Please refer again to shown in Figure 2ly, slide 12 also can comprise four reflux assemblies 128, and each reflux assembly 128 correspondence is placed in backflow duct 125 and exteenal reflux passage.Particularly; Each reflux assembly 128 also can have an extension part U; When reflux assembly 128 correspondences are placed in backflow duct 125 and exteenal reflux passage; Extension part U correspondence is placed in the backflow duct 125, and the friction so that further minimizing ball 13 takes place when getting into backflow duct 125 through front cover 122a, rear end cover 122b makes ball 13 cross front cover 122a, rear end cover 122b in smooth-going earthing.
In addition; Each reflux assembly 128 also can have one the 3rd positioning part P3 respectively; And the two ends of exteenal reflux passage have the one four positioning part P4 corresponding with two the 3rd positioning part P3 of two relative reflux assemblies 128 respectively; And when reflux assembly 128 correspondences were placed in backflow duct 125 and exteenal reflux passage, the 3rd positioning part P3 can be sticked in the 4th positioning part P4.So, more be prone to the location in the time of can making reflux assembly 128 assemblings, also can increase the convenience of assembling.
In addition, a plurality of balls 13 are placed in said exteenal reflux passage and said backflow duct 125, and in the ball-recirculation approach that straight line transmission module 1 each assembly is formed progressive rolling movement, drive slide 12 and move relative to linear track body 11.
Please be simultaneously with reference to Fig. 2 and shown in Figure 5, wherein, Fig. 5 is the elevational schematic view of the slide 12 of Fig. 4.In addition, Fig. 5 does not show dust preventing component 123.
In the present embodiment, recirculation assembly 127 has two circulation piece 127a, 127b, and each circulation piece 127a, 127b have one of them part of ball channel P respectively.Whereby, can lower the processed complex degree of recirculation assembly 127, and cut down finished cost.In addition, the tangent direction that ball 16 can follow annular distance H1 gets into ball channel P, perhaps can get into circulation port H1 along the tangent direction of ball channel P, so, can make ball 16 when refluxing, pass through slide body 121 and recirculation assembly 127 more swimmingly.
Please with reference to shown in Fig. 6 A and Fig. 6 B, it is respectively the decomposing schematic representation of recirculation assembly 127.In this; Recirculation assembly 127 is except that being divided into two circulation piece 127a, 127b; Each circulation piece 127a, 127b also can have two circulation block V respectively; Said circulation block V links and forms ball channel P, can more lower the processed complex degree of recirculation assembly 127 whereby, and further cut down finished cost.
In addition, please refer again to shown in Figure 2ly, slide 12 also can comprise one group of front cover dust guard DP
1And one group of rear end cover dust guard DP
2, it is arranged at the opposite side of forward and backward end cap 122a, 122b opposing end surface E1, E2 respectively, and its function also is that to be used to prevent that foreign matter from invading slide 12 by the front end of slide 12 or rear end inner and cause the fault of straight line transmission module 1.
Please refer again to Fig. 1 and shown in Figure 3, screw rod 14 has a screw rod back flash 141, and the inboard of slide body 121 has an interior back flash 126 of corresponding screw rod back flash 141, and screw rod back flash 141 forms return flow line in interior back flash 126.In addition, ball 16 is placed in interior return flow line.When transmission device 15 drives screw rods 14 and rotates, roll in circulating path through a plurality of balls 16, can make screw rod 14 and slide 12 carry out relative spiral motion, and it is mobile to make slide 12 carry out linearity along screw rod 14.
In addition, please refer again to shown in Figure 2ly, slide 12 also can have an oiling cap 129 and an oil hole H2, and oiling cap 129 is embedded in oil hole H2.In this, the oil hole H2 that two oiling caps 129 are embedded in front cover 122a and rear end cover 122b respectively is an example.Wherein, manual or automatic (profit certainly) mode of can passing through is passed through lubricant oil (fat) in the oil hole H2 injection slide 12, and is to lubricate the exteenal reflux passages of 111 common formations of exteenal reflux groove 124 and rail slot, more smooth-going when screw rod 14 drive slides 12 are moved.
In sum, in the straight line transmission module according to the utility model since the linear track body in about the inboard single track groove is set respectively; Therefore, when grinding said rail slot, abrasive machining equipment can not need be changed less emery wheel; And grind the inboard of can be directly emery wheel being stretched into the linear track body, preferablely makes emery wheel and horizontal plane keep an angle and tilt to stretch into linear track body inboard and grind, so; Grinding work is easier to relatively; And grinding process does not need more exchange device, therefore, has effect of saving time and labor.In addition, the dust preventing component of the utility model straight line transmission module is arranged at the both sides of slide body and end cap respectively, and part is positioned on the linear track body at least.Whereby, after dust preventing component is installed, can fit and be covered on the linear track body; Therefore, remove and to prevent that foreign matter or liquid from invading the exteenal reflux passage between slide and the linear track body, produce noise when avoiding the start of straight line transmission module, pause, lose stable or cause outside the assembly damage; Adjustment after also being easy to assemble; The convenient applying that sees through external force reinforcement dust preventing component and linear track body is prevented because of the slit of error or other factors generation, further promotes protection effect.
