The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment, the present invention is further illustrated.
As shown in Fig. 1-4, the manual executive device of a kind of Direct Travel, it comprises casing 1, actuating unit and protection mechanism.
Described actuating unit comprises the worm screw 10 that is arranged in casing, with the worm screw worm gear 7 that is connected, described worm gear is positioned at casing and is socketed a leading screw 4, this worm gear is connected with casing 1 by tapered roller bearing 6, described protection mechanism also comprises end cap 11 and side cover 12, and described side cover is connected with casing 1 by end cap, passes worm screw 10 parts of casing 1, a part is covered with described side cover 12, and the front end of another part connects a handwheel 13.
Above-mentioned lid effective inner structure of protecting the manual executive device of this Direct Travel is set, in use can reduce the wearing and tearing of parts and unnecessary destruction, and the design of tapered roller bearing can well be played worm gear is supported and the effect of location.
Described protection mechanism comprises the case lid 2 coordinated with casing 1, and leading screw 4 is arranged in case lid 2, and its part cover that wears out case lid has leading screw cover 3, and leading screw cover 3 is fixed on case lid 2.Described leading screw has keyway along its axis direction, and the guide runner 5 affixed with case lid 2 by socket head cap screw 17 matches with keyway.
Effective cooperation of guide runner and keyway, can only be axial motion so that the motion of leading screw is limited, and steering capability is good like this, and resistance is little, can be applied in large-scale lead-screw drive mechanism.
Casing 1 with case lid 2 for being threaded, at case lid, 2 edges are provided with screw, are connected with a recessed end holding screw 14 in this screw, and casing 1 is provided with the unthreaded hole matched with the screw of case lid 2, this unthreaded hole is built-in with a steel ball 15, and recessed end place's interlock of described steel ball and recessed end holding screw 14.
Above-mentioned recessed end holding screw and the cooperation of steel ball, can in the device assembling, adjust as required predetermincd tension, make casing and case lid stressed evenly, sealing effectiveness strengthens, and this design can make the device convenient disassembly, can guarantee the conformability of position while reinstalling, also can prevent when device is placed work outside because of the device problem of case lid of not opening of getting rusty.
The present embodiment principle of work: during hand wheel rotating, can drive the rotation of worm and wormwheel, therefore be socketed on leading screw in worm gear and also can produce axial thrust due to the restriction of guide runner thereupon, with this, just can realize the running of the manual executive device of Direct Travel.
