Abstract
The utility model discloses a rolling wheel used on an automobile valve rocker arm. The rolling wheel comprises an outer ring (1) and a core shaft (2), wherein two ends of the core shaft (2) are fixedly connected with the valve rocker arm, the outer ring (1) is rotatably connected with the middle part of the core shaft (2); an axial blind hole (2.2) used for storing lubricating oil is formed in the core shaft (2), at least one radial oil charging hole (2.1) is formed in the core shaft (2) as well, one end of the radial oil charging hole (2.1) is communicated with the blind hole (2.2), and the other end of the radial oil charging hole (2.1) is communicated with a gap between the outer ring (1) and the core shaft (2). After adopting the structure disclosed by the utility model, the structure is simple, moreover, production procedures are reduced, and the operation is simple, so that the production efficiency is greatly improved; meanwhile, damage on the outer ring or the core shaft due to abrasion of roll balls is avoided, so that the service life of the rolling wheel is prolonged.
Description
Technical field
The utility model relates to the auto parts machinery technical field, is specifically a kind of for the roller on the automobile air valve rocking arm.
Background technique
The effect of valve on motor car engine is to be responsible for specially in motor to input fuel combustion gas, and the valve rocker relevant to valve is also important auto parts and components.One end and the valve of valve rocker offset, and the housing of the other end and motor offsets.Usually at an end of the valve rocker offseted with motor body, a roller can be installed, roller comprises mandrel and outer ring, for mandrel can be rotatably connected in outer ring more neatly, in prior art, there are two kinds of structures to realize, the first is driven circular groove radially on the inwall of outer ring, in circular groove, be covered with ball; It two is on the outer wall of mandrel, to drive circular groove radially, in circular groove, is covered with ball.But there is following shortcoming in the roller of above two kinds of structures: owing to driving circular groove and arranging ball, all increased production process, troublesome poeration, therefore, reduce manufacturing efficiency greatly; Simultaneously, bring larger damage on the contrary after the ball wearing and tearing mandrel and outer ring, thus reduction of service life.
The model utility content
Technical problem to be solved in the utility model is, provides a kind of simple in structure, processing and assembling simple, and guarantee working life for the roller on the automobile air valve rocking arm.
For solving the problems of the technologies described above, the utility model provide for the roller on the automobile air valve rocking arm, comprise outer ring and mandrel, the two ends of mandrel are fixedly connected with valve rocker, outer ring rotating is connected to mandrel middle part; In described mandrel, have axially be used to storing the blind hole of lubricant oil, in mandrel, also have at least one radially oil hole, an end of described radially oil hole is communicated with blind hole, and the other end communicates with the gap between mandrel with outer ring.
The quantity of described radially oil hole is three, in the circumferential direction of the circle uniform.
Blind hole open end close-fitting on described mandrel has end cap.
After adopting above structure, the utility model compared with prior art, have the following advantages: owing to adopting structure from lubricant oil to the gap between outer ring and mandrel that inject to replace processing circular groove of the prior art and arranging ball, not only simple in structure, but also reduced production process, simple to operate, therefore, greatly enhance productivity; Simultaneously, also avoid damage outer ring or mandrel brought because of the wearing and tearing of ball, thereby extended the working life of roller.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model for the roller on the automobile air valve rocking arm.
Wherein: 1, outer ring; 2, mandrel; 2.1, oil hole radially; 2.2, blind hole; 3, end cap.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As can be known for the structural representation of the roller on the automobile air valve rocking arm by the utility model shown in Figure 1, it comprises outer ring 1 and mandrel 2, and the two ends of mandrel 2 are fixedly connected with valve rocker, and outer ring 1 is rotatably connected on mandrel 2 middle parts.In described mandrel 2, have the axial blind hole 2.2 be used to storing lubricant oil, in mandrel 2, also have at least one radially oil hole 2.1, an end of described radially oil hole 2.1 is communicated with blind hole 2.2, and the other end communicates with the gap between mandrel 2 with outer ring 1.
The quantity of described radially oil hole 2.1 is three, in the circumferential direction of the circle uniform.
Blind hole 2.2 open end close-fittings on described mandrel 2 have end cap 3.
Claims (3)
1. one kind for the roller on the automobile air valve rocking arm, comprises outer ring (1) and mandrel (2), and the two ends of mandrel (2) are fixedly connected with valve rocker, and outer ring (1) is rotatably connected on mandrel (2) middle part; It is characterized in that: in described mandrel (2), have the axial blind hole (2.2) be used to storing lubricant oil, in mandrel (2), also has at least one radially oil hole (2.1), one end of described radially oil hole (2.1) is communicated with blind hole (2.2), and the other end communicates with the gap between mandrel (2) with outer ring (1).
2. according to claim 1 for the roller on the automobile air valve rocking arm, it is characterized in that: the quantity of described radially oil hole (2.1) is three, in the circumferential direction of the circle uniform.
