Description

Technical Field

[0001] The utility model belongs to the technical field of pulleys and relates to a novel motor wheel. Background Art

[0002] An electric motor (commonly known as a "motor") is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The motor system includes a control device, an electric motor, a driven device, a transmission device, and a pipe network load, etc. It is a complex system involving multiple disciplines, multiple professions, and multiple fields. The transmission device is an important part of the motor, and the transmission device is generally divided into gear transmission and pulley transmission. For pulley transmission, the assembly of the pulley generally requires the use of a hammer to knock it into the motor shaft. When the knocking force is too large, it is easy to cause damage to the motor shaft or the pulley, thereby increasing the cost of use. At the same time, the required disassembly requires the pulley to be lifted out, so employees are required to have a certain amount of strength and skills, resulting in low loading and unloading efficiency.

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1As shown, the novel motor wheel comprises a wheel body 1 and a motor shaft 2 connected to the wheel body 1, and a loading and unloading assembly is arranged between the motor shaft 2 and the wheel body 1 for facilitating the loading and unloading of the wheel body 1. The loading and unloading assembly consists of a mounting unit for mounting the wheel body 1 and a moving unit arranged on the motor shaft 2 and cooperating with the mounting unit and controlling the axial movement of the wheel body 1. The mounting unit is an assembly sleeve 3 which is sleeved on the motor shaft 2 and connected thereto. The wheel body 1 is sleeved on the assembly sleeve 3 and connected thereto. The left end of the assembly sleeve 3 extends outside the wheel body 1, and the right end of the assembly sleeve 3 is located inside the wheel body 1, and of course, it can also extend outside the wheel body 1. The outer peripheral wall of the assembly sleeve 3 located outside the wheel body 1 is provided with a radially outward protrusion which conflicts with the wheel body 1. The contact ring 4 is connected to the wheel body 1 through a plurality of studs, and a connecting ring 5 which protrudes radially outward and is connected to the contact ring 4 is arranged on the outer peripheral wall of the motor shaft 2 located at the assembly sleeve 3. The connecting ring 5 is also connected to the contact ring 4 through the studs. At the same time, the connecting ring 5 is used to prevent the assembly sleeve 3 from being assembled too deeply. The moving unit is composed of at least two rows of moving bead rows, and each row of moving bead rows is composed of a plurality of balls 6. The right end faces of the assembly sleeve 3 and the main shaft are provided with semicircular grooves arranged along their length directions and for the installation of corresponding moving bead rows. The number of the semicircular grooves is the same as the number of moving bead rows, and the moving bead rows leave a spacing between the inner peripheral wall of the assembly sleeve 3 and the outer peripheral wall of the motor shaft 2.

[0014] To elaborate further, in order to improve the sealing performance, a convex ring portion 7 which protrudes radially outward and slides in contact with the motor shaft 2 is provided on the inner circumferential wall of the assembly sleeve 3 at the left end portion, so that the sealing performance at the gap is improved by the convex ring portion 7. A limiting ring 8 which is connected to the assembly sleeve 3 and is used to limit the position of the ball 6 is provided on the right end face of the assembly sleeve 3. The limiting ring 8 is also connected to the assembly sleeve 3 by a plurality of studs, and the inner circumferential wall of the limiting ring 8 slides in contact with the outer circumferential wall of the motor shaft 2.
