Detailed Description
The technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments, and all other embodiments obtained by those skilled in the art without making creative efforts based on the embodiments of the present utility model are included in the protection scope of the present utility model.
Examples: please refer to a connection structure between bucket wheel axle and bucket wheel seat shown in fig. 1-4, including bush 1, offer spacing protruding 2 on the outer wall of bush 1, offered oil groove 3 on the inner wall of bush 1, offered thread groove 4 on the lateral wall of bush 1, threaded connection has installation base 5 on the inner wall of thread groove 4, threaded connection has fixed section of thick bamboo 6 on the outer wall of installation base 5, installs flexible fender 7 on the inner wall of fixed section of thick bamboo 6, installs elasticity on the inner wall of flexible fender 7 and separates and keep off 8, and elasticity is kept off one side of 8 and is located the one end that the flexible fender 7 was enclosed and install elasticity casing 9.
In this embodiment, referring specifically to fig. 1, fig. 2, fig. 3 and fig. 4, the lining 1 is made of CuSn8P copper alloy material, the limiting protrusion 2 is in an annular structure, the oil groove 3 is in an annular structure, the inner cavity of the oil groove 3 is provided with lubricating oil material, the thread groove 4 is located on two sets of opposite side walls of the lining 1, the mounting base 5 is provided with two sets of threads and is located on the inner walls of the thread groove 4, the fixing barrel 6 is provided with two sets of threads and is located on the inner walls of the mounting base 5, the flexible enclosure 7 and the elastic barrier 8 are made of wear-resistant rubber material, the elastic barrier 8 is in an annular structure, the cross section of the elastic shell 9 is in a concave structure, the inner wall of the elastic shell 9 is provided with lubricating oil material, and the flexible enclosure 7 is provided with two sets of threads and is located on the inner wall of the fixing barrel 6.
Wherein, the flexible material that encloses fender 7 and elasticity and keep off 8 is wear-resisting rubber materials, and elasticity keeps off 8 and is annular structure, and elasticity keeps off 8 better laminating on the outer wall of axis of rotation for the greasy dirt of adhesion on the axis of rotation outer wall receives elasticity and keeps off 8 and stop.
The bearing structure of this scheme convenience dismouting is at the during operation, through substituting holder, rolling element and bearing with bush 1, make connect through bush 1 between bearing box and the bucket wheel axle, because bush 1 and bucket wheel axle direct contact and there is relative motion, both can have wearing and tearing, for the protection bucket wheel axle, consequently, adopt the wearability far less than bucket wheel axle and the cheaper material of price, select CuSn8P as the material of bush 1 promptly, wearing and tearing mainly take place on the copper sheathing during operation, short-term influence is less to bucket wheel axle, and the copper sheathing design accords with former bearing radial dead load, axial dead load, the design requirement of axial dynamic load, the problem that leads to bearing lubrication failure after the dust gets into inside has been solved, also solved because the inside of the bearing has dust granule friction for a long time, lead to the holder of bearing inner wall, rolling element and raceway etc. can appear wearing and tearing problem.
The installation base 5 is connected to the inner wall of the thread groove 4 in a threaded manner, the fixing barrel 6 is connected to the outer wall of the installation base 5 in a threaded manner, the flexible enclosing baffle 7 is arranged on the inner wall of the fixing barrel 6, the elastic baffle 8 is arranged on the inner wall of the flexible enclosing baffle 7, the elastic shell 9 is arranged on the inner wall of the elastic shell 9 under the action of lubricating oil materials, the elastic shell 9 is sleeved on the outer wall of the rotating shaft, the elastic shell 9 is provided with certain elasticity, the elastic shell 9 is well attached to the outer wall of the rotating shaft, lubricating oil in the inner cavity of the elastic shell 9 plays a role in primary sealing, dust and lubricating oil around the rotating shaft are fused into solid greasy dirt, the elastic baffle 8 is sleeved on the outer wall of the rotating shaft and fixed at one end of the flexible enclosing baffle 7, the elastic baffle 8 blocks greasy dirt on the outer wall of the rotating shaft, and is prevented from entering the bearing through multiple blocking, so that the outside dust is not easy to enter the inside the bearing, and the service life of the device is prolonged. By means of the design, the problems that although the split bearing is provided with the sealing dustproof structure, the device runs in a dust environment for a long time, the protection effect of a single sealing structure on dust infiltration is not very good, and dust can infiltrate into the split bearing after long-time use are solved.
