Problems solved by technology

The existing self-lubricating gear adopts the internal oil storage lubrication method of the gear, and the internal lubricating oil can gradually seep out from the tooth surface. The disadvantage is that the oil storage is small and the oil output is difficult to control. The method of lubricating material achieves the lubricating effect, and its disadvantages are that the self-lubricating material wears seriously, the lubricating material is easy to peel off, the strength of the gear is greatly reduced, the heat dissipation effect is poor, and the life of the self-lubricating gear is short

Embodiment Construction

[0021] see figure 1 and figure 2 , the gear tooth surface adopts the electrochemical method to process the honeycomb pattern, figure 1 figure 2 The black shaded part on the middle tooth surface is the metal-based self-lubricating material.

[0022] The metal-based self-lubricating material is clad in the strip groove 4 on the top of the tooth surface, the top strip chip removal groove 3 is spaced from the strip groove 4, and the wear debris generated during the gear meshing process can be Discharge from the top strip flute 3. On both sides of the self-lubricating material 1 of the driving gear, there is also the middle strip-shaped chip removal groove 5 spanning the entire tooth surface, and the grinding debris generated during the internal meshing process of the tooth surface is discharged in this way. The unprocessed area left on the tooth side is to ensure the strength of the gear and prevent fatigue fracture. The tooth root adopts a transitional design to effectivel...

Abstract

The invention relates to a honeycomb-shaped polygonal self-lubricating gear. Honeycomb-shaped grooves, strip-shaped grooves, middle strip-shaped chip grooves and top strip-shaped chip grooves are processed in a tooth surface of the honeycomb-shaped polygonal self-lubricating gear; the honeycomb-shaped grooves are positioned in the middle of the tooth surface, and are filled with self-lubricating materials; the strip-shaped grooves are positioned in the top of the tooth surface, and are filled with the self-lubricating materials; and the middle strip-shaped chip grooves and the top strip-shaped chip grooves separately penetrate through the whole tooth surface and are formed in the top of the tooth surface, are distributed in a spaced mode, and are beneficial for chip removal. The invention discloses the honeycomb-shaped polygonal self-lubricating gear which is inspired by a honeycomb shape based on the bionic idea; compared with an existing gear, the honeycomb-shaped polygonal self-lubricating gear has self-lubricating characteristics, does not need to additionally add media such as lubricating oil and lubricating grease, enriches a gear lubricating mode, and can meet normal operation when the gear is under extreme working conditions such as an oil-free working condition and an oil-lack working condition.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a honeycomb polygonal self-lubricating gear. Background technique [0002] Improving the lubrication characteristics of gears and simplifying gear lubrication equipment is an urgent problem to be solved in the entire gear design industry. The common gear lubrication methods mainly include churning lubrication, oil spray lubrication and oil drip lubrication, all of which require additional devices such as oil tanks and oil delivery pumps during design, which adds a lot of equipment and space, and increases the weight of the gearbox. In practical applications, such as rockets, aircraft, and submarines have limited space and have relatively strict requirements on their own weight. Lightweight, integrated, and convenient have become the key directions of research in various industries, and domestic and foreign countries are also actively exploring for this New way of lubricati...
