The invention discloses a novel rust-proof gear shaft. The novel rust-proof gear shaft comprises a shaft body and a first step surface, wherein the first step surface is arranged on one side of the shaft body, a plurality of oil holes are formed in each connecting point of the shaft body and are formed in the inner connecting points of the shaft body, a second step surface is arranged on the other side of the shaft body, a third step surface is arranged on the outer side of the first step surface, a key is formed in the longitudinal surface of the shaft body, the key is communicated with the second step surface, a tightening head is arranged at the outer end of the third step surface, and a tightening notch is formed in the tightening head. Different models and varieties of gears can be mounted through the novel rust-proof gear shaft. When a corresponding gear mounting cap is damaged, only a new gear mounting cap needs to be changed. An intermediate gear shaft main body does not need to be changed. The gear shaft can be conveniently tightened and fixed in mounting and maintaining processes through the tightening notch. A rust-proof effect is realized under damp conditions, and the service life is prolonged.
Description
technical field [0001] The invention relates to the technical field of gears, in particular to a novel anti-rust gear shaft. Background technique [0002] Gear is a kind of widely used mechanical parts. Its basic structure is that two gears with different sizes are fixed on one shaft. The size requirements of the bridge are very strict, and correspondingly, the diameter requirements of the bridge gear shaft are also very strict. The bridge gear shafts of the same type can only be gears with the same type of assembly, which is prone to rust for a long time, increases the manufacturing cost of the machine, and cannot adapt to wider market demand. Contents of the invention [0003] The object of the present invention is to provide a new type of anti-rust gear shaft that can be installed with different types of gears in view of the defects and deficiencies of the prior art. [0004] A novel anti-rust gear shaft according to the present invention comprises a shaft body and a ...
