Embodiment Construction

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them (for It is convenient to describe and understand, the following figure 1 above is described above). Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] see Figure 1-13 , the present invention provides a technical solution: a diesel engine roller tappet, including a body 1 and a bushing 5, the use of the bushing 5 avoids direct contact between the roller 4 and the positioning shaft 6, and prolongs the service life of the tappet body 2. The bushing 5 adopts a cylindrical hollow structure and is

Abstract

The invention discloses a diesel engine roller tappet. The diesel engine roller tappet comprises a machine body and a bush, wherein a tappet body is arranged in the machine body; a thrust block is arranged on the tappet body; the upper end of the thrust block abuts against a push rod; the thrust block is in interference fit with the tappet body; a roller is arranged on the outer side face of the bush; a rotating mechanism composed of the roller and the bush is fixedly connected with the tappet body through a positioning shaft; and one side of the positioning shaft is fixedly connected with thetappet body through a positioning screw. Vertical through holes are adopted in a first oil way and a second oil way of the diesel engine roller tappet, machining is simple, and the production cost issaved; a rectangular positioning boss at one end of the positioning shaft effectively prevents the tappet body from rotating in the working process, positioning is simple, and use is reliable; and the positioning shaft is positioned on the tappet body through the positioning screw, positioning is accurate and reliable, and the assembling accuracy is improved.
