Description

Technical Field

[0001] This utility model relates to the field of mechanical connection accessories technology, specifically to an elbow plate pad for wear prevention and oil injection. Background Technology

[0002] A crusher, also known as a stone crusher, is a machine used in the processing of metal and non-metal minerals to crush mined raw ore into small particles through compression and bending. The toggle plate is a safety part of the crusher. When uncrushable material falls into the crusher and causes the machine to exceed its normal load, the toggle plate will break immediately, and the crusher will stop working to prevent damage to the entire machine.

[0003] Existing elbow plate gaskets are mostly made of ordinary steel with no special wear-resistant treatment on the surface. They are prone to wear and deformation after long-term friction, resulting in increased connection gaps. Furthermore, the contact surface can only be lubricated after disassembling the equipment, which is cumbersome. The surface is smooth and lacks an oil storage structure, resulting in poor lubrication retention and easy loss of lubricating oil, making it impossible to form continuous lubrication. In order to solve the above problems, an elbow plate gasket for wear prevention and lubrication is proposed. Utility Model Content

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] The integrated oil injection channel and oil storage structure enable oil injection without disassembling the equipment. It also has strong lubricant retention capacity and significantly extends the lubrication cycle. The groove and oil outlet design ensure that the lubricant evenly covers the friction surface, avoiding abnormal wear caused by local dry friction.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figures 1-4As shown, this utility model provides an elbow plate anti-wear lubrication pad, including a pad 1. The two opposite sides of the pad 1 are arc-shaped surfaces 10 adapted to the contact surface of the elbow plate. The two sides of the pad 1 are in close contact with the surface of the elbow plate. The inner ring surface of the arc-shaped surface 10 has several grooves 7, and the inside of each groove 7 has several oil outlet holes 8. The lubricating oil flowing out of the oil outlet holes 8 flows into the interface between the pad 1 and the elbow plate surface, preventing damage to the elbow plate due to prolonged friction. The cross-section of the grooves 7 is semi-circular, and the diameter of the oil outlet holes 8 is 2-4 mm. mm, and the oil outlet holes 8 in each groove 7 are evenly distributed. The center of the top of the pad 1 is provided with a mounting hole 2. The pad 1 can be installed on the concentric shaft surface of the elbow plate through the mounting hole 2 and move synchronously with the elbow plate. An oil storage ring 3 is fixedly installed on the inner ring surface of the mounting hole 2. The lubricating oil inside the oil storage ring 3 is transmitted to the inside of each oil outlet hole 8 through the oil supply pipe 9. Several oil supply pipes 9 are fixedly installed on the inner wall of the pad 1. One end of the oil supply pipe 9 is connected to the oil storage ring 3, and the other side of the oil supply pipe 9 is connected to the oil outlet hole 8.

[0019] A pre-embedded groove is provided at the center of one side of the pad 1, and an oil filling pipe 6 is fixedly installed inside the pre-embedded groove. One side of the oil filling pipe 6 extends into the inside of the oil storage ring 3.

[0020] By adopting the above technical solution, when the amount of lubricating oil inside the oil storage ring 3 is small, the external oil pipe can be connected to one side of the filling pipe 6, and the external lubricating oil can be transferred to the inside of the oil storage ring 3 through the filling pipe 6, thereby achieving the effect of oil storage and providing long-term oil lubrication at the junction of the elbow plate and the pad plate 1.

[0021] A threaded cap 4 is threadedly connected to the other side of the inner cavity of the refueling pipe 6, and a sealing gasket 5 is fixedly installed on the surface of the threaded cap 4.

[0022] By adopting the above technical solution, when it is necessary to add lubricating oil to the inside of the oil reservoir ring 3, the threaded cap 4 can be rotated to remove it from one side of the inner cavity of the oil filling pipe 6, and the oil reservoir ring 3 can be lubricated through the oil filling pipe 6. After the oil reservoir ring 3 is lubricated, the threaded cap 4 is screwed back into one side of the inner cavity of the oil filling pipe 6. The sealing gasket 5 set on the surface of the threaded cap 4 effectively prevents lubricating oil from seeping out from the gap between the threaded cap 4 and the oil filling pipe 6.

[0023] The inner wall of the mounting hole 2 is provided with a wear-resistant sleeve made of bronze. The pad 1 is made of high-chromium cast iron or high-manganese steel. The wear-resistant sleeve effectively prevents the mounting hole 2 from being subjected to excessive friction, which would cause the pad 1 to shake.

[0024] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
