Abstract
A high-temperature wear-resistant cylinder structure comprises a cylinder and a piston. A cylinder inner sleeve is mounted on the inner wall of the cylinder and is in interference fit with the inner wall of the cylinder, the inner surface of the cylinder inner sleeve is in smoothing treatment, both the outer surface of the cylinder inner sleeve and the inner wall of the cylinder are in rubbing treatment so as to guarantee that the cylinder inner sleeve cannot slip from the cylinder after the cylinder inner sleeve is mounted in the cylinder, the piston is mounted in the cylinder inner sleeve, and the cylinder inner sleeve is arranged in regions, corresponding to an upper stop point and a lower stop point of the piston, on the inner wall of the cylinder. The high-temperature wear-resistant cylinder structure has the advantages that wear resistance of the cylinder at high temperature is realized creatively, the cylinder inner sleeve made of a high-temperature wear-resistant material is mounted between the cylinder and the piston, cost for the cylinder in casting and high-temperature wear-resistant treatment processes can be greatly lowered, and wear resistance of the cylinder at the high temperature can be enhanced.
Description
Technical field
The present invention relates to a kind of high-temperature wearable air cylinder structure, belong to the power system engine art.
Background technique
The common cylinder piston structure of engine art all is that cylinder is become Spielpassung with plunger designs at present, between cylinder and piston, is provided with seal ring and carries out slipper seal.
Such structure has proposed higher requirement to cylinder, and particularly the inwall of cylinder also will polish smooth inwall later at the cylinder casting, and will carry out the process treating of its high-temperature wearables of raising such as carburizing, so the manufacture cost of cylinder is higher.
Summary of the invention
The objective of the invention is a kind of cylinder inner wall problem high, a kind of high-temperature wearable air cylinder structure is provided the heat resistant and wear resistant performance requirement.
The objective of the invention is to realize through following technological scheme:
The high-temperature wearable air cylinder structure comprises cylinder and piston, at the inwall of said cylinder one gas inner cylinder sleeve is installed; Adopt interference fit between said gas inner cylinder sleeve and the cylinder inner wall, be in more than 300 ℃ in the high temperature, will be in the cylinder of normal temperature state cover and pack in the cylinder at cylinder; The thickness of said gas inner cylinder sleeve is 3-5mm; Said gas inner cylinder sleeve adopts high-temperature and wear-proof to process, and the internal surface of gas inner cylinder sleeve is through smooth treatment, and the outer surface of gas inner cylinder sleeve and said cylinder inner wall all adopt friction treatment; After guaranteeing that the gas inner cylinder sleeve is installed in cylinder interior; The gas inner cylinder sleeve can slippage from cylinder, and said piston is installed in the said gas inner cylinder sleeve, and the pairing cylinder inner wall of the top dead center of piston and lower dead center all has the gas inner cylinder sleeve in the zone.
The invention has the beneficial effects as follows; The creationary cylinder wear-resisting problem under the high temperature condition that solved; The gas inner cylinder sleeve of processing through the high-temperature and wear-proof of between cylinder and piston, packing into; The cost of cylinder in casting and high-temperature wearable processing procedure can be reduced greatly, cylinder wear-resisting performance under high temperature condition can be improved.
Description of drawings
According to accompanying drawing and embodiment the present invention is done further explain below.
Fig. 1 is the structural drawing of the described high-temperature wearable air cylinder structure of the embodiment of the invention.
Embodiment
As shown in Figure 1, the described high-temperature wearable air cylinder structure of the embodiment of the invention comprises cylinder 1 and piston 2; Inwall at said cylinder is equipped with a gas inner cylinder sleeve 3, adopts interference fit between said gas inner cylinder sleeve 3 and the cylinder inner wall, is in more than 300 ℃ in the high temperature at cylinder 1; The gas inner cylinder sleeve 3 that will be in the normal temperature state is packed in the cylinder 1, and the thickness of said gas inner cylinder sleeve 3 is 3-5mm, and said gas inner cylinder sleeve 3 adopts high-temperature and wear-proofs to process; The internal surface of gas inner cylinder sleeve 3 is through smooth treatment; The outer surface of gas inner cylinder sleeve 3 and said cylinder inner wall all adopt friction treatment, and after guaranteeing that the gas inner cylinder sleeve is installed in cylinder interior, gas inner cylinder sleeve 3 can slippage from cylinder; Said piston 2 is installed in the said gas inner cylinder sleeve 3, and the pairing cylinder inner wall of the top dead center of piston 2 and lower dead center all has gas inner cylinder sleeve 3 in the zone.
The invention has the beneficial effects as follows; The creationary cylinder wear-resisting problem under the high temperature condition that solved; The gas inner cylinder sleeve of processing through the high-temperature and wear-proof of between cylinder and piston, packing into; The cost of cylinder in casting and high-temperature wearable processing procedure can be reduced greatly, cylinder wear-resisting performance under high temperature condition can be improved.
