Description
Technical Field
The utility model belongs to the technical field of the press, especially, relate to a press clutch bearing installation protection architecture.
Background
The cylindrical ball bearing of the flywheel is a part between the flywheel and a high-speed shaft of the press, and at present, the press often has the damage fault of the ball bearing of the cylindrical ball bearing of the flywheel, so that serious economic loss is caused for our company, and the product quality image is seriously influenced.
Through research and analysis, the reason for causing the damage of the cylindrical ball bearing is found out as follows: in the process of installing the flywheel, the bearing inner ring and the inner spacer sleeve are thermally installed on the high-speed shaft, the bearing outer ring, the ball sleeve and the outer spacer sleeve are installed in an inner hole of the flywheel, and then the flywheel assembly is integrally hoisted and assembled on the high-speed shaft. As the flywheel weighs about 10 tons, the cylindrical ball of the bearing is easy to collide with the inner ring of the bearing under a large stress in the assembling process to damage the inner ring of the bearing, and when the flywheel works, the damaged parts of the inner ring of the bearing are rapidly expanded under periodic load to form serious defects, and finally the bearing is damaged.
SUMMERY OF THE UTILITY MODEL
Problem to prior art existence, the utility model provides a press clutch bearing installation protection architecture of the problem of solving the easy damage of flywheel bearing.
The utility model discloses a realize like this, a press clutch bearing installation protection architecture, its characterized in that: the flywheel brake device comprises a high-speed shaft, wherein an inner spacer sleeve is fixedly sleeved on the high-speed shaft, a bearing inner ring is fixedly sleeved on the inner spacer sleeve, a guide sleeve is sleeved in a gap of the bearing inner ring, a ball sleeve is sleeved in a gap of the guide sleeve, a bearing outer ring is sleeved on the outer side of the ball sleeve, an outer spacer sleeve is fixedly sleeved on the outer side of the bearing outer ring, and a flywheel is fixedly sleeved on the outer spacer sleeve; the guide sleeve is provided with a circumferential sleeve arranged between the bearing inner ring and the ball sleeve, a supporting ring sleeve is arranged at the end part of the circumferential sleeve, and the supporting ring sleeve is sleeved on the high-speed shaft in a movable mode along the axial direction of the high-speed shaft.
The clearance value of the cylindrical ball of the bearing and the bearing inner ring is about 0.20mm-0.30mm, and a circumferential sleeve is additionally arranged between the cylindrical ball sleeve of the bearing and the bearing inner ring of the bearing mounting structure. The circumferential sleeve is a light protection structure with small thickness and qualitative rigidity, and can collide with the bearing inner ring in the sleeving process, but the bearing inner ring cannot be damaged due to extremely small self mass. After the circumferential sleeve is assembled on the inner ring of the bearing, the inner ring of the bearing can be protected, the inner ring of the bearing is prevented from being collided and damaged in the installation process of the flywheel assembly with large mass, and after the installation of the flywheel assembly is completed, the inner ring of the bearing can be pulled out of the circumferential sleeve. Above-mentioned installation protection architecture can effectively avoid the bearing inner ring impaired in the assembly process to effectively sing the life of part.
In the above technical solution, preferably, the circumferential sleeve and the support ring sleeve are welded to form an integral structure.
Threaded holes are uniformly distributed on the circumference of the end face of the supporting ring sleeve.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
For solving the problem that flywheel bearing harmd easily, the utility model particularly provides a press clutch bearing installation protection architecture, this mounting structure can effectively prolong flywheel bearing's life, avoids the trouble to produce. For further explanation of the structure of the present invention, the following detailed description is made with reference to the accompanying drawings:
referring to fig. 1, a press separator bearing installation protection structure includes a high-speed shaft 1, an inner spacer 2 fixedly sleeved on the high-speed shaft 1, and an inner bearing ring 3 fixedly sleeved on the inner spacer 2. Specifically, the bearing inner ring 3 and the inner spacer 2 are thermally mounted on the high-speed shaft 1.
The bearing inner ring 3 is sleeved with the guide sleeve 4 in a clearance mode, the guide sleeve 4 is sleeved with the ball sleeve 5 in a clearance mode, the bearing outer ring 6 is sleeved on the outer side of the ball sleeve 5 in a clearance mode, the outer spacer 7 is fixedly sleeved on the outer side of the bearing outer ring in a sleeving mode, and the flywheel 8 is fixedly sleeved on the outer spacer 7 in a sleeving mode. Specifically, the guide sleeve 4 is sleeved outside the bearing inner ring 3, the ball sleeve 5, the bearing outer ring 6 and the outer spacer 7 are sleeved in an inner hole of the flywheel 8 to form a flywheel assembly and are hoisted, and the sleeved structure of the ball sleeve 5, the bearing outer ring 6, the outer spacer 7 and the flywheel 8 is a known conventional technology.
