Detailed description of the invention
For making this utility model solve the technical problem that, the technical scheme that adopts and the technique effect that reaches clearly, by the following technical solutions:
Referring to figs. 2 to Fig. 3, the roller shaft of a kind of rocker arrangement that first embodiment of the present utility model provides, the first oil groove 2 is offered in the side of the cylinder of columned roller shaft 1, and the first oil groove 2 connects with the arrival end 4 of the main oil gallery 3 of roller shaft 1 inner chamber. By offering the first oil groove 2, in roller shaft 1 assembling process, it is only necessary to the first oil groove 2 and the hole conducting carrying lubricating oil, the arrival end 4 of the main oil gallery 3 being not required in roller shaft 1 and the hole of conveying lubricating oil are fully aligned, assembly difficulty is substantially reduced, easy to assembly.
Preferably, the first oil groove 2 is parallel to the bottom surface of roller shaft 1. , in the process of assembling roller shaft 1, there is a small amount of rotating it is also possible that the first oil groove 2 connects with the hole of conveying lubricating oil the parallel bottom surface with roller shaft 1 of first oil groove 2, does not affect the oil-feed of roller shaft.
Preferably, with Fig. 2 for reference, the area of the first oil groove 2 is 1.1-10 times of the sectional area of arrival end 4. The Area comparison of the first oil groove 2 is big, and in the process of assembling roller shaft 1, error allows relatively larger, it is possible to greatly reduce assembly difficulty, guarantees that lubrication is good simultaneously.
For making lubrication between roller shaft 1 and the roller being assemblied on roller shaft 1 good, in the present embodiment, the second oil groove 5 is offered in the side of roller shaft 1, and the second oil groove 5 connects with the port of export 6 of the main oil gallery 3 of roller shaft 1 inner chamber. Second oil groove 5 increases the area of the port of export 6 so that between roller shaft 1 and roller, fuel-displaced area increases, and can lubricate better. Preferably, the second oil groove 5 is offered along the axial direction of roller shaft 1. The lubricating oil the second oil groove 5 by axial direction offering, the fuel-displaced area at axial direction becomes big, and lubricant effect is better. Preferably, with Fig. 2 for reference direction, the area of the second oil groove 2 is 1.1-10 times of the sectional area of the port of export 6. The Area comparison of the second oil groove 5 is big, can lubricate better.
In the present embodiment, roller shaft 1 is the roller shaft of SKD11 steel. SKD11 steel is the general cold work die steel of high abrasion toughness, function admirable, adopts the wearability of the roller shaft 1 of this material and load to disclosure satisfy that and use in methane fuelled engine.
In the present embodiment, roller shaft 1 is the roller shaft of hardness HRC60-62. The anti-wear performance of the roller shaft of hardness HRC60-62 is greatly enhanced, it is possible to meet needs.
In the present embodiment, main oil gallery 3 diameter of roller shaft 1 is not less than 2mm, it is furthermore preferred that the diameter of main oil gallery 3 is 3mm. After the enlarged-diameter of main oil gallery 3, oil circuit is smooth and easy, and oil pump capacity is big, and greasy property is good.
In the present embodiment, for making roller shaft 1 accurate positioning, roller shaft 1 being provided with hole 7, location, hole 7, location is assembled by pin.
Of the present utility model second embodiment provide a kind of rocker arrangement, including on roller shaft. Its roller shaft is easy to assembly.
A kind of electromotor that 3rd embodiment of the present utility model provides, including above-mentioned rocker arrangement, its roller shaft is easy to assembly.
