Description
technical field
The utility model relate to a kind of can the hydraulic turbine main shaft structure of automatic makeup fat.
Background technique
At present, adopt the mechanism of grease lubrication, generally inject with grease gun during supplemental lubrication fat, need long maintenance time, and the dress fat process ratio of grease gun is easier to cause surrounding environment to be infected with lubricating grease, be difficult to cleaning, safeguard inconvenience.
Model utility content
For overcoming above-mentioned deficiency, the utility model object be to provide a kind of can the hydraulic turbine main shaft structure of automatic makeup fat.
Scheme of the present utility model is as follows: the water turbine for cooling tower main shaft structure adopting grease lubrication, and comprise main shaft, bearing, bearing housing and gland, described bearing is divided into upper and lower bearing, and described gland is divided into upper and lower gland; The intermediate section two ends of described main shaft are socketed upper and lower bearing respectively, and described upper and lower bearing is arranged on the upper and lower end of bearing housing; Described bearing housing upper and lower end is also respectively arranged with upper and lower gland, is closed by the upper and lower end of bearing housing; Described upper press cover and bearing housing all offer a through tapped hole, mends fat tank and fixed by the outside thread of grease outlet and the screw-internal thread fit of tapped hole.
Described bearing housing both sides inwall is provided with concave station, and the protuberance at central diaphragm two ends coordinates with concave station; Described main shaft intermediate section is through central diaphragm and two ends pass upper and lower gland.
Further, described main shaft and upper press cover joint are provided with oil sealing.
Further, described main shaft and lower cover joint are provided with lower oil sealing.
Further, described lower oil sealing quantity is two.
Further, described central diaphragm and main shaft joint are provided with middle oil sealing.
Further, lubricating grease is filled with between described upper and lower bearing and central diaphragm.
The utility model is for the characteristic of water turbine low-speed running, and adopt the mode of grease lubrication to replace traditional oil lubrication water turbine for cooling tower to water turbine for cooling tower main shaft structure, the setting of upper and lower oil sealing can enter bearing housing by anti-sealing; Upper and lower gland anti-sealing, dust etc. can enter bearing housing; Middle oil sealing, together with central diaphragm, prevents the lubricating grease required for upper bearing (metal) from leaking downwards; Lower cover can prevent the lubricating grease required for lower bearing from leaking downwards; Lower oil sealing adopts dual-oil seal to ensure the sealing of lubricating grease further.
Benefit fat tank of the present utility model, slowly, uniformly can discharge lubricating grease in a long time, for bearing provides stable, reliable grease replenishing, extend the time lag of manual maintenance, and only need change when safeguarding with the fixing automatic makeup fat device of screw thread, it is very convenient to safeguard.
The utility model lubricates safety, reliably, not easily leaks, and improves the reliability of whole turbine equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Adopt the water turbine for cooling tower main shaft structure of grease lubrication, comprise main shaft 1, bearing, bearing housing 5 and gland, bearing is divided into 4, lower bearing 9, gland is divided into 3, lower cover 10; The intermediate section two ends of main shaft 1 are socketed upper and lower bearing 4,9 respectively, and upper and lower bearing 4,9 is arranged on the upper and lower end of bearing housing 5; Bearing housing 5 upper and lower end is also respectively arranged with upper and lower gland 3,10, is closed by the upper and lower end of bearing housing 5; Bearing housing 5 both sides inwall is provided with concave station, and the protuberance at central diaphragm 7 two ends coordinates with concave station; Main shaft 1 intermediate section is through central diaphragm 7 and two ends pass upper and lower gland 3,10.Upper press cover 10 and bearing housing all offer a through tapped hole, mends fat tank 12 and fixed by the outside thread of grease outlet and the screw-internal thread fit of tapped hole.
Main shaft and upper press cover joint are provided with oil sealing 2, and lower cover joint is provided with lower oil sealing 11, can enter bearing housing by anti-sealing, and lower oily 11 envelopes adopt dual-oil seal to ensure the sealing of lubricating grease further.Central diaphragm 7 and main shaft 1 joint are provided with middle oil sealing 8, and middle oil sealing, together with central diaphragm, prevents the lubricating grease required for upper bearing (metal) from leaking downwards.Be filled with lubricating grease between upper and lower bearing 4,9 and central diaphragm 7, provide lubrication to upper and lower bearing 4,9.
Benefit fat tank of the present utility model, slowly, uniformly can discharge lubricating grease in a long time, for bearing provides stable, reliable grease replenishing.
Although give detailed description and explanation to embodiment of the present utility model above; but what should indicate is; we can carry out various equivalence according to conception of the present utility model to above-mentioned mode of execution and change and amendment; its function produced do not exceed that specification contains yet spiritual time, all should within protection domain of the present utility model.
