Gear with dust storage function

Abstract

The invention relates to a gear with a dust storage function. The gear comprises a gear body, key slots and a center hole, wherein the center hole is formed in the middle of the gear body; the key slots are formed in the inner wall of the center hole; the gear body comprises wheel teeth and tooth slots; each tooth slot is formed by two adjacent wheel teeth; an inclined strip-type slot A is formed in the radius direction of the gear body along the lower surface of each tooth slot and is communicated with a strip-type slot B, and the inner wall of each strip-type slot A is connected with a baffle. Due to the arrangement of the strip-type slots A and the strip-type slots B and the arrangement of the baffles on the inner walls of the strip-type slots A, dust produced in a meshing process of the gear can slide into the strip-type slots B through the strip-type slots A; in the rotating process of the gear, due to the arrangement of the inclined baffles, the dust can be prevented from sliding out of the strip-type slots B; the influence caused by the dust on gear transmission can be prevented by storing and regularly cleaning the dust.

Description

Technical field [0001] The invention relates to a gear, in particular to a gear with a chip storage function. Background technique [0002] Gears are toothed mechanical parts that can mesh with each other. They are widely used in mechanical transmission and the entire mechanical field. Modern gear technology has reached: gear modulus 0.004 to 100 mm; gear diameter from 1 mm to 150 meters; transmission power can reach 100,000 kilowatts; rotation speed can reach hundreds of thousands of revolutions per minute; the highest peripheral speed can reach 300 meters / second. [0003] According to the Chinese Patent Authorization Announcement No. CN 202883947 U, a gear has changed from one slot in the original technology to two slots, and they are symmetrically distributed on both sides of the gear, which can prevent gear deviation to a certain extent. However, on high-speed rotating gears, this approach still cannot reduce the wear of the slot. At the same time, because the speed is too h...

Problems solved by technology

[0003] According to a gear published by the Chinese patent authorization announcement number CN 202883947 U, one slot in the prior art is changed into two slots, which are symmetrically distributed on both sides of the gear, so that to a certain extent, the gear can be prevented from being skewed. However, on high-speed rotating gears, this method still cannot reduce the wear of the card slot. At the same time, due to the high speed, it is necessary to add lubricating oil to the connection between the gear and the shaft in time to improve its use effect.

The disadvantage of this structure of gears is that during the meshing process of the gears, friction occurs between the teeth of one gear and the tooth grooves of the other gear, and this friction will generate wear debris. If the wear debris is not cleaned for a long time , will affect the gear transmission, and even cause the gear transmission to fail
