Embodiment
The mounting type of roller is provided with linear rail and roller slide block two large divisions in a kind of pair of raceway rolling wheel guide rails pair, and as shown in Figures 2 and 3, wherein the linear rail part is combined by guide rail matrix (1) and two raceway bodies (2) of being embedded in its both sides; Like Fig. 4, Fig. 5 and shown in Figure 7; The roller Slipper is by slide body (3) and roll wheel assembly (4) mounted thereto, clearance adjusting screw (5), to oval pin (6) and the roller lower cover (7) of roller shaft location, and end cap (8) and dust guard (9) composition.Like Fig. 8 and shown in Figure 9, the cross section of slide body (3) is a type, and its inner chamber is to meet vertical groove (B1) of linear rail section feature and a plurality of roll wheel assembly (4) height and enough wide grooves (B2) of meeting that both sides connect with it.Slide body (3) both sides be respectively equipped with groove (B2) with corresponding cylinder blind hole (B3), cylindrical hole (B4) and 1 longitudinal hole (B5) of quantity and position; One of them side is provided with the tapped hole (B6) that intersects vertically with cylinder blind hole (B3); Each cylinder blind hole (B3) is coaxial with corresponding cylindrical hole (B4); Each tapped hole (B6) intersects vertically with corresponding cylinder blind hole (B3), the cylinder blind hole (B3) of longitudinal hole (B5) and the homonymy part (A1) that connects.
Shown in figure 10, roll wheel assembly (4) can be made following three kinds of forms: overlap the double-row radial ball bearing form in the nothing of roller shaft (10) and interior cover (101) one, have interior cover double-row radial ball bearing form and biserial to add the form of single direction thrust ball bearing to bulbus cordis.Cover double-row radial ball bearing form and biserial are one section isometrical cylindrical body to the roller shaft (10) that bulbus cordis adds the single direction thrust ball bearing form in being used to have; Like Figure 11 a, the one of which end is provided with the circular groove (B8) of part (A1) shape that connects that meets longitudinal hole (B5) and cylinder blind hole (B3).Like Figure 11 b, the roller shaft that is used to not have interior cover form roller is that interior cover and roller shaft are made of one, and forms step surface (B7).There is an end of circular groove (B8) to insert cylinder blind hole (B3) roller shaft (10) of roll wheel assembly (4); As shown in Figure 5; Use roller lower cover (7) to cooperate with roller shaft (10) and cylindrical hole (B4) roll wheel assembly (4) is pressed in the groove (B2), step surface of roller shaft (B7) or single direction thrust ball bearing upper-end surface closely contact with roller lower cover (7) upper-end surface with slide body (3) grooves on two sides (B2) upper side.Utilize the drive fit of roller lower cover (7) and cylindrical hole (B4), roll wheel assembly (4) is fixing.For preventing the loosening or shift in position of roller lower cover (7), can junction of the edges of two sheets of paper screw (12) be set at itself and cylindrical hole (B4) junction plane place, as shown in Figure 6.
As shown in Figure 7; Because slide body (3) has the aperture of cylinder blind hole (B3 ') of tapped hole (B6) side bigger; With roller shaft (10) certain interval (C1) is arranged; Through using the oval pin (6) of different-diameter, adjustment screw (5) is adjusted and can be carried out the position adjustment by pair roller axle (4), thereby reach the adjustment of pair roller working clearance.
The invention provides the roll wheel assembly of various ways; The Gothicism annular groove (B9) of the overcoat of various rollers (11) outer cylinder surface has 2 characteristics that contact with raceway body (2); The load-up condition that can adapt to various directions and size, and the roller assembling mode that uses is also very simple.So the present invention has, and applicability is strong, lower-price characteristic, and considerable cost performance will be started out huge market.
