The rolling ridge groove (42) corresponding to the rolling yoke (42) corresponding to the direction yoke retainer (4 〇) is provided with a rolling phase groove (52), and the smooth convex portion (5) is compliant. It should extend in the direction of the rolling element groove (10) of the load side retainer (10), and the smooth convex portion (51) abuts against the outer side of the end cover (10), and is held by the top surface (5) n of the smooth convex portion (8). Corresponding to the splicing surface (10) of the broken (10) against the end), so that the top surface (9) is kept stable against the top lap (10)), which will make the _ operation more stable; With the stability of the top surface (51Ό and the joint surface (10)), it is stable against the Kosi ^ extension: the effect of stability. 1259876 The same invention does not require a large change of the 5 hai negative side retainer (50), the structure of its smooth convex (5)) 丨 丨 今 , ,, and the use of plastic injection manufacturing, The product size variation is small; therefore, the present invention is effective for every μ, such as the linear linear slide movement, and the effect of the linear slide. (4) The reliance 70 keeps the fitting member easy to manufacture. It is worth noting that the joint between the directional turn retainer _ outwardly tapered guide portion (41) and the rolling side (10) groove (10) of the load side retainer (10) is The gap is derived from the size factor of the Na accessories. The main reason is as follows: 1. Because the linear guide is _ temperature range (the temperature is from -20〇C to 1ΠΠΥ", so the size due to temperature changes Variation, must be reserved for clearance to absorb. 2, two accessories in women's clothing must be in accordance with the dimensional tolerances to reserve clearance, to avoid the accessories are not easy to install. This month's X under the meter to get the clearance of spare parts , and ', hold-smooth convex. D (Dl) extended into the end cover length design value: parameter setting (please - and refer to the thirteenth figure): 1259876 ^ reserved gap B extended length C due to temperature caused by the size variation D Space reserved for tolerance L Retainer length 回流 Reflow top to bottom long Applicable temperature range Thermal expansion coefficient P Tolerance value reserved clearance" is the sum of the dimensional variation c due to temperature and the clearance D reserved for tolerance: C = Lx wx At Ό = 2p = + = A/ + . The smooth length (51) extension length B must be greater than the reserved clearance 乂 to effectively avoid gap generation: B >A = LxwxAt + 2p and consider the feasibility of implementation Sexuality, the extension length B is less than the reflux top to the bottom distance 13 Ϊ 259876. plus the reserved gap: ^<A + M So the optimal extension length of the smooth convex part (51) is: J + Af > B j ZX h, x △, + 2 households. In summary, the present invention maintains an outwardly projecting convex portion corresponding to the direction-rotating portion at the two ends of the load-side retainer, and the smooth convex portion conforms to the load side retainer. The direction of the groove of the rolling element extends, and the smooth convex portion abuts against the breaking portion of the end cap and maintains the outer side of the rolling element groove opening of the corresponding direction rotating portion holder (outside of the guiding portion); In addition to effectively improving the stability of the linear slide motion, the rolling element smoothness of the linear sliding can be effectively improved; therefore, the utility of the present invention is undoubted, and the unit connection disclosed in the embodiment of the present invention is applied for. I have not seen any publications before and have not used them publicly. Therefore, the "novelty" and "progressiveness" of the present invention have all been met, and the invention of the invention is proposed in accordance with the law, and the patent is granted as soon as possible.
