Abstract
The utility model provides a piston ring for an elevator buffer, and relates to the technical field of hydraulic buffers. The piston ring for the elevator buffer comprises a piston ring body which is a circular ring provided with a notch. The piston ring for the elevator buffer is characterized in that material of the piston ring body is spheroidal graphite cast iron. The piston ring for the elevator buffer is simple in structure and is made of the spheroidal graphite cast iron, thereby being capable of saving cost, resistant to abrasion, long in service life, energy-saving, environment-friendly, and easy to process.
Description
Technical field:
The utility model relates to the hydraulic bjuffer technical field, relates in particular to the buffer of elevator piston ring.
Background technique:
Piston ring is widely used on the various dynamic power machines, such as steamer, diesel engine, petrol engine, compressor, hydraulic press etc., is widely used in automobile, train, steamer, yacht etc.General piston ring is installed in the annular groove of piston, and it forms the chamber acting with elements such as piston, cylinder sleeve, cylinder caps, and preferably wear resistance need to be arranged.In the prior art, the piston ring that buffer of elevator is used all is to be manufactured by bronze material, and weight is heavier, and price is also relatively more expensive, and not wear-resisting, working life is low.
The model utility content:
Technical problem to be solved in the utility model is to overcome the defective of prior art, provides that a kind of cost is low, wear-resisting, long service life, the buffer of elevator piston ring that is easy to process.
Technical problem to be solved in the utility model realizes by the following technical solutions.
The buffer of elevator piston ring comprises piston ring body, and described piston ring body is the annulus that a breach is arranged, and it is characterized in that: the material of described piston ring body is magnesium iron.
The cross section of described piston ring body be shaped as rectangle or circle.
The beneficial effects of the utility model are: the utility model is simple in structure, uses magnesium iron as making material, can save cost, long, energy-conserving and environment-protective friction durability, and be easy to processing.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the buffer of elevator piston ring comprises piston ring body, and piston ring body 1 is for there being the annulus of a breach 2, and the material of piston ring body 1 is magnesium iron.The cross section of piston ring body 1 be shaped as rectangle.
The yield strength of magnesium iron is higher, is about the 0.7-0.8 of tensile strength.The yield strength of general cast steel is lower than this value with the ratio of tensile strength.This is an extremely valuable performance of magnesium iron.Practice is proof also, and magnesium iron is a kind of good high-abrasive material, and its wear-resisting property is better than gray cast iron and structural carbon steel.Therefore be suitable for making the parts easy to wear such as cylinder block, piston, bent axle, gear and bed piece.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. the buffer of elevator piston ring comprises piston ring body, and described piston ring body is the annulus that a breach is arranged, and it is characterized in that: the material of described piston ring body is magnesium iron.
