Abstract
The utility model discloses a bulldozer track axis pin. An oil storage hole is arranged in the axial center of the axis pin, an oil outlet hole is arranged in the radial center of the axis pin, one end of the oil outlet hole of the axis pin in radial position is processed by adding a mark, and the mark of the axis pin faces against a track plate when the track is to be installed. The bulldozer track axis pin has the advantages that grease can be stored inside the axis so that when the amount of grease between the axis pin and the track reduces, the grease inside the axis pin can flow to the space between the axis pin and a pin bush through the oil outlet hole, so that greasing time of the track is increased and service life of the track is prolonged.
Description
Technical field
The utility model relates to mechanical equipment technical field, specifically a kind of bulldozer crawler belt bearing pin.
Background technology
The service life of bulldozer crawler belt and the lubrication system of crawler belt have much relations, the bearing pin of existing bulldozer crawler belt is a circular shaft, can not store grease, only smear when mounted one deck grease, because the amount of grease is smaller, the time that crawler belt can lubricate is short, and the service life of crawler belt is not long.
The bearing pin of existing bulldozer crawler belt is a circular shaft, can not store grease, only smears when mounted one deck grease, because the amount of grease is smaller, the time that crawler belt can lubricate is short, and the service life of crawler belt is not long.
The utility model content
For above-mentioned technical matters, it is a kind of in order to improve the service life of crawler belt that the utility model provides, and designed a kind of crawler belt bearing pin that can storing lubricating grease.
The technical scheme that its technical matters that solves the utility model adopts is, this bulldozer crawler belt bearing pin, in the middle of bearing pin is axial, increase an oil storage hole, oil outlet of the radially middle increase of bearing pin, and at mark of an end of bearing pin oil outlet place radial position processing, the mark of bearing pin caterpillar block dorsad when crawler belt is installed.
The beneficial effect that the utility model produces is, can store grease in the bearing pin, when the grease in the middle of bearing pin and the guide reduced, the grease in the bearing pin can flow between bearing pin and the guide through oil outlet, prolong the lubrication time of crawler belt, increased the life-span of crawler belt.
Description of drawings
Be elaborated below in conjunction with the drawings and specific embodiments:
Fig. 1 is the utility model structural representation
Among the figure, 1, mark 2, oil outlet 3, oil storage hole
The specific embodiment
As shown in the figure, the utility model is a kind of bulldozer crawler belt bearing pin, increases an oil storage hole 3 in the middle of bearing pin is axial, oil outlet 2 of the radially middle increase of bearing pin, and at mark 1 of an end of bearing pin oil outlet place radial position processing, the mark 1 of bearing pin caterpillar block dorsad when crawler belt is installed.
The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
The technology that the utility model is not described in detail, shape, structure partly are known technology.
Claims (2)
1. a bulldozer crawler belt bearing pin is characterized in that, increases an oil storage hole in the middle of bearing pin is axial, oil outlet of the radially middle increase of bearing pin.
