Background technology
Chinese patent CN2303822Y discloses a kind of novel roller guide assembly (June 4 1997 applying date), it comprises support, bearing and rack-mount roller, water bumper is arranged between support and the bearing, water bumper is made of inside and outside cylinder barrel, piston, piston rod, spring, seal ring etc., and piston and spring are set in the plunger shaft.It mainly is thereby that so its buffer action is very limited, service life is also shorter by the length of spring compressed in the inner chamber and the realization buffer action that resets.
Summary of the invention
The utility model provides a kind of roller guide assembly of scalable hydraulic cushion power, and its installation, maintenance is convenient, long service life.
The utility model is achieved in that a kind of roller guide assembly, mainly comprise base, support and rack-mount roller, water bumper is arranged between support and the base, the cylinder barrel that water bumper mainly is made of inside and outside cylinder, piston, piston rod and end cap are formed, form outer oil cavity between outer shell and inner casing, the piston, oil pocket in forming between inner casing and the piston, be provided with spring in the outer oil cavity, spring is spacing by annulus on the piston, be provided with the interior oil circuit of steel ball and connection outer oil cavity and interior oil pocket in the piston, steel ball is positioned at an end of oil circuit; The cylinder barrel bottom is provided with outer oil circuit and is communicated with outer oil cavity and interior oil pocket, and outer oil circuit is provided with the flow regulating valve that has control apparatus.
The roller shaft of described roller by and cap be installed in the roller axis hole of support, and cap is in the seam of roller shaft outer end of hole, the other end of roller shaft is equipped with trapezoidal bearing, trapezoidal bearing outside has columnar flange, roller housing is contained in outside the flange, and the flange of a roller and an end face, the end cap of other end are solidly fixed; Be provided with identical seam outside the roller axis hole two ends on the described support; Described piston rod is a stainless steel; Described roller is the polyurethane wheel.
The utility model roller guide assembly has adopted water bumper, can regulate compensator or trimmer pressure as required, and cushion characteristic is good, strong shock resistance.Roller housing is contained on the flange, the flange of a roller and an end face, and the end cap of other end is fixed together, therefore when rolling wheel wear after,, roller and flange, end cap are unclamped as long as unclamp also cap between roller shaft and the support, just can change roller easily, installation and maintenance are convenient.The outer two ends of roller axis hole on the support are equipped with identical seam, and roller can be installed on arbitrary limit of support, to satisfy user's demand.Piston rod adopts stainless steel to prevent to get rusty, and roller is the polyurethane wheel, can prolong the service life of roller guide assembly greatly.
