Abstract
The invention discloses a steel crown and aluminium skirt piston, which comprises a piston crown (1), a piston skirt (2), a press block (4) and sleeves (6). The piston crown (1) and the piston skirt (2) are fastened by the press block (4) through a bolt (3) of a piston crown (2), and the sleeves (6) are arranged on the bolt (3) and the press cake (4). The steel crown and aluminium skirt piston replaces the full aluminum piston in same specification, so that the cost is lower and the strength is higher, and the steel crown and aluminium skirt piston can work continuously under heavy oil combusting environments at high explosion pressure.
Description
Technical field
The present invention relates to a kind of steel crown and aluminum skirt piston.
Background technique
Small dimension piston of the prior art mostly is full aluminium piston, and this piston cost is higher, and intensity is lower, can not satisfy the requirement of continuous operation under the environment of burning heavy oil, high pressure of explosion.
Summary of the invention
The purpose of this invention is to provide a kind of with low cost, steel crown and aluminum skirt piston that intensity is high.
The technological scheme that the present invention adopts for achieving the above object is: a kind of steel crown and aluminum skirt piston, comprise piston top (1), piston skirt (2), briquetting (4) and lining (6), tightly, described lining (6) is arranged on bolt (3) and the briquetting (4) bolt (3) by piston top (2) self between described piston top (1) and the piston skirt (2) with briquetting (4).
Described piston top (1) and piston skirt (2) are connected with elastic cylindrical pin (5).
Be provided with O RunddichtringO (7) between described piston top (1) and the piston skirt (2).
A kind of steel crown and aluminum skirt piston of the present invention has replaced the full aluminium piston of small dimension, makes cost cheaper, and intensity is higher, can continuous operation under the environment of burning heavy oil, high pressure of explosion.
Description of drawings
Fig. 1 is the structural representation of a kind of steel crown and aluminum skirt piston of the present invention.
Among the figure: 1, piston top; 2, piston skirt; 3, bolt; 4, briquetting; 5, elastic cylindrical pin; 6, lining; 7, O RunddichtringO.
Embodiment
As shown in Figure 1, steel crown and aluminum skirt piston, comprise piston top 1, piston skirt 2, briquetting 4 and lining 6, bolt 3 usefulness briquettings 4 by piston top 2 self between piston top 1 and the piston skirt 2 are tightly, lining 6 is arranged on bolt 3 and the briquetting 4, piston top 1 and piston skirt 2 are connected with elastic cylindrical pin 5, be provided with O RunddichtringO 7 between piston top 1 and the piston skirt 2, steel crown and aluminum skirt piston of the present invention, the full aluminium piston that has replaced small dimension, make cost cheaper, intensity is higher, can continuous operation under the environment of burning heavy oil, high pressure of explosion.
