Abstract
The utility model provides a stepped turning arc lapping joint piston ring, which solves the prior technical problems that the lapping joints at the two ends of the piston ring performs a complementary type stepped structure, the turnings of the stepped structure are vertical angles with low hardness, easy folding and loose seal. The utility model is characterized in that the turnings of the stepped structure are complementary type arcs. As an active result, the utility model keeps the advantage of the prior technique that the joint of the ring is not easy to run out for the complementary type stepped structure, meanwhile, the arc turnings of the stepped structure greatly increases the hardness, avoids the shortage of the easy folding, and finally improves the durability of the piston ring.
Description
Technical field
The utility model relates to the piston ring that seals between motor car engine upper piston and cylinder, particularly a kind of gap piston ring of taking.
Background technique
Piston ring is very crucial parts on the motor, and it is arranged between motor car engine piston and the cylinder, seals.If poorly sealed, will cause the cylinder pressure deficiency, reduce engine power, it is insufficient to burn, over-emitting black exhaust.Present piston ring has a collar extension, when engine operation, and piston ring expanded by heating, collar extension closure.But with after having spent a period of time, along with cylinder liner and wear of piston-rings, collar extension increases, and flexibility decrease, and collar extension can not be closed, poorly sealed phenomenon occurs.
People release a kind of gap piston ring of taking again for this reason, and the lapping mouth at two ends, this piston ring collar extension place is the stepped shaft of compensation each other, make collar extension be difficult for throwing off, and have prolonged the working life of piston ring.But because the turning of ladder is the right angle, intensity is low, and is easy to break, causes working life short.
Summary of the invention
The purpose of this utility model is to provide the turning of a species stage to be the gap piston ring of taking of circular arc.
The purpose of this utility model is achieved in that it has piston ring, and the lapping mouth at its collar extension place is the stepped shaft of compensation each other, it is characterized in that: the turning of said ladder is the circular arc of compensation each other.
The utility model is compared with the prior art scheme, and it has kept the ladder-type structure of compensation each other, and then has kept the difficult advantage of throwing off of collar extension, simultaneously because the ladder turning is the circular arc of compensation each other, so intensity improves widely, avoided defective easy to break, improved reliability.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is a schematic representation of the present utility model.
Embodiment
The lapping mouth at two ends, piston ring collar extension place is the stepped shaft of compensation each other, and the turning 1 of said ladder is the circular arc of compensation each other, and the radius of circular arc can be adjusted.
