Abstract
The utility model discloses an easy just valve drive mechanism of abrasionproof that changes, including base, transmission nut, retaining ring, lead screw, handle, lock nut, set screw, bearing, transmission nut installs in the base, the lead screw is installed in transmission nut, the retaining ring is installed in the base upper end, the handle is installed on transmission nut but fixedly by lock nut, the last bearing of still installing of transmission nut is but fixed on the base by the retaining ring. Through drive a recess installation bearing on the valve base to it slides from top to bottom to add the fixed transmission nut of a retaining ring on the recess. Not only make valve be liable to change when transmission nut damages, also make transmission nut's friction rotate the ball roll that becomes the bearing, not only increased transmission nut's life, reduced transmission nut's damage frequency, make production go on smoothly. Also make the valve can not influence production when changing transmission nut.
Description
Technical field
The utility model relates to valve rotating mechanism, particularly relates to a kind of easy replacing and the tappet gear of abrasionproof.
Background technique
Power station mainly provides power source medium for company's main body factories and miness, send steel-making pneumatics air valve to bear and send whole steel to prick the effect of safe, the steady foot supply of section pneumatics wind.In this valve process of operation, Stem Mut will affect the operation of valve after damage, and Stem Mut is foundry goods cannot repair.This part of traditional replacing valve needs all to disintegrate after valve dismounting again, just can complete this work, whole steel disc district will be caused at least three hours to stop production, thus affect the whole production schedule of company, and bring about great losses; In addition, also need front and continued technique to stop before removing valve, could create the condition can removing valve, impact is normally produced.
Model utility content
In order to solve the problems of the technologies described above, the utility model aims to provide a kind of easy replacing and the tappet gear of abrasionproof.
The utility model is achieved by following technical solution:
A kind of easy replacing and the tappet gear of abrasionproof, comprise base, transmission nut, back-up ring, screw mandrel, handle, locking nut, set screw, bearing, described transmission nut is arranged in base, described screw mandrel is arranged in transmission nut, described back-up ring is arranged on base upper end, described handle is arranged on transmission nut and is but fixed by locking nut, described transmission nut is also provided with bearing and is but fixed on base by back-up ring.
Described transmission nut is provided with step in bearing bottom.
Described back-up ring is fixed on base by set screw.
The beneficial effects of the utility model are:
Compared with prior art, a kind of easy replacing that the utility model provides and the tappet gear of abrasionproof, install bearing by opening a groove on valve base, and on groove, add a back-up ring fixed conveyor nut slide up and down.Not only make valve be easy to when transmission nut damages change, the ball also making the frictional rotation of transmission nut become bearing rolls, and not only adds the working life of transmission nut, decreases the damage frequency of transmission nut, production is carried out smoothly.Also valve is made can not to affect production when changing transmission nut.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
In figure: 1-base, 2-transmission nut, 3-back-up ring, 4-screw mandrel, 5-handle, 6-locking nut, 7-set screw, 8-bearing.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but described in required protection domain is not limited to;
As shown in the figure, a kind of easy replacing that the utility model provides and the tappet gear of abrasionproof, comprise base 1, transmission nut 2, back-up ring 3, screw mandrel 4, handle 5, locking nut 6, set screw 7, bearing 8, described transmission nut 2 is arranged in base 1, described screw mandrel 4 is arranged in transmission nut 2, described back-up ring 3 is arranged on base 1 upper end, described handle 6 is arranged on transmission nut 2 and is but fixed by locking nut 6, described transmission nut 2 is also provided with bearing 8 and is but fixed on base 1 by back-up ring 3.Replace the wearing and tearing of transmission nut 2 by driving a groove installation bearing 8 on valve base 1, and on base 1 groove, add a back-up ring 7 to replace the boss on original transmission nut to prevent transmission nut 2 lower slider.Not only make valve be easy to when transmission nut damages change, the ball also making the frictional rotation of transmission nut become bearing rolls, and not only adds the working life of transmission nut, decreases the damage frequency of transmission nut, production is carried out smoothly.Also valve is made can not to affect production when changing transmission nut.
Described transmission nut 2 is provided with step in bearing 8 bottom.Prevent transmission nut 2 from sliding up and down for coordinating with bearing 8.
Described back-up ring 3 is fixed on base 1 by set screw 7.Be screwed, be easy to the replacing of transmission nut 2.
In the groove of described bearing 8 base 1 upper end.Instead of the sliding friction of transmission nut 2.
Claims (4)
1. easily change and the tappet gear of abrasionproof for one kind, comprise base (1), transmission nut (2), back-up ring (3), screw mandrel (4), handle (5), locking nut (6), set screw (7), bearing (8), described transmission nut (2) is arranged in base (1), described screw mandrel (4) is arranged in transmission nut (2), described back-up ring (3) is arranged on base (1) upper end, described handle (6) is arranged on transmission nut (2) and is but fixed by locking nut (6), it is characterized in that: described transmission nut (2) is also provided with bearing (8) and is but fixed on base (1) by back-up ring (3).
