Description
Technical field
The utility model relates to mechanical field, and relating in particular to one can auto-compensation associated sealing arrangement for bearings.
Background technique
Bearing is in mechanical transmission course, to work the parts of fixing and reducing load friction factor.Also can say, in the time that other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in power transmission process.Rolling bearing is that the sliding friction between the axle of running and axle bed is become to rolling friction, thereby reduces the mechanical component of a kind of precision of frictional loss.Rolling bearing is generally made up of inner ring, outer ring, rolling element and retainer four parts, and the effect of inner ring is to match to merge with axle to rotate together with the axis; Outer ring effect is to match with bearing support, plays a supportive role; Rolling element is uniformly rolling element to be distributed between inner ring and outer ring by means of retainer, and its shape size and quantity directly affect usability and the life-span of rolling bearing; Retainer can make rolling element be uniformly distributed, and prevents that rolling element from coming off, guiding rolling element rotation lubricate.
The object of bearing seal is to prevent leaking outside of lubricant oil in bearing portion, and prevents that the harmful objects such as outside dust, moisture, foreign matter from invading bearing inside, makes the bearing can be under desired cond, safety and lasting running.Machine Design middle (center) bearing cavity is commonly used oil lubrication and cooling, draws axle and need to prevent leakage of oil with seal ring, and high temperature lubricating oil seal mechanism has wolfram steel sealing.Although wolfram steel seal ring is durable in use, sealing effect is high, customize, difficult processing, and precision is high, cost costliness.Rubber seal is widely used, but antifriction not, and the time one is of a specified duration, and seal ring is aging and there is no automatic error compensation, adds oil pressure in upper impression high, just there will be oil leakage phenomenon.A large amount of waste lubricant oil, affects the normal work of machine, repairs trouble.
Model utility content
The utility model is in order to overcome deficiency of the prior art, provides the one can auto-compensation associated sealing arrangement for bearings.
The utility model is to be achieved through the following technical solutions:
One can auto-compensation associated sealing arrangement for bearings, comprise casing, be arranged on axle, jump ring on casing, be arranged on the bearing on casing, described bearing is fixed on casing by the jump ring being arranged in casing draw-in groove, be arranged on the end cap on casing end face, described end cap is fixedly connected with by countersunk screw with casing, one end of described end cap is connected with pressing plate, cylinder between described pressing plate and end cap is provided with spring, O type circle is housed in the bottom groove of described pressing plate, on axle between described pressing plate and end cap, be socketed with scraper ring, described scraper ring is provided with little spring outward.
As optimal technical scheme of the present utility model, the bottom section of described scraper ring is profile of tooth.
As optimal technical scheme of the present utility model, the described casing endoporus corresponding with pressing plate is taper.
As optimal technical scheme of the present utility model, described pressing plate bottom is provided with circular groove.
Compared with prior art, the beneficial effects of the utility model are: the utility model is reasonable in design, simple in structure, by pressing plate being produced to certain pretightening force, can effectively compensate the error that the phenomenon such as aging causes because long-time hot environment produces, the conical design of box body hole make inside radius reduce gradually sealing effect also better, take the seal approach of scraping ring for axle, sealing effect is better, reduce the possibility that lubricant oil leaks, reduced the impurity such as extraneous dust simultaneously and entered.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1-bearing; 2-casing; 3-O type circle; 4-end cap; 5-axle; 6-scraper ring; 7-little spring; 8-pressing plate; 9-jump ring; 40-countersunk screw; 80-spring.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described one can auto-compensation associated sealing arrangement for bearings, comprise casing 2, be arranged on the axle 5 on casing 2, jump ring 9, be arranged on the bearing 1 on casing 2, described bearing 1 is fixed on casing 2 by the jump ring 9 being arranged in casing 2 draw-in grooves, jump ring 9 makes installation simple in structure more convenient, be arranged on the end cap 4 on casing 2 end faces, described end cap 4 is fixedly connected with by countersunk screw 40 with casing 2, one end of described end cap 4 is connected with pressing plate 8, the cylinder at pressing plate 8 tops is arranged in the circular hole of end cap 4, ensure the positional accuracy of pressing plate 8, make pressing plate 8 stressed evenly, cylinder between described pressing plate 8 and end cap 4 is provided with spring 80, by the compression in advance for spring 80, make spring 80 produce certain pretightening force.
Described pressing plate 8 bottoms are provided with circular groove, O type circle 3 is housed in the bottom groove of described pressing plate 8, circular groove makes O type circle while easy for installation O type circle 3 in the fixed installation process of pressing plate 8 be not easy to relax, described casing 2 endoporus corresponding with pressing plate 8 is taper, and the characteristic that taper reduces gradually more easily reaches compensation sealing effect.On axle 5 between described pressing plate 8 and end cap 4, be socketed with scraper ring 6, described scraper ring 6 is outer is provided with little spring 7, and the bottom section of described scraper ring 6 is profile of tooth, and in the process of rotating at axle 5, area of contact is little, and the design of multilayer simultaneously makes again good sealing effect.The utility model is reasonable in design, simple in structure, by pressing plate being produced to certain pretightening force, can effectively compensate the error that the phenomenon such as aging causes because long-time hot environment produces, it is also better that the conical design of box body hole makes inside radius reduce gradually the effect of sealing, takes the seal approach of scraping ring for axle, and sealing effect is better, reduce the possibility that lubricant oil leaks, reduced the impurity such as extraneous dust simultaneously and entered.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
