Abstract
An anti-oil dripping gear lubricating device comprises a gear shaft and a gear shaft sleeve, wherein the gear shaft is provided with a lubricating oil inlet; a longitudinal blind slot is formed on the outer surface of the gear shaft; and the lubricating oil inlet is communicated with the longitudinal blind slot through an oil supply channel opened inside the gear shaft. The gear lubricating device is further provided with an elastic oil-absorbing gear and a rigid gear sleeved on the gear shaft sleeve and longitudinally distributed at intervals; Y-shaped oil delivery slots leading to gear holes from two tooth sides respectively are formed on all teeth of the rigid gear which is in contact with the elastic oil-absorbing gear; through holes communicated with the Y-shaped oil delivery slots are formed on the gear shaft sleeve; and the circumference formed by rotating the through holes of the gear shaft sleeve around the gear shaft for a circle intersects with the longitudinal blind slot of the gear shaft. When the outer tooth part of the elastic oil-absorbing gear is in contact with a main gear under stress, lubricating oil in the elastic oil-absorbing gear is squeezed out, so that the function of lubricating the main gear is fulfilled; and when the outer tooth part of the elastic oil-absorbing gear is not under stress, redundant lubricating oil is absorbed through the elastic oil-absorbing gear, so that the oil preserving function is fulfilled.
Description
Technical field
The utility model relates to a kind of gear lubrication device of anti-oil dripping, mainly is applicable to wind turbine, and the gear lubrication of metallurgy, boats and ships, large-scale engineering machinery equipment belongs to the gear lubrication technical field.
Background technique
Gear is used widely as a kind of common driving parts.As everyone knows, the transmission between the gear must be lubricated by means of oiling agent, otherwise gear will damage influence production rapidly.
Along with the birth of this product of oilgear, tradition is substituted by the mode of artificial brush lubricant oil, and the self oiling problem of master gear has obtained good solution.This oilgear and gear are provided with the lubricant oil inlet opening in the skidding gear shaft, the outer toothed portion of oilgear has lubricating oil outlet, and lubricant oil inlet opening and lubricant outlet UNICOM have realized the conveying of lubricant oil.During work, inject lubricant oil inlet opening lubricant oil and flow out, spatter on master gear, realize lubricating master gear from lubricating oil outlet.This oilgear is generally by the pure metal manufacturing; because the pure metal gear can not tempered oil film when break-in; when oil starvation, can not play lubrication; and oil causes water clock too much the time easily; waste lubricant oil and befouling environment; promptly use container to collect, the lubricant oil after the collection also can't reuse owing to sneaked into dust.Also have a kind of gear mark to be wrapped with the oilgear of wool felt at present, wool felt can be drawn unnecessary lubricant oil, but its working life is short, has only about 2 years.
Summary of the invention
The purpose of this utility model is: at the oilgear short main deficiency in working life of above existing wool felt formula, a kind of gear lubrication device of anti-oil dripping is proposed, and long service life, and using effect is good.
In order to reach the above object: the gear lubrication device of a kind of anti-oil dripping of the utility model, its composition comprises gear shaft, gear bush, described gear shaft is provided with the lubricant oil inlet opening, the outer surface of gear shaft has a vertical blind groove, the oil feeding line UNICOM that offers by gear shaft inside between described lubricant oil inlet opening and the vertical blind groove, in addition, it also has and is sleeved on the gear bush and elasticity oil suction gear that longitudinal separation distributes, rigid gear, each tooth of rigid gear that contacts with described elasticity oil suction gear has the Y shape input oil groove of being led to gear hole by two flanks respectively, this Y shape input oil groove is as the lubricant oil oil outlet, offer the through hole with this Y shape input oil groove UNICOM on the described gear bush, the through hole of described gear bush intersects around the rotate a circle circumference that streaked and the vertical blind groove of gear shaft of gear shaft.
The beneficial effects of the utility model are as follows: the gear lubrication device of this anti-oil dripping is provided with distinctive oil duct, lubricant oil is delivered in the elasticity oil suction gear from the lubricant oil inlet opening of gear shaft, in the gear rotation process, when the outer toothed portion of elasticity oil suction gear contacts with master gear when being stressed, lubricant oil in the elasticity oil suction gear is extruded, and has played the effect of lubricated master gear; When the outer toothed portion of elasticity oil suction gear did not stress, unnecessary lubricant oil was sucked back by elasticity oil suction gear, had played the oil effect of protecting.
