Abstract
The utility model relates to a novel eccentric wheel gear. The novel eccentric wheel gear comprises a large gear and two eccentric wheels, wherein the two eccentric wheels are balanced and fixedly arranged on the two sides of the large gear, and the edges of the two eccentric wheels are provided with grease ports. The novel eccentric wheel gear provided by the utility model is characterized in that the two eccentric wheels are balanced and fixedly arranged on the two sides of the large gear, and the novel eccentric wheel gear is formed by integral forging; the intensity of the eccentric wheel gear is higher, the volume is reduced, the edges of the two eccentric wheels are provided with the grease ports, the weight of the eccentric wheels is lightened, lubricating grease is filled into the grease ports, a contacting surface of a connecting rod and the eccentric wheels are lubricated in a transmission process, and the attrition is lightened.
Description
Technical field
The utility model relates to a kind of Novel eccentric wheel gear.
Background technique
Eccentric effect generally has two: do cam or do crank.Two eccentric wheels of eccentric wheel gear of the prior art are in the same side of gearwheel, and gear and eccentric wheel are assembled together after will processing respectively again; Make the volume of whole eccentric wheel gear larger, requisite space is larger; In use, between general connecting rod tip and eccentric wheel, needle bearing or ball bearing are housed, making on eccentric wheel to have opening; Lubricating grease is difficult to enter between connecting rod tip and eccentric wheel and is lubricated in transmission process, and is if things go on like this more serious to the wearing and tearing of product, and because of fricative temperature higher.
The model utility content
The purpose of this utility model is to overcome the defective that prior art exists, and the Novel eccentric that a kind of volume is little, lightweight, intensity is high wheel gear is provided.
The technological scheme that realizes the utility model purpose is: a kind of Novel eccentric wheel gear comprises a gearwheel and two eccentric wheels; The balanced fixing opposed both sides at gearwheel of described two eccentric wheels; Described two eccentric edges all have a lubricating grease mouth.
All has the through hole that varies in size on the described gearwheel of technique scheme and two eccentric wheels.
The described eccentric wheel gear of technique scheme is integrated forging molding.
After adopting technique scheme, the utlity model has following positive effect:
(1) two eccentric wheels of the present utility model are balanced fixing opposed in the both sides of gearwheel, and the eccentric wheel gear is integrated forging molding; Make the eccentric wheel strength of gear teeth higher, volume-diminished.
(2) two eccentric edges of the present utility model all have a lubricating grease mouth, not only alleviated the weight of eccentric wheel gear, and lubricating grease is filled in the lubricating grease mouth, and well connecting rod and eccentric surface of contact are lubricated in transmission process, alleviate wearing and tearing.
(3) all have the through hole that varies in size on gearwheel of the present utility model and two eccentric wheels, alleviated the weight of eccentric wheel gear, more be conducive to the upper current downflow of lubricating grease.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model, wherein according to specific embodiment also by reference to the accompanying drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of the A-A direction of Fig. 1;
1. gearwheels in figure, 2. eccentric wheel, 21. lubricating grease mouth, 3. through holes.
Embodiment
(embodiment 1)
See Fig. 1 and Fig. 2, the utility model comprises a gearwheel 1 and two eccentric wheels 2; Opposed both sides at gearwheel 1 are fixed in two eccentric wheel 2 equilibriums; The edge of two eccentric wheels 2 all has a lubricating grease mouth 21; All have the through hole 3 that varies in size on gearwheel 1 and two eccentric wheels 2, the eccentric wheel gear is integrated forging molding; Not only alleviate the weight of eccentric wheel gear, and be conducive to flowing of lubricating grease, increased the intensity of eccentric wheel gear.
Above-described specific embodiment; the purpose of this utility model, technological scheme and beneficial effect are further described; institute is understood that; the above is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (3)
1. a Novel eccentric wheel gear, comprise a gearwheel (1) and two eccentric wheels (2); It is characterized in that: opposed both sides in gearwheel (1) are fixed in described two eccentric wheels (2) equilibrium; The edge of described two eccentric wheels (2) all has a lubricating grease mouth (21).
2. Novel eccentric wheel gear according to claim 1, is characterized in that: all have the through hole (3) that varies in size on described gearwheel (1) and two eccentric wheels (2).
