Problems solved by technology

[0002] Due to the large output torque of the motor, the punching plate and the shaft are designed to be an interference fit. In the past, the company’s 2- and 4-pole motor copper bar without tie-rod rotor core laminations used to directly heat the rotor punching plate, and then put multiple pieces into it. This process is difficult to operate and cannot control the pressure between the sheets, which will easily cause deformation of the air passage, affect the heat dissipation of the motor coil and the alignment of the magnetic center

Embodiment Construction

[0005] Laminate the laminations on the lamination tire first, press the outside of the iron core through the pressure tire, and after the lamination tire is withdrawn, heat the iron core and thermally install it with the rotating shaft.

[0006] The design concept is based on the direction of operation safety and energy saving. It adopts low-cost and commonly used Q235B steel plate material. It uses equipment for blanking and welding, and then rough and finish machining on a lathe. It has a simple structure and strong versatility. Safe operation and reliable quality.

[0007] After a large number of motor 2 and 4 pole copper row rotors, the design is based on the size statistics of the non-tie rod iron core. It is suitable for the structure of the motor product, has good versatility and can meet the requirements of the inter-chip pressure. While ensuring product quality, it eliminates potential safety hazards, saves energy, and reduces production costs.

Abstract

The invention discloses a process of a novel 2 to 4-electrode copper bar motor lamination press mounting tire which is simple in structure, high in universality, low in manufacturing cost and high in operation security. The product quality is ensured, and meanwhile potential safety hazard is eliminated for companies, the energy is saved, and the production cost is lowered.

Description

technical field [0001] The laminated press-fitted tire of the present invention is mainly used in the manufacture of 2- and 4-pole motor rotors with high-torque iron cores without tie rods. Background technique [0002] Due to the large output torque of the motor, the punching plate and the shaft are designed to be an interference fit. In the past, the company’s 2- and 4-pole motor copper bar without tie-rod rotor core laminations used to directly heat the rotor punching plate, and then put multiple pieces into it. This process is difficult to operate and cannot control the pressure between the sheets, which will easily cause deformation of the air passage, affect the heat dissipation of the motor coil and the alignment of the magnetic center. Contents of the invention [0003] In order to solve the above problems, a new type of lamination press tire with good operation safety, guaranteed groove bottom uniformity and lamination coefficient is designed. After the press-fit...
