Some steel balls, each steel ball is installed in the guide channel of this inner sleeve respectively, makes each steel ball be unlikely each profile groove;
One overcoat, the end face of this overcoat is provided with one second positioning means, and this overcoat relative to each profile groove position inner edge surface respectively projection go out a bump, each bump has a pushing and pressing face respectively relative to each profile groove position, and this inner sleeve is installed in this overcoat, utilize this first positioning means and this second positioning means to assemble to locate, the pushing and pressing face of each bump of this overcoat is pushed against respectively steel ball that each is positioned at the profile groove of this inner sleeve;
One fastener, the installing of this fastener is positioned the nearly bottom surface desired location of this inner sleeve and this overcoat, this inner sleeve is unlikely and deviates from from this jacket internal.
Wherein, each profile groove of this inner sleeve is strip.
Wherein, this first positioning means is two projections be oppositely arranged, and this second positioning means is two breach be oppositely arranged, and this inner sleeve is installed in this overcoat, utilizes this two group of bumps to set and is positioned at this two breach.
Wherein, the guide channel ovalize closed shape of this inner sleeve.
Wherein, this fastener is that C type is buckled.
Wherein, each guide channel of this inner sleeve and each bump of this overcoat have according to center line is the tilt angle tilted between 3 degree ~ 8 degree.
Wherein, this tilt angle A is preferably 5 degree.
The utility model advantage and effect are: provide a kind of problem reducing negative pressure tolerance, reduce the vibration situation in transmission between assembly, promote and make dynamic stability, make the unqualified steel ball guide sleeve structure of transmission stroke.There is provided one to make efficiency of movement high, effectively increase the production capacity of mechanical actuation, avoid steel ball to come off, reduce the damage of mould, the steel ball guide sleeve structure effectively increased the service life.

[embodiment]
First, shown in Fig. 1-7, the utility model is a kind of steel ball guide sleeve structure, it comprises: an inner sleeve 10, this inner sleeve 10 is hollow cylinder, the end face of this inner sleeve 10 is provided with one first positioning means, and the outer periphery of this inner sleeve 10 are provided with the guide channel 11 of some elliptical closed shapes, and each guide channel 11 has the profile groove 12 of a permeable type respectively;
Dry steel ball 20, each steel ball 20 is installed in the guide channel 11 of this inner sleeve 10 respectively, makes each steel ball 20 be unlikely each profile groove 12;
One overcoat 30, this overcoat 30 is the cylindrical shell of hollow, the end face of this overcoat 30 is provided with one second positioning means, and this overcoat 30 relative to each profile groove 12 position inner edge surface respectively projection go out a bump 31, each bump 31 has a pushing and pressing face 32 respectively relative to each profile groove 12 position, and this inner sleeve 10 is installed in this overcoat 30, utilize this first positioning means and this second positioning means to assemble to locate, make the pushing and pressing face 32 of each bump 31 of this overcoat 30 be pushed against the steel ball 20 of the profile groove 12 that each is positioned at this inner sleeve 10 respectively;
One fastener 40, the installing of this fastener 40 is positioned this inner sleeve 10 and the nearly bottom surface desired location of this overcoat 30, this inner sleeve 10 is unlikely and deviates from from this overcoat 30 inside.
Wherein, each profile groove 12 of this inner sleeve 10 is strip.
Wherein, this first positioning means is two projections be oppositely arranged 13, and this second positioning means is two breach be oppositely arranged 33, and this inner sleeve 10 is installed in this overcoat 30, utilizes this two projection 13 to assemble and is positioned in this two breach 33.
