Abstract
The utility model relates to an oil seal of hydraulic power steering gear which is convenient to disassemble belonging to the hydraulic power steering gear accessory technical field. The oil seal is composed of an oil seal and a gasket deposited at bottom of the oil seal. The gasket is separated 3mm from housing. The gasket is 3mm in thickness. When the oil seal of steering gear malfunctions and it is necessary to disassemble and change, the oil seal can be easily disassembled by knocking the gasket and the oil seal can be taken out 100%, which greatly reduces changing difficulty of the oil seal and repairing cost of the steering gear. The problem that it is difficult to dissemble the prior steering gear once the steering gear malfunctions; it is difficult to clean the old oil seal completely most of the time and oil leakage exists after mounting a new one; it is necessary to dissemble and change the oil seal; and it is only to scrap the steering gear sometimes.
Description
Technical field:
The utility model relates to a kind of easy-to-dismount hydraulic power steering gear oil sealing, belongs to hydraulic power steering gear accessory technical field.
Technical background:
The deflector oil sealing is the hydraulic power steering gear packing element, and oil seal lip is held tightly on Spool assembly by oil seal spring, seals.Deflector in use owing to frequent the relatively rotating and relatively moving of each hard ware, can produce the metal worn particle of some, and these metal worn particles are brought into the oil seal lip place by hydraulic oil, can accelerate the wearing and tearing of oil sealing and Spool assembly.And the material at oil sealing sealing position is a Rubber Parts, and resistance to abrasion is relatively poor, so oil sealing generally uses 2-3 to cause seal failure because of severe wear, thereby produces the deflector leakage of oil.
At present domestic and international hydraulic power steering gear adopts the deflector of the valve integrated formula of shell more, this deflector manufacturing cost is relatively low, oil sealing on the gear wheel shaft of its Spool assembly is to be pressed into the housing middle part by certain pressure, because the oil sealed mechanical strength is lower, for guaranteeing not produce gross distortion behind the oil sealing pressurized, only leave the monolateral gap of 0.2-0.3mm between housing inner bore of step and the Spool assembly, in case oil seal failure like this, remove very difficulty, can't remove fully totally because of old oil sealing in the time of most of, back or leakage of oil are gone up in the fresh oil encapsulation, have to pull down the replacing oil sealing again.Sometimes even whole deflector have to be scrapped.
Summary of the invention:
The purpose of this utility model is: provide a kind of in the valve integrated formula deflector of shell housing and oil sealing between the structure of packing ring is set, oil sealing is in case the back convenient disassembly that lost efficacy, maintenance difficulty is little, oil sealing all can be taken out, make deflector repair rate height, the easy-to-dismount hydraulic power steering gear oil sealing that maintenance cost is low.
The utility model is to realize above-mentioned purpose by the following technical solutions:
A kind of easy-to-dismount hydraulic power steering gear oil sealing, it is made of oil sealing and packing ring, it is characterized in that: packing ring places steering gear housing that the bearing hole bottom of Spool assembly is installed, and oil sealing is housed above the packing ring, packing ring and housing be the gap of 3mm at interval, and the thickness of packing ring is 3mm.
The utility model beneficial effect compared with prior art is:
The utility model is equipped with packing ring in the bearing hole of steering gear housing installation Spool assembly, the 3mm gap is arranged between packing ring and housing, after in a single day oil sealing lost efficacy, the oil sealing convenient disassembly is simple, require low to maintenance man technical ability, energy 100% oil sealing is all taken out makes and reduced maintenance cost by deflector repair rate height.
Description of drawings:
Fig. 1 is a kind of easy-to-dismount hydraulic power steering gear oil sealed structural representation;
Fig. 2 is a kind of easy-to-dismount hydraulic power steering gear oil sealed scheme of installation.
Among the figure: 1, steering gear housing, 2, Spool assembly, 3, bearing, 4, oil sealing, 5, packing ring.
The specific embodiment:
This easy-to-dismount hydraulic power steering gear oil sealing is made of oil sealing 4 and packing ring 5, packing ring 4 is placed on the bearing hole bottom of the installation Spool assembly 2 of steering gear housing 1, packing ring 5 be contained in oil sealing 4 below, the diameter of packing ring 5 is than the little 3mm of bearing hole diameter of steering gear housing 1, the thickness of packing ring is 3mm, adopts the steel plate punching press to make (referring to accompanying drawing 1-2).
This easy-to-dismount hydraulic power steering gear oil sealing is that increase by one thickness is the packing ring 5 of 3mm between steering gear housing 1 and oil sealing 4, simultaneously, the hole that oil sealing 4 is installed in the steering gear housing 1 is enlarged 3mm, make the gap of leaving between packing ring 5 and the steering gear housing 1 about monolateral 1.5mm, like this, in case oil sealing 4 lost efficacy when needing dismounting and change, just can at an easy rate oil sealing 4 be pulled down by knocking packing ring 5.Greatly reduce the replacing difficulty of oil sealing 4, reduced the reparation difficulty and the rehabilitation cost of deflector.
