Bushing applications
PubTime:2018-01-22 Socure:www.brassbush.com Author:
Bushing is used for mechanical parts, in order to achieve sealing, wear protection and other supporting parts, is the role of liner from the ring. In the field of valve applications, bushings within the bonnet, the general use of PTFE or graphite and other anti-corrosion materials, used for sealing.
Used in: packaging machinery, textile machinery, mining machinery, metallurgical machinery, printing machinery, tobacco machinery, forging machinery, various types of machine tools and interchangeable mechanical transmission links. For example: Pulley, sprocket, gear, propeller, large fan and other connections; Features: Torque, high precision, convenient assembly and disassembly, simple operation, good positioning, reduce the rejection rate with the shaft and hub, Reusable, without damage to the mating surface, is the most ideal and most economical choice.
1, Installation: Expansion sets in the factory has been coated with lubricating oil, can be installed directly. First of all, install the screw in the other part of the screw into the three bolts evenly distributed along the circumference, the inner sleeve, coat the top open. Then put the expansion sleeve into the hub hole of the designed position, tighten the bolt by using the force measuring board, and tighten the method only by screwing each bolt to 1/4 of the rated torque at a time. The order of tightening is at the slit, Left and right cross-tightening followed by tightening to ensure that the rated torque value.
2, disassembly: first remove all bolts to loosen a few laps. Then tighten the bolt-on expander sleeve cross-wise inside the removed screw hole.
3, protection: installation to prevent the expansion of pollution. In open-air work or poor working environment on the machine, should be regularly exposed on the expansion of the end face and bolts coated with anti-rust grease, anti-rust should be used better expansion type. Expansion tight coupling sleeve is a modern new advanced mechanical foundation. Is a new type of keyless coupling device widely used in today's world to realize the transmission of load through the pressure and friction generated between the containing surfaces by widely tightening the 12.9 high-strength screws
