The actual machining effect of the key components of the shaft through the curved road structure. The processing technology of the key components of the shaft through the curved road structure has been verified by the production for a long time, which effectively ensures the reliability of the motor operation and the requirements of the explosion-proof performance. The guarantee for the processing accuracy of the terminal sleeve for the junction box. The structural characteristics of the terminal sleeve, YB132～315 terminal sleeve is made by 4220 amino-pressure plastic and processed into a threaded copper sleeve. The key to processing is to ensure the accuracy of the inner hole after hot pressing. The terminal sleeve hot press forming process analysis The flameproof motor terminal sleeve is pressed and formed by 4220 pressure plastic, and the dIIB inner hole size accuracy is within the range, and the current process is sufficient to ensure.
The dIIC explosion-proof motor is manufactured. The accuracy of the inner hole cannot be guaranteed according to the current process. The main reasons are as follows: (a) The material shrinkage rate varies widely, and the difference between the inner holes and the same material is the same. ~0.15. (b) Different cooling rates, the range of shrinkage varies widely, and room temperature has a great influence on the shrinkage rate of the material. (c) Process parameters such as heating temperature, unit pressure, and curing time also have a large effect on the accuracy of the inner hole.
Process assurance of terminal sleeve machining accuracy. In order to ensure that the processing precision of the terminal sleeve meets the technical requirements, the key process guarantee measures adopted are as follows: 1 The compression molding die adopts a molding method of 4 pieces, and the mandrel of the compression molding mandrel is 0.02 size. 2 Limiting the amount of shrinkage of the inner hole A mandrel of a previously machined size is inserted into the inner hole of the workpiece after the workpiece is demolded to limit the amount of shrinkage.
End cap processing accuracy guarantee. Difficulties in the processing accuracy of the end cap, the difficulty in ensuring the accuracy of the end cap processing, in addition to reducing the deformation caused by the machining process, the key difficulty is caused by the deformation after the hydrostatic test. The main reason for the deformation of the end cap hydraulic pressure test is that the workpiece pressing position is at the outer end surface of the bearing, and the workpiece is deformed by the bending force.
Fc 207 Bearing description
Fc 207 Bearing,the most commonly used type of mounted units, are designed to provide shaft support where the mounting surface is parallel to the shaft axis. The bolt holes are usually slotted for adjustment during mounting. Pillow blocks are supplied in a variety of configurations. Pressed steel pillow block bearings are also available for light-duty applications.
