Problems solved by technology

[0004] 1. It is heated by oil cooking, resistance furnace, oven, etc. The heating equipment is simple, and it is heated and heated evenly. It is suitable for the assembly of bearings, but for the disassembly of bearings, due to the long heating time, the heat is transferred to the shaft, resulting in the bearing and shaft at the same time. Expansion, so it is usually supplemented by auxiliary tools such as presses, jacks, etc., resulting in serious damage to shafts and bearings
[0005] 2. The disassembly of bearings is achieved by direct heating with acetylene flames. This method not only pollutes the environment and wastes energy, but also causes deformation of the shaft and bearings due to uneven heating. The biggest disadvantage is that the heating temperature is not easy to control, and the bearing surface is e

Example Embodiment

[0034] In the present invention, the six radial magnetic conductors 8 and the six circumferential guide magnets 7 are arranged in sequence to form a magnetic conductor circle group. The six coils 9 are respectively sleeved on the six radial conductor magnets 8, and the two fixed rings 3 are respectively located on the conductor magnets. The upper and lower sides of the circumferential group; the front radial adjustment ring 2 and the back radial adjustment ring 5 are located on both sides of the two fixed rings 3, six fixing clips 1 and the front radial adjustment ring 2 and the back radial adjustment ring 5 The two handles 4 are threadedly connected to the circumferential guide magnet hole 13 on the circumferential guide magnet 7 and are symmetrically distributed about the center of the circle. The fixing rod 6 and the clamping rod 11 are respectively fixedly connected to the fixing clip In the two fixing clamp holes 24 on 1, the two ends of the two tie rods 10 are respectively...

Abstract

The invention discloses a variable-diameter bearing inner ring induction replacer, and belongs to the technical field of mechanical engineering and automation. In the induction replacer, radial magnetizers and circumferential magnetizers are arranged at intervals in turn; coils are sleeved on the radial magnetizers respectively; fixing rings are positioned on the upper side and the lower side of a magnetizer circumferential group; a front radial adjusting ring and a reverse radial adjusting ring are positioned on the two sides of each fixing ring respectively; a fixing clamp is fixedly connected with the front radial adjusting ring and the reverse radial adjusting ring; a handle is in threaded connection with circumferential magnetizer holes on the circumferential magnetizers; a fixing rod and a clamping rod are fixedly connected in two fixing clamp holes on the fixing clamp; the two ends of two pull rods are connected to the fixing rod and the clamping rod through bolts; guide pillar bearings which are arranged at the two ends of a guide pillar are in clearance fit with a front radial adjusting ring spiral groove and a reverse radial adjusting ring spiral groove respectively; and a rolling ball retaining frame in a rolling body is fixedly connected with the fixing rings 3. Through the induction replacer, bearing inner rings of different external diameter sizes can be quickly and nondestructively disassembled and assembled, and the surface temperatures of the bearing inner rings are easy to control; and the induction replacer can also be used for an interference assembly line of a bearing and has the advantages of low cost, low energy consumption and no pollution.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering and automation. Background technique [0002] In the process of equipment assembly, maintenance or prototype debugging, it is often necessary to disassemble and install bearings. For example, for rail vehicles, on the one hand, the bearings of the vehicle are subject to alternating stress for a long time and are easily damaged and need to be replaced; for disassembly. However, often the inner ring of the bearing is fitted onto the shaft with interference, which makes it difficult to disassemble the inner ring of the bearing. [0003] At present, there are mainly the following methods for traditional bearing interference assembly and disassembly at home and abroad: [0004] 1. It is heated by oil cooking, resistance furnace, oven, etc. The heating equipment is simple, and it is heated and heated evenly. It is suitable for the assembly of bearings, but for the disassembly of bearin...
