The power ends of these devices are usually coupled using keys, and before testing, a sleeve flange is mounted on the end of the drive shaft, which is then connected to a coupling. Generally, for the shaft sleeve which is axially installed, the shaft sleeve and the shaft end are required to be pre-installed and then can be tested on a bench. The test of each machine requires the shaft sleeve to be disassembled and assembled once. Tens of connecting bolts need to be removed during each disassembly, so that the preparation time of each test is prolonged, the test period is prolonged, and the working efficiency is reduced.

The technical scheme provided by the invention is that the quick mounting shaft sleeve flange comprises a shaft sleeve flange upper cover, a shaft sleeve flange lower cover, a pin shaft, a shaft nut, a fastening bolt and other parts. The shaft sleeve is characterized in that the upper flange cover and the lower flange cover of the shaft sleeve are connected through a pin shaft and can perform relative turning motion through the pin shaft. The upper cover is provided with a dynamic coupling key groove and a special-shaped hole for installing the upper cover and the lower cover, and the lower cover is provided with a round hole for the sliding of the shaft nut so that the shaft nut can slide in the hole of the lower cover.

The upper cover of the shaft sleeve flange is in interference fit with the pin shaft, and the pin shaft is prevented from sliding out in the movement process.

The lower cover of the shaft sleeve flange is in clearance fit with the pin shaft, and the lower flange rotates around the pin shaft.

The shaft nut is in clearance fit with a hole of the lower cover of the shaft sleeve flange, and certain roughness is guaranteed during processing, so that the shaft nut can slide in the hole.

The invention has the beneficial effects that: the invention has simple design structure and convenient processing; the ingenious structure can be applied to a test board for mass production of the movable equipment; when the tested device is replaced, the installation workload of shaft sleeve disassembly and assembly and dozens of bolts of a shaft sleeve flange is reduced, and the working efficiency is improved.

Detailed Description

As shown in fig. 1 to 6, the present invention discloses a shaft sleeve flange capable of being quickly disassembled and assembled, the quick-mounting shaft sleeve flange comprising: the flange comprises an upper flange cover 1, a lower flange cover 2, a pin shaft 3, a shaft nut 4, an inner hexagon bolt 5 and a spring gasket.

Firstly, an upper flange cover 1 and a lower flange cover 2 are connected together through a pin shaft 3 to form a hinge structure, wherein the pin shaft 3 and the upper flange cover 1 are in interference fit, the interference magnitude is controlled to be about 0.02mm for convenience of assembly, and the pin shaft 3 and the upper flange cover move together during rotation. Meanwhile, the pin shaft 3 is in clearance fit with the lower flange cover, so that the pin shaft 3 can freely rotate in a hinge hole of the lower flange cover.

The shaft nut 4 slides in the side hole of the flange lower cover 2 and can connect the flange upper cover and the flange lower cover together with the hexagon socket head cap screw and the spring gasket. The top of the flange upper cover is provided with a key groove for dynamic coupling with a key at the shaft end.

When the installation starts, the lower cover of the cover shaft sleeve flange is dragged into the transmission shaft, and the upper cover 1 of the flange is turned over and then is turned over with the lower cover 2. The inner hexagon bolt 5 and the shaft nut 4 slide into the special-shaped hole of the flange upper cover, and then the bolt is locked, so that the flange upper cover and the flange lower cover are tightly embraced on the shaft, and power transmission is performed.

After the assembly body parts are manufactured, the shaft sleeve flange is required to be integrally subjected to dynamic balance test so as to meet the dynamic balance requirements at different rotating speeds.

After the test is completed, the inner hexagon bolts can be loosened, the flange upper cover 1 is turned over, the test machine can be hoisted immediately, the whole driving shafting does not need to be disassembled, and the installation time is greatly shortened.

The invention discloses a shaft sleeve flange capable of being quickly disassembled and assembled, relates to the field of transmission and driving, and particularly relates to the field of frequent disassembling and assembling and replacing in power machinery test. Different from the traditional shaft sleeve flange which is axially disassembled and assembled, the flange is axially split and is radially folded for installation, so that the driving shaft system can be kept still during installation, and the power machine can be withdrawn only after the shaft sleeve is opened. The coupling is usually used in combination with universal joint couplings, bellows couplings and the like. Convenient and quick disassembly. The device is of a cover turning structure and consists of an upper flange cover and a lower flange cover, and the middle parts of the upper flange cover and the lower flange cover are connected through a rotating shaft. The bottom of the lower cover is provided with a special bolt hole, a sliding bolt shaft and other parts. The upper cover is provided with a key groove, and the key groove is mutually coupled with the protruding part of the shaft key to realize power transmission. The invention can be used in the field of testing of power machines in batch production, such as test tables of motors, compressors, pumps and the like, and can realize the quick installation of equipment driving sources.
