Abstract
The utility model relates to the technical field of engines, particularly to a valve tappet, and aims to overcome the defects that friction between valve tappets and other components of engines is large and the mechanical loss is large in the prior art. The technical scheme includes that the valve tappet comprises a valve tappet body, an antifriction device is arranged on the lower portion of the valve tappet body, the valve tappet body is provided with an oil guide hole and an oil return hole, the antifriction device is connected with the valve tappet body through threads, and the antifriction device is made of a cemented carbide. The valve tappet has the advantages that the antifriction device made of the cemented carbide is installed on the lower portion of the valve tappet body, so that damage to the valve tappet due to friction in use can be reduced, performances of the valve tappet can be improved effectively, the antifriction device and the valve tappet body are connected through the threads, and the replacement of the antifriction device is facilitated.
Description
Technical field
The utility model relates to technical field of engines, relates in particular to a kind of valve tappet.
Background technique
Valve tappet is an important spare part in the engine air distribution system, and in engine working process, whether it moves, rotates flexible, can influence the performance of motor to a certain extent.Common valve tappet has straight tubular, waisting shape etc., and at least one oil guiding hole, a spill port are arranged on the valve tappet of every kind of shape.The working state of valve tappet is for moving up and down and rotating, and stressed is the force of sliding friction of tappet and guide wall.Move whether flexible, with area of contact size and lubricated whether much relations arranged fully.Straight tubular tappet, area of contact is big, and is lubricated also least sufficient.Waisting shape tappet surface of contact and lubricated also undesirable.In addition, in engine valve actuating mechanism, the wearing and tearing of camshaft and valve tappet body end face are to influence engine performance.
The model utility content
Technical problem to be solved in the utility model provides that a kind of to overcome in the prior art valve tappet and motor miscellaneous part frictional force big, a kind of valve tappet of the defective that mechanical loss is big.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of valve tappet, comprise the valve tappet body, and the bottom of described valve tappet body is provided with wear-resistant device, and described valve tappet body is provided with oil guiding hole and spill port.
Further, described wear-resistant device and valve tappet body are by being threaded.
Further, described wear-resistant device is cemented carbide.
The beneficial effects of the utility model are: be the wear-resistant device of cemented carbide at the bottom of valve tappet body mounting material, can reduce the infringement that valve tappet in use produces because of friction, improve the performance of valve tappet effectively, use be threaded wear-resistant device and valve tappet body, the replacing of convenient wear-resistant device.Description of drawings
Fig. 1 is the utility model structural representation.
In the accompanying drawing, the list of parts of each label representative is as follows:
1, valve tappet body, 2, wear-resistant device, 3, screw thread, 4, oil guiding hole, 5, spill port.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not for limiting scope of the present utility model.
Fig. 1 is a kind of embodiment of the present utility model, as shown in FIG., a kind of valve tappet, comprise valve tappet body 1, the bottom of valve tappet body 1 is provided with wear-resistant device 2, valve tappet body 1 is provided with oil guiding hole 4 and spill port 5, and wear-resistant device 2 is connected by screw thread 3 with valve tappet body 1, and wear-resistant device 2 is cemented carbide.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
