The model utility content
The purpose of the utility model is;, internal spline excessive to the ubiquitous casing volume of traditional crimping machine main transmission gearbox and external splines mesh tooth face are easy to wearing and tearing; And a series of problems such as operational noise is bigger, a kind of main transmission gearbox of new driving cold rolling crimper is provided.
The purpose of the utility model is achieved in that a kind of main transmission gearbox that drives cold rolling crimper; Comprise casing, be provided with the identical independent transmission system of two-way speed ratio in the casing, the output gear shaft center hole of two-way independent transmission system is equipped with internal spline; Two output gear shaft homonymy outputs; It is characterized in that: independent transmission system comprises input gear shaft, reduction gear axle and output gear shaft, and they are supported on the casing through bearing is parallel, are installed with the deceleration gearwheel through key on the reduction gear axle; Deceleration gearwheel engagement on input gear shaft and the reduction gear axle, the reduction gear axle with mesh with output gear shaft; The center hole hole of road output gear shaft of closing on outlet side is at least than the big 35mm in center hole aperture of another road output gear shaft; Be equipped with the oil baffle of a concentric in each output gear shaft away from the center hole end of output terminal one side, the endoporus aperture of oil baffle is than the little 20 ~ 30mm in this output gear shaft center hole aperture.
In the utility model: said two-way independent transmission system is symmetricly set on the both sides, output medial axis of gear-box.
In the utility model: two output gear shafts are equipped with independently lubricant oil injection pipe, and the jet of lubricant oil injection pipe is positioned at output gear shaft away from outlet side and point to center hole.
In the utility model: described internal spline is to be extended internally by the center hole end that output gear shaft closes on outlet side, and the physical length of internal spline section is at least 1/3rd of output gear shaft length.
In the utility model: on the output medial axis of casing output terminal, be provided with the unsteady spring bearing of male splined shaft; After two radicles are the inside and outside suit with one heart of the splined shaft of external splines; The external splines of their ends passes the male splined shaft spring bearing that floats and gets into casing, respectively with the output gear shaft center hole of two-way independent transmission system in the engagement of internal spline coupling.
The purpose of the utility model is: owing to change traditional intermediate gear shaft into the reduction gear axle, under the prerequisite that does not influence the input/output terminal speed ratio, can reduce the gear diameter of output gear shaft greatly, make the overall structure of gear-box compact more; Owing to directly lubricant oil is introduced center hole through the lubricant oil injection pipe; Be equipped with simultaneously the oil baffle of a concentric in each output gear shaft away from the center hole end of output terminal one side; The liquid level that can promote the lubricant oil in the center hole reaches; The lubricant oil that gets into center hole can only be flowed out by the center hole end of closing on output terminal one side along internal spline and external splines mesh tooth face, when guaranteeing that internal spline and external splines mesh tooth face are lubricated, has reduced the operational noise of gear-box.
