Abstract
The utility model relates to a driven gear and a driving gear which are used for the field of mechanical transmission. The utility model is provided with a lubricant passage, and uses the rotary force to directly inject the lubricant to the inner side of the friction surface of the driven gear and the driving gear so as to cause the friction surface to be sufficiently lubricated by the lubricant.
Description
Affiliated technical field:
The utility model relates to mechanical transmission, especially is the transmission lubrication of various flute profile wheels, axle, comprises straight-tooth, helical teeth, herringbone tooth, camber tooth (spiroid) worm and gear, axle and bearing shell etc.
Background technique
At present, known gear lubrication mainly is that oil sump is lubricated.Lubricate the lubricated of the active flank of tooth and driven gear tooth friction by the oil of being stained with on the band gear rubbing surface, so the lubricant oil of rubbing surface inside very little.Big to, rubbing surface big with transfer motion power, the high speed rotating gear lubrication is extremely unbecoming, because of poor lubrication, abrasion is big, heat is big and reduce revolution or make the belt pulley transmission into.Restricted the application area of this drive technology.
Summary of the invention
In order to overcome the lubricated deficiency of existing gear transmission, the utility model provides a kind of and lubricant oil is injected the inner and pressure that can carry rubbing surface of rubbing surface is lubricated.Two rubbing surface inside of gear transmission obtain sufficient lubricating oil.Improve bearing capacity, the raising gear revolution of gear.
The technological scheme that its technical problem of solving the utility model adopts is: the mechanical transmission lubrication technique device, the metal object that axially rotates in oil sump through bearing and has oil outlet on the attrition surface of other object.Centrifugal force is lubricated.Tooth on the driven gear, it is young at non-rubbing surface to go into oilhole, fuel-displaced aperture greatly at rubbing surface, rotate through gear that oil enters cucurbit shape passage, passage tilts along rubbing surface, lubrication friction face, the prevention of cucurbit shape in large area flow backwards because of the rubbing surface reaction force makes the oil burst, it is fully strong lubricated that thereby oil produces at rubbing surface, the another side of friction has the groove of oil duct, oil storage, makes lubricant oil uninterrupted.Help the formation of oil film.The front that gear rotates steering gear is a non-rubbing surface, and the back side is that the oil duct of rubbing surface from non-rubbing surface before the tooth to rear flank claims through hole.Be created on the driving gear of worm and gear, camber tooth; Spur gear, helical gear, herringbone gear etc. are created on the driven gear.There is the oil pump oil hole at a worm screw and an axle center for the oil duct end, and are connected into and out of oilhole.Oil outlet is on rubbing surface, and the opening of oil inlet hole is located at non-rubbing surface and comprises the wide face of rim.Also can lubricating with axle and bearing shell.
The beneficial effects of the utility model are, lubricant oil is used in gear rubbing surface inside fully, and lubrication effect significantly improves, and reduce friction, improve working life, improve the gear revolution, improve bearing capacity, enlarged application area, and simple in structure, cost is low, and is easy to use.
Further specify below in conjunction with drawings and Examples.
Fig. 1 is that worm and gear is in conjunction with figure.
Fig. 2 is a worm and gear tooth part sectioned view.
Embodiment
Among the figure: 1 worm screw, the 2nd, the opening of worm tooth non-rubbing surface lubricating oil duct oil inlet hole, the 3rd, worm tooth rubbing surface lubricating oil duct is fuel-displaced, and the 4th, elongated oil groove on the worm-gear tooth rubbing surface, the 5th, the wide face of worm tooth rim, the 6th, worm and gear tooth lubricant oil cucurbit shape oil duct generalized section.The 7th, the oil duct oil inlet and outlet of oil pump oil hole communicates.The 8th, keyway.
Power rotates worm screw through worm screw (1) among Fig. 1 at key and keyway (8) cooperation, enters lubricant oil (2) at worm and gear non-rubbing surface oil duct filler opening in the rotation and also can inject lubricant oil by (7) with oil pump, uses bolt during use and seals in order to avoid leakage of oil.Through cucurbit shape oil duct shown in Figure 2 (6), make lubricant oil inject elongated oil groove (4) on the rubbing surface inside of worm gear and worm screw and the worm-gear tooth rubbing surface in worm tooth rubbing surface lubricating oil duct outlet (3).
