Abstract
The utility model provides a speed reducer sealing device for an extension machine and relates to the field of seamless steel tube production. The speed reducer sealing device is aimed at reducing oil leakage of a peed reducer and solves the problem that a main shaft of the speed reducer is easy to wear. A speed reducer main shaft of the speed reducer sealing device is provided with a seal ring, which is a double-strap seal ring; and a main shaft sleeve of the speed reducer sealing device is provided with seal ring grooves. With both seal ring grooves provided with seal ring straps, the speed reducer sealing device realizes commendable sealing between the main shaft and the speed reducer and thus realizes low leakage of thin oil. The speed reducer sealing device for the extension machine prevents large oil leakage at a shaft end, solves the problem that the main shaft of the speed reducer is easy to wear, and improves production capacity.
Description
Technical field
The utility model relates to the seamless steel tube production field, is specifically related to a kind of elongator reducer sealing device.
Background technique
In the seamless steel tube production field, the elongator speed reducer is to provide power by elongator master motor, through speed reducer speed drop is got off, and reaches the elongator roll by connecting rod again, carries out steel pipe rolling.
In the prior art, stressed bigger because of speed reducer is the equipment of a transferring power, need be equipment lubrication with thin oil, and, reduce wear for the equipment cooling.Cause waste and pollution for preventing that oil from leaking from the speed reducer main shaft, original equipment adds seal ring one at the speed reducer spindle nose, because of the speed reducer main shaft rotatablely moves always, seal ring damages easily, causes oil leakage phenomenon, it is many that oil reduces, will have influence on the lubricated of speed reducer, can cause that equally also the speed reducer temperature rises, temperature and the lubricated wearing and tearing that can be directed at equipment increase the weight of, influence the normal operation of equipment, production can not normally be carried out.
The model utility content
The purpose of this utility model is to reduce the speed reducer leakage of oil, has solved speed reducer main shaft problem easy to wear.
Speed reducer main shaft in the utility model is provided with seal ring, and seal ring is the double sealing circle.
Main shaft sleeve of the present utility model is provided with seal groove.
Advantage of the present utility model is that the phenomenon of a large amount of leakage of oils of axle head did not occur, and has solved speed reducer main shaft problem easy to wear, has improved yielding capacity.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the integrally-built plan view of speed reducer part on the elongator;
Fig. 2 is a speed reducer main-axis end part partial sectional view.
Embodiment
Speed reducer main shaft of the present utility model is provided with seal ring 2, and seal ring 2 is the double sealing circle.
During work, be provided with seal ring 2 in the two seals groove 4 separately, good sealing is arranged between main shaft 3 and speed reducer like this, the thin oil leakage rate is low.
Claims (2)
1. elongator reducer sealing device, the speed reducer main shaft is provided with seal ring, it is characterized in that: described seal ring (2) is the double sealing circle.
2. according to the described a kind of elongator reducer sealing device of claim 1, it is characterized in that: described main shaft sleeve (1) is provided with seal groove (4).
