Abstract
The invention relates to pistons, in particular to a lubrication groove type piston. The lubrication groove type piston comprises a piston and an oil ring; the oil ring is arranged at an upper part of the piston; a lubrication groove is arranged at a skirt part of the piston; and the lubrication groove is communicated with the oil ring through a groove. When the piston provided by the invention is used, lubrication oil in the lubrication groove can be used for sufficiently lubricating friction parts between the piston and the internal wall of a cylinder, so that the efficiency of engines is increased, the failure rate is lowered, and the cost is saved.
Description
Technical field
The present invention relates to a kind of piston, especially a kind of lubricated slot type piston.
Background technique
Former piston face and cylinder inner wall friction can produce high heat, piston easy deformation in this environment, and the skirt section produces expands, and occurs pull-cylinder phenomena easily, reduces the power of motor.
Summary of the invention
In order to overcome the deficiency of piston and cylinder friction part poor lubrication, the invention provides a kind of lubricated slot type piston.
The technical solution adopted for the present invention to solve the technical problems is: a kind of lubricated slot type piston, comprise piston and oil ring, and piston top is provided with oil ring, and the piston skirt is provided with lubrication groove, and lubrication groove is communicated with oil ring is fluted.
The invention has the beneficial effects as follows: use this piston can utilize the lubricant oil in the lubrication groove, the friction position of piston and cylinder inner wall is carried out lubricating fully, improve the efficient of motor, reduce rate of fault, practiced thrift cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a schematic representation of the present invention;
1. pistons among the figure, 2. oil ring, 3. lubrication groove.
Embodiment
Combine accompanying drawing that the present invention is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
Like Fig. 1 is structural representation of the present invention, and a kind of lubricated slot type piston comprises piston 1 and oil ring 2, and piston 1 top is provided with oil ring 2, and piston 1 skirt section is provided with lubrication groove 3, lubrication groove 3 and 2 fluted connections of oil ring.
During work, the lubricant oil in oil ring 2 grooves can enter in the lubrication groove 3 via connectivity slot, when piston 1 moves back and forth in cylinder; Lubricant oil on the lubrication groove just can be lubricated the contact position of piston 1 with cylinder; Use this piston can utilize the lubricant oil in the lubrication groove, the friction position of piston and cylinder inner wall is carried out lubricating fully, improve the efficient of motor; Reduce rate of fault, practiced thrift cost.
