Abstract
The utility model discloses a slewing bearing with oil drainage holes. The slewing bearing comprises an outer ring, an inner gear ring and a sealing belt, wherein a roller path is arranged between the outer ring and the inner gear ring, a plurality of roller path steel balls for separating the outer ring from the inner gear ring are arranged inside the roller path, a plurality of oil drainage holes are uniformly formed in the inner gear ring, and the outlets of the oil drainage holes are formed between tooth spaces of every two adjacent teeth on the inner gear ring. The certain oil drainage holes are additionally formed in the inner gear ring and are uniformly distributed in the gear circumference of the inner gear ring, residual grease accumulating in the roller path can be smoothly drained through the oil drainage holes, and the drained grease enters into the gear ring, so that not only is the problem of grease accumulation solved, but also the running gear can be lubricated in assistance, and the problem that grease cannot be added into the gear for lubrication in a later period is solved. According to the slewing bearing disclosed by the utility model, the grease is reasonably used, the tooth lubrication can be added, the possibility of lubricating the gear manually is reduced, and the problem that the grease cannot be added into the gear for lubrication in the later use period of the gear is solved.
Description
Technical field
The utility model relates to a kind of pivoting support, especially a kind of pivoting support with oil drainage hole.
Background technique
Pivoting support is a kind of large size bearing that can bear combined load, can bear simultaneously larger axially, radial load and tilting moment, in real industry, use very extensive, pivoting support needs to lubricate in the process of using, pivoting support in the past is the oil hole by the outer ring, regularly inject grease, reaching the purpose of lubricated raceway, but the grease that accumulates in the raceway still stay in the raceway, do not have stable discharge channel, can extrude by rubber seal on a small quantity, the problem that grease contamination occurs easily, row's fat be poor efficiency very also, and, the gear later stage can't increase lubricant oil, has increased certain difficulty and danger to maintenance.
The model utility content
In order to address the above problem, the utility model provides a kind of pivoting support that can get rid of the Novel belt oil drainage hole that the unnecessary grease that accumulates in the raceway and later stage can add lubricant oil.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
The utility model is a kind of pivoting support with oil drainage hole, pivoting support comprises outer ring and ring gear, between outer ring and ring gear raceway is arranged, and has several to separate the raceway steel ball of outer ring and ring gear in raceway, pivoting support also is provided with sealing strip, is provided with a plurality of oil drainage holes at ring gear.
Further improvement of the utility model is: the outlet of each oil drainage hole is separately positioned in the middle of the teeth groove of per two adjacent teeth on the ring gear.
The beneficial effects of the utility model are: by increase the oil drainage hole of some at ring gear, oil drainage hole is distributed on the circumference of gear of ring gear, the unnecessary grease that oil drainage hole accumulates in can smooth and easy discharge raceway, the grease of discharging enters gear surface, not only solve the problem that grease accumulates, the gear in all right lubrication assistant running; Solved also that the later stage can't add glossy problem on the gear.
The utility model rationally utilizes grease, and it is lubricated to increase tooth section, reduce the probability of artificial treatment gear lubrication problem, has solved gear and has used the later stage can't refuel the problem that stuffing is lubricated.
Description of drawings
Fig. 1 is section of structure of the present utility model.
Wherein: 1-outer ring, 2-sealing strip, 3-ring gear, 4-raceway steel ball, 5-oil drainage hole.
Embodiment
In order to deepen understanding of the present utility model, the utility model is done describing in further detail below in conjunction with drawings and Examples, this embodiment only is used for explaining the utility model, protection domain of the present utility model is not consisted of to limit.
As shown in Figure 1, the utility model is a kind of pivoting support with oil drainage hole, described pivoting support comprises outer ring 1 and ring gear 3, between described outer ring 1 and described ring gear 3, raceway is arranged, the raceway steel ball 4 that the described outer ring 1 of numerous separation and described ring gear 3 are arranged in described raceway, described pivoting support also is provided with sealing strip 2, on described ring gear 3, evenly be provided with a plurality of oil drainage holes 5, by increase the oil drainage hole of some at ring gear, oil drainage hole is evenly distributed on the circumference of gear of ring gear, the unnecessary grease that oil drainage hole accumulates in can smooth and easy discharge raceway, the grease of discharging enters gear ring, not only solve the problem that grease accumulates, the gear in all right lubrication assistant running; Solved also that the later stage can't add glossy problem on the gear, oil drainage hole is easy to realize in technique, simple in structure, behind the Gear Processing work step, carry out the location in raceway one side, specification according to designed oil drainage hole gets out oilhole, and the outlet of each described oil drainage hole 5 is separately positioned in the middle of the teeth groove of per two adjacent teeth on the described ring gear 3.
Embodiment: be the pivoting support design tooth section oil drainage hole of a raceway diameter more than 2.5 meters, product before has two shortcomings when lubricated, grease overflows and pollutes the outer ring, internal gear can't add lubricant oil in the running later stage, according to the gear situation, done the oil drainage hole design, the number of teeth is 120, design 15 oil drainage holes that diameter is φ 8, have one in the middle of per 8 teeth.The pivoting support that increases oil drainage hole has solved the shortcoming that grease overflows and the later stage can't be added lubricant oil.
The utility model rationally utilizes grease, and it is lubricated to increase tooth section, reduce the probability of artificial treatment gear lubrication problem, has solved gear and has used the later stage can't refuel the problem that stuffing is lubricated.
