During operation, when the motor shaft length needs to be adjusted according to usage requirements, loosen bolt 302, then separate one end of bolt 302 from the surface of square bar 301, and then pull the rotating rod 300 to its position inside the crossbar 1. After the overall length of the motor shaft is adjusted to the appropriate length, tighten bolt 302, and then install the motor shaft inside the motor. When it is necessary to install the transmission component, place the transmission component on the surface of positioning rod 400, and then tighten bolt rod 402. Bolt rod 402 presses against one end of limiting rod 401, so that one end of limiting rod 401 is pressed by bolt rod 402 and pressed and positioned against the inner hole of the transmission component, thereby increasing its installation stability.
