Embodiment
See also Fig. 1 to Fig. 3, the drive mechanism assembly 10 of linear actuators provided by the utility model, a motor 101 that links a linear actuators 100, and be subjected to this motor 101 transmissions, this drive mechanism assembly 10 includes: main members such as a housing 20, a screw rod 30, a worm gear 40, two bearing 50A, 50B, a locking part 60, a locating part 66 and a loam cake 70.
These housing 20 inside have a long straight passage 22; This housing 20 is not technical characterictic of the present utility model place, only for illustrating, is not as the restriction important document at this.
This screw rod 30 is arranged in this housing 20 and is arranged in this passage 22, and these screw rod 30 front ends are arranged to clip district 301, are a groove with present embodiment, but not as limit, and be provided with a screw 302 in the middle of this clip district 301.
These worm gear 40 inside are screwed together in this screw rod 30,401 in this external teeth district, worm gear 40 stage casing links with this motor 101 and is driven by it and rotates, hole peripheral then is provided with one first joint portion 42 in these worm gear 40 top sections, is an internal tooth district with present embodiment, but not as limit.。
This two bearing 50A, 50B are arranged in this passage 22 and are sheathed on the end of this worm gear 40 and lay respectively at this worm gear 40 two opposite sides, and respectively paste respectively to this worm gear 40 and this housing 20 this bearing 50A, 50B two opposite sides.
This locking part 60 has a spiro tooth part 62 and a head 64, and this spiro tooth part 62 is locked in the screw 302 of this screw rod 30, and coaxial with this screw rod 30.
This locating part 66, it is provided with the blocking part 41 that an external form is coincide in 301 positions, clip district of this screw rod 30 relatively, and its outer peripheral edges are provided with one second joint portion 661 in addition, are an external tooth district with present embodiment, just can be meshing with first joint portion 42 of this worm gear 40.
This loam cake 70, utilize a plurality of screws 80 to be locked in this housing 20 outer faces, in order to this locking part 60 of cover cap and this locating part 66, and this bearing of packing 50A outer rim, outside packing strength by this loam cake 70 will make between this housing 20, this screw rod 30, this worm gear 40 and this bearing 50A, 50B and significantly reduce assembly clearance, with the machine error of these screw rod 30 axial displacements of effective reduction.
During the utility model assembling, be set in this bearing 50B, this worm gear 40, this bearing 50A on this screw rod 30 in regular turn and be placed in the passage 22 of these these housing 20 inside, the wherein clip district 301 corresponding engagings of the blocking part 41 of this locating part 66 and this screw rod 30, then with these second joint portion, 661 corresponding clips in first joint portion 42 of this worm gear 40, at last this locking part 60 is placed into the perforation of this locating part 66 and with the screw 302 of this this screw rod 30 and screw togather, and finish the strong fix of above-mentioned two bearing 50A, 50B.
At last, again with this loam cake 70 with a plurality of screws 80 with after this housing 20 combines, above-mentioned each element is placed in this housing 20, each interelement will can not produce the gap of assembling this moment, significantly promote the precision of linear actuators.
Via said structure, when this worm gear 40 of these motor 101 transmissions rotates, these worm gear 40 1 sides can be subjected to this housing 20 and stop, opposite side can be subjected to this locking part 60 locks and pull, so this screw rod 30 can produce any gap and retardation error phenomenon is arranged in major axis is neither when advancing forward or retreating backward.With regard on the structure, this drive mechanism assembly 10 replaces existing with the fixing person of a latch the more with this locking part 60, and it can provide the disassembling of element, assembling and maintenance activity; Moreover it can not produce the fit-up gap with above-mentioned two bearing 50A, 50B strong fix, significantly promotes the precision of linear actuators.
To sum up institute is old, and the utility model disclosed composed component in previous embodiment only for illustrating, is not the scope that is used for limiting this case, the alternative or variation of other equivalence element, and the claim that also should be this case contains.
