It is stifled that one exhaust is set on rack pinion chamber, exhaust is blocked up as conventional use of accessory, and a L is provided centrally with Exhaust is blocked up and is tightened, realize the sealing of rack pinion chamber when oscillating oil cylinder is stored or this is not used by the through-hole of shape, When use, by the stifled a few road screw threads of release of exhaust, rack pinion chamber and extraneous connection are realized, when the intracavitary temperature of rack pinion Degree increases and air pressure when increase, the position pressure release that air pressure can be stifled from exhaust, but extraneous moisture is by being vented in order to prevent It is stifled to enter in rack pinion chamber, rubber hose is installed in exhaust stifled end, extraneous moisture can nature in rubber hose Liquefaction congeal into water droplet and flowed out by rubber hose;Being vented stifled position simultaneously also has the function of detection, when in rack pinion chamber When into hydraulic oil, hydraulic oil can from exhaust it is stifled in outflow, convenient for discovery in time, on-call maintenance.In rack pinion chamber Lubricant grease is that viscosity is higher, and poor fluidity, the hydraulic oil only entered can flow out.
Based on the above technical solution, the utility model is to reach the stability of the convenience and equipment that use, Following improvement can also be made to above-mentioned technical solution:
Further, external seal ring recess, intermediate seal ring recess and inner seal ring slot are provided on the rubbing surface of the piston; One U-shaped circle of installation and one O-ring of installation in the groove of U-shaped circle in the external seal ring recess;In intermediate seal ring recess One regular rubber ring is installed and a lips side nylon slip ring is installed on the outside of regular rubber ring;Installation one in inner seal ring slot A support ring.The knockdown sealing of multiple tracks, can increase leakproofness.
Further, the exhaust is stifled is threadably secured installation cabinet between, be vented stifled front end use chamfering at Shape is provided in gas vent and the step that is vented stifled front end cooperation.
Further, the rack gear has two.
Further, the piston is installed together by connection bolt with rack gear.
Further, the material of the support watt is copper.
The utility model has the beneficial effects that rack-and-pinion chamber is closed when oscillating oil cylinder does not work, extraneous vapor is prevented Into;Rack-and-pinion chamber opens wide when oscillating oil cylinder works, while increasing rubber hose, is guaranteeing that it is same that rack-and-pinion chamber does not build the pressure When, effectively prevent vapor to enter, and then exclude rack-and-pinion cavity pressure increase and caused by security risk.
