Description
Technical field
The utility model relates to revolution actuation techniques field, more particularly, relates to a kind of revolution driving and uses worm screw.
Background technique
Worm and gear device for revolving and driving is a kind of novel revolution series products, is usually made up of worm screw, worm-gear type pivoting support, housing, power source etc., can bears axial force, radial force and tilting moment simultaneously.Compared with traditional revolution series products, worm and gear device for revolving and driving has owing to adopting worm drive that velocity ratio is large, work is comparatively stable, noise is low, compact structure, can the feature such as self-locking, therefore the engineering machinery field that it is widely used in high-altitude operation vehicle, truck crane etc. is representative, with the new energy field that solar energy power generating, wind-power electricity generation are representative, and the field such as other automations, Machine Manufacture, space flight communication.
In Worm Wheel System process, engagement between worm and wheel produces axial force to worm screw, when bearing load is larger, pressure between engaging tooth on worm screw and turbine and frictional force also larger, make worm gear and worm screw wearing and tearing, cause transmission unstable, transmission accuracy declines, and can not meet processing request.
At present, in prior art, adopt reduces the heating in use of the worm and gear flank of tooth and wear phenomenon by outside oil nozzle to the mode of worm and gear flank engagement place charging-up lubricant oil more, but because housing seal is bad, the phenomenon of easy generation oil leak, therefore, need to use lubricating grease to lubricate to replace lubricant oil worm and gear mesh tooth face, but during by outside oil nozzle grease up, because the mobility of lubricating grease is poor, not easily be filled into worm tooth-surface working position, abundant lubricating grease of must annotating just can make a small amount of lubricating grease arrive and need lubricant housings, can not arrive even completely and need lubricant housings, and the contact of the worm and gear flank of tooth and lubricating grease is insufficient, thus lubrication effect is reduced greatly, the lubricating grease of filling can not be fully used, cause the wasting of resources.
Through retrieval, existing relevant open about the patent report improving worm and gear engagement place lubrication effect.
Chinese Patent Application No.: 2004100223788.4, the applying date: on 04 05th, 2014, invention and created name is: worm and gear, this application case discloses a kind of worm-and-wheel gear, its by worm tooth, process through hole oil duct and on the worm gear flank of tooth processing oil groove, the lubricant oil in oil sump is enable to enter oil groove on the inner and worm gear flank of tooth of Worm Wheel System rubbing surface, thus the lubrication that improve to a certain extent Worm Wheel System rubbing surface inside, reduce the wearing and tearing of the worm and gear flank of tooth, but on the non-rubbing surface being located at worm tooth respectively due to filler opening and the oil outlet of the through hole oil duct on worm tooth in this application case and rubbing surface, and the oil duct through hole between filler opening and oil outlet is positioned at worm tooth inside, considerably increase the difficulty of processing, and the intensity of worm tooth is decreased, meanwhile, the filler opening in this application case can not make lubricant oil enter oil duct through hole timely and effectively, and especially when using lubricating grease to lubricate, effect is poorer.In addition, the processing of oil groove in this application case, on the worm gear flank of tooth, needs on each flank of tooth, all process the lubrication effect of oil groove guarantee to all teeth, but due to the number of teeth of worm gear relatively many, thus processing is comparatively bothered, working strength is larger.
