Description
Technical field
The utility model relates to retarder, is specifically related to the worm type of reduction gearing that a kind of input shaft end plates antirust chromium.
Background technique
Worm type of reduction gearing is a kind of power-transmitting unit, and it can realize exporting and the transmission of input Vertical direction.Velocity ratio is large, and mechanism is compact, and two-wheeled engagement is cambered surface contact, and bearing capacity is large.Stable drive, noise are little.Mechanism has self-locking performance, can play safety protection effect.Therefore, worm type of reduction gearing is widely used in machinery industry.
Chromium is a kind of alloying element, and hardness is large, at air (or water) even in red-hot not oxidizable yet, there is very high corrosion resistance, be plated on metal and there is protective action.Tradition worm type of reduction gearing, when using process touches mordant liquid or gas, easily causes reducer input shaft to get rusty, causes corrosion and damage, thus damage Sealing causes leakage of oil, shortens the working life of retarder.Therefore, be plated on the input end of retarder by corrosion resistant chromium, avoid the corrosion of reducer input shaft, protection Sealing, reduces lubricant oil leakage of oil possibility in reducer shell greatly, improves the working life of retarder.
Model utility content
The worm type of reduction gearing that the technical problems to be solved in the utility model is to provide a kind of compact structure, operates steadily, safe and reliable, input shaft end that is long service life plates antirust chromium.
The technological scheme that the utility model solves the problems of the technologies described above is: provide a kind of input shaft end with following structure to plate the worm type of reduction gearing of antirust chromium, comprise casing 1, worm screw 2 is installed in casing 1, worm screw 2 two ends are respectively connected with a worm bearing, described worm screw 2 two ends are crossed casing 1 and are stretched out casing 1 and form the input shaft 3 be connected with motor output end outward, the two ends input shaft 3 stretched out outside casing is all coated with antirust layers of chrome, the worm gear 4 of the transmission that to be meshed with worm screw 2 is provided with below worm screw 2, the two ends of worm gear 4 are respectively arranged with a Worm Bearing 5, Worm Bearing lid 6 is provided with between Worm Bearing 5 at one end and casing 1.
Preferably, described Worm Bearing 5 is angular contact bearing, can improve and export bearing capacity and rigidity.
Preferably, described Worm Bearing lid 6 is provided with the retaining thread hole 7 with other equipment connections, in described retaining thread hole 7, studs with Stainless Steel Wire swivel nut, strengthen worm tooth intensity.
