Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bearing lubrication, in particular to a grinding bearing auxiliary lubrication component. BACKGROUND

[0002] The press (including punch, hydraulic press) is a kind of general-purpose press with exquisite structure. It has the characteristics of wide application and high production efficiency. The press can be widely used in cutting, punching, blanking, bending, riveting and forming processes. The press is driven by the motor through the transmission mechanism to drive the working mechanism to apply process force to the workpiece. The transmission mechanism is a speed reduction mechanism of belt transmission and gear transmission. The working mechanism is divided into screw mechanism, crank connecting rod mechanism and hydraulic cylinder. The metal blank is subjected to a large pressure to make the metal deform plastically and break to process into parts.

[0003] The traditional lubrication of the main shaft of the press is generally divided into two kinds: one is lubricating oil, and the oil pipe is arranged at the bearing seat to drip lubricating oil for lubrication; the other is lubricating grease, which is extruded and applied to the side surface of the bearing.

[0004] However, if the lubrication is not replenished in time or the lubrication system fails, and the routine inspection is not noticed, the rotating part does not get the lubrication effect, and wear occurs during operation, which causes the equipment to stop production or damage, resulting in huge losses.

[0005] Therefore, the present application provides a grinding bearing auxiliary lubrication component, so that the bearing still has good lubrication effect in a short period after the lubrication system fails. CONTENT OF THE UTILITY MODEL

[0024] The technical solutions in the embodiments of the application will be described below with reference to the accompanying drawings. Figures 1-5 It is obvious that the embodiments described are only a part of the embodiments of the application, rather than all the embodiments of the application.

[0025] In order to solve the problems in the prior art, the embodiment provides a grinding bearing auxiliary lubricating member, which comprises a ring-shaped holder 2 arranged on a main shaft 1, and an embedding groove 10 for embedding a bearing is arranged on the upper end of the holder 2.

[0026] The principle details of the embodiment are as follows:

[0027] The grinding bearing auxiliary lubricating member comprises a ring-shaped holder 2, the holder 2 is sleeved on the main shaft 1, and the inner ring 3 of the holder 2 is in interference fit with the sleeving part on the main shaft 1, so that the holder 2 is fastened on the main shaft 1. The upper end of the holder 2 is provided with the embedding groove 10 for embedding the bearing.

[0028] In the embodiment, the type of the bearing is a tapered roller bearing, the inner ring 3 of the bearing is embedded in the embedding groove 10, and the outer ring 4 of the bearing is embedded in the externally arranged bearing seat.

[0029] In use, when the lubricating system is normally operated or the lubricating oil is sufficient, the lubricating oil is accumulated in the embedding groove 10, so that the bearing is always immersed in the lubricating liquid. When the lubricating system fails, the lubricating liquid remaining in the embedding groove 10 can continue to play a lubricating effect, and in a short time, the rotating part will not be seriously worn, and the lubricating protection effect can be achieved in a short time.

[0030] In a further embodiment of the scheme, the height of the embedding groove 10 is not less than 2 / 3 of the outer leakage size of the side of the inner ring 3 of the tapered roller bearing, and does not enter the height range of the outer ring 4. A certain amount of lubricating liquid storage can be left to ensure that the inner ring 3 and the outer ring 4 of the bearing are always immersed in the lubricating liquid.

[0031] In a further embodiment of the scheme, the bottom wall of the embedding groove 10 is provided with an oil storage groove 5, and the side wall of the embedding groove 10 is provided with an oil permeation hole 6 penetrating the oil storage groove 5. The oil storage groove 5 is arranged to increase the storage amount of the lubricating liquid. The oil permeation hole 6 is arranged to facilitate the penetration of the lubricating liquid after assembly is completed.

[0032] In a further embodiment of the scheme, the oil permeation hole 6 is provided with a plurality of oil permeation holes. The lubricating liquid can be easily penetrated, and even if one oil permeation hole 6 is blocked, the penetration of the lubricating liquid will not be affected.

[0033] In a further embodiment of the scheme, the oil permeation hole 6 is arranged to be inclined. The inclination direction is matched with the rotation direction of the main shaft 1, so as to prevent the lubricating liquid from being thrown out during rotation.

[0034] In a further embodiment of the scheme, the inner ring 3 of the holder 2 is provided with a stepped groove 7 below the embedding groove 10, the main shaft 1 is provided with a stepped part 8 matched with the stepped groove 7, and the stepped part 8 is in transition fit with the stepped groove 7.

[0035] The principle of the embodiment is as follows:

[0036] The main shaft 1 is provided with a boss to form a step 8, and the step 8 provides a mounting and positioning base for the bearing inner ring 3. The diameter of the large end face of the step 8 is smaller than the outer diameter of the bearing inner ring 3, avoiding rotation interference. The bearing inner ring 3 of the holder 2 is provided with a step groove 7 below the embedding groove 10, and the step groove 7 is the same shape as the step 8, and the size is a transition fit, and the interference amount is not more than 3 silk. The transition fit makes the holder 2 not easy to fall off after being embedded in the step 8 through the step groove 7. The presence of the step 8 also adapts to change the minimum diameter of the bearing inner ring 3 of the holder 2, so that the gap between the bearing inner ring 3 of the holder 2 and the main shaft 1 becomes larger. When dismounting the holder 2, knock the end of the holder 2, so that the step groove 7 and the step 8 are separated, and then it can be directly taken down, and the dismounting is more convenient.

[0037] In a further embodiment of the present application, the horizontal contact surface of the step groove 7 and the step 8 is provided with a clamping groove, and a sealing ring 9 is clamped in the clamping groove. Form a seal to prevent lubricating liquid from seeping from the contact surface between the step groove 7 and the step 8.
