Abstract
The utility model discloses a telescoping hydraulic cylinder with an improved structure. The telescoping hydraulic cylinder with an improved structure is characterized in that a non-metal guide sleeve is arranged at the guiding inner wall of the whole sleeve. The telescoping hydraulic cylinder with an improved structure is provided with the non-metal guide sleeve at the whole guiding inner wall. The telescoping hydraulic cylinder with an improved structure adopts non-metal guiding material, the coefficient of friction of the guiding material is small, the abrasion resistance is good, and the sprain phenomenon of a cylinder can not happen because the excircle of the cylinder is not directly contacted with an inner bore. The utility model has long guiding distance, good guiding performance, small force of friction and no contact between the excircle of the cylinder and metal, and the scuffing of cylinder bore can not happen. The inner bore and the excircle have no steps, therefore, the material utilization is raised, and the material is economized by about 30%.
Description
Technical field
The utility model relates to the sleeve telescopic hydraulic cylinder.
Background technique
The structure of existing sleeve hydraulic cylinder all is to process a groove at the cylinder barrel endoporus, fill guide material in the groove, its drawback is that cylinder barrel cylindrical and another cylinder barrel endoporus pass through the guidance tape guided bearing, and guiding has compressibility, the cylinder barrel cylindrical directly produces easily with another cylinder barrel endoporus and contacts, form sliding friction,, often produce the cylinder barrel surface and pull because material is close.Very easily producing cylinder barrel after during granule fixed-contamination thing enters and is slidingly matched in addition pulls.
Summary of the invention
In order to solve the shortcoming that existing sleeve telescopic hydraulic cylinder is pulled cylinder barrel easily, the utility model proposes the sleeve telescopic hydraulic cylinder that improves structure, comprise sleeve, it is characterized in that: the guiding inwall in entire sleeve is provided with the non-metal guide cover.Above-mentioned improved sleeve telescopic hydraulic cylinder is provided with the non-metal guide cover at whole guiding inwall, improved sleeve telescopic hydraulic cylinder adopts the non-metal guide material, and the guide material friction factor is little, and wear resistance is good, the cylinder barrel cylindrical does not directly contact with endoporus, can not produce the phenomenon that cylinder barrel is pulled; The guiding distance, steering capability is good, frictional force is little, the cylinder barrel cylindrical not with Metal Contact, can not produce scuffing of cylinder bore; Endoporus, cylindrical do not have step, have improved stock utilization, and material saves about 30%.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the guiding inwall in entire sleeve 4 is furnished with 1,3 non-metal guide rings 2 of dust ring, y-type seal ring 3 successively.3 non-metal guide rings 2 constitute guide sleeve.
Claims (1)
1, improve the sleeve telescopic hydraulic cylinder of structure, comprise sleeve, it is characterized in that: the guiding inwall in entire sleeve is provided with the non-metal guide cover.
