Embodiment
Novel shaft transmission device of the present utility model is introduced in detail below in conjunction with Fig. 1, Fig. 2, Fig. 3, it comprises driving link 1 and driven member 2, this driving link is engaged by two groups of teeth 3 with driven member, when tooth described on driving link group is rectangular teeth, another on driven member is organized described tooth and is corresponded to V-arrangement tooth; When group tooth of on driving link is V-arrangement tooth, another group tooth on driven member corresponds to rectangular teeth, and the Surface of action of described V-arrangement tooth is helicoid 31, and the Surface of action of rectangular teeth is plane 32 in axial direction.Driving link is rotated and is moved axially by the Planar realization driving link of the axial direction of Surface of action or the outside of driven member, now the helicoid of driving link is in the helicoid of driven member the state be meshed all the time, namely the state that face contacts with face is in all the time, therefore, to operate steadily, reliably, and processing is comparatively simple, also can reduce component wear, the working life of member for prolonging.Driving link of the present utility model is connected with splined shaft 5 respectively by a spline housing 4 with driven member, its registration, ensures that driving link is concentric with driven member, can reduce the fault point.
In implementation process, described driving link and driven member are installed in an axle sleeve 6, and axle sleeve adopts hub splines, and this axle sleeve one end is provided with supporting base 7, the other end is provided with spring seat 8, one section, the described axle sleeve between supporting base and spring seat is alternately arranged with several inside and outside friction disk 9,10; Several support guide rod 11 one end is fastening through spring seat, several outside friction disc, supporting base and this supporting base successively, described several support guide rod the other end and spring pressure plate 12 fastening, the described support guide rod one section between spring pressure plate and spring seat, between spring seat and adjacent external friction dish, between two adjacent external friction dishes is all arranged with spring 13.After motor obtains electric startup, moment of torsion passes to driving link by splined shaft and makes it rotate, due to the effect of load inertia power, interaction force is produced between driven member and the Surface of action of driving link, and move axially relatively, and then by spring, spring seat being moved, inside and outside friction disk is thrown off, brake release; When relative movement is to the terminal of axial plane, moment of torsion passes to driven member by the plane of axis and helicoid, and moment of torsion is passed to splined shaft by driven member, and then can pass to speed reducer and complete moment of torsion transmission and brake release process.
When motor dead electricity, motor no longer includes moment of torsion and exports, and the interaction force between Surface of action disappears, spring pressure forces spring seat oppositely movement, and inside and outside friction disk is progressively fitted, along with further compression of the spring, braking force progressively strengthens, and its instant impact is little, finally reaches stable braking force.Now braking can divide two-part, and a part gives motor braking, and a part is braked to main frame, to the braking force of motor because engagement relation of plane counteracts partial spring power, therefore, after stopping, acting force of the spring all acts on friction plate, plays the effect of large braking force parking.
Further, be provided with several inner guide 14, described in each, inner guide one end is each passed through internal friction disc described in each, the inner guide the other end is provided with nut 15, this the other end and the internal friction disc near nut side, by screw threads for fastening, the described inner guide between adjacent two internal friction discs one section are provided with Compress Spring 16.Break can be made like this to open steadily.
Be provided with several pull bar 17, pull bar one end described in each successively through spring pressure plate, spring seat, and is threaded with spring seat, and each pull bar the other end is provided with handle 18, by the spring force between rotatable handle Regulation spring seat and spring pressure plate.After transmission device stops transmission, by rotatable handle, the distance between spring seat and spring pressure plate is diminished, spring-compressed; Along with further rotating handle, inside and outside friction disk moves vertically, causes inside and outside friction disk to be separated, and then brake off.
In implementation process, described supporting base is provided with several push rod 19, each push rod one end successively through end thereof contacts described in supporting base, several outside friction disc and pull bar, each push rod the other end and supporting base fastening.When rotatable handle, pull bar withstands by push rod, and spring seat is moved, and guarantees that inside and outside friction disk is separated; Further, on pull bar described in each root inside the spring pressure plate, radial direction is provided with pivot pin 20, is arranged with stage clip 21 between pivot pin and spring spring pressure plate, thus prevents pull bar from loosening, comes off.
In implementation process, external friction dish described in each is made up of two semi-rings.When disc wearing and tearing need change time, without the need to whole transmission device is taken apart, and only need take apart section components just can realize replacing; Described in each support guide rod, one end is tapered, can ensure to coordinate tight, stable drive.
Above-mentioned mode of execution is only for illustration of the utility model, and be not to restriction of the present utility model, the those of ordinary skill of relevant technical field, when not departing from the utility model spirit and scope, can also make various change and modification, therefore all equivalent technological schemes also should belong to category of the present utility model.
