Technical field
The utility model relates to a kind of worm gear reducer device, particularly relates to a kind of super large moment worm gear reducer device.
Background technique
Valve actuator is the drive unit of valve opening or closedown, is the requisite important component part of valve.The performance quality of valve actuator directly affects, and even determines the sealability of valve, adjusting function, Safety performance and working life.
Along with carrying out of the Important Project such as the national south water to north, Northwest Liaoning water supply.The valve of super large-scale is constantly applied, and the moment of torsion of valve is constantly widened from tens original Wan Niu meter to a hundred or so Wan Niu meter.In current whole valve industry, high-torque valve speed reducer moment of torsion is generally 600000Nm, the development of restriction large bore valves industry.
Model utility content
The purpose of this utility model is just to provide a kind of super large moment worm gear reducer device to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises worm gear case lid, indicator panel, worm gear, worm gear case, rear end cover, adjusting nut, rear interstage sleeve, worm screw, front interstage sleeve, secondary straight-tooth case, third-level planetary case and the two aobvious case of planet, described Worm gear case is set on described indicator panel, its arranged outside has described Worm gear case lid, described worm gear is installed in described Worm gear case, described worm screw is fixed on described worm gear case by rear interstage sleeve and described front interstage sleeve, described adjusting nut is installed on one end of described worm screw, and be installed in described rear interstage sleeve, one end of described worm screw is provided with rear end cover, one end that described worm screw is positioned at described front interstage sleeve is provided with described secondary straight-tooth case, the outer end of described secondary gearbox is provided with described third-level planetary case, the two aobvious case of described planet is mutually meshing with the gear of described third-level planetary case and described secondary straight-tooth case respectively.
Further, the matching gap between described worm screw and described worm gear is regulated by described adjusting nut.
Further, described indicator panel and described worm gear case are fixed by caging bolt, and the arranged outside limited location bolt cover of described caging bolt.
The beneficial effects of the utility model are:
The utility model has the advantage of and by forward and backward interstage sleeve, worm screw axial force is applied on worm gear case, enable valve speed reducer bear 1200000Nm super large moment.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of a kind of super large moment worm gear reducer device described in the utility model.
Fig. 2 is the right TV structure schematic diagram of a kind of super large moment worm gear reducer device described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2: the utility model comprises worm gear case lid 1, indicator panel 2, worm gear 3, worm gear case 4, rear end cover 5, adjusting nut 6, rear interstage sleeve 7, worm screw 8, front interstage sleeve 9, secondary straight-tooth case 10, third-level planetary case 11 and the two aobvious case 12 of planet, Worm gear case 4 is set on indicator panel 2, its arranged outside has worm gear case lid 1, worm gear 3 is installed in Worm gear case 4, worm screw 8 is fixed on worm gear case 4 by rear interstage sleeve 7 and front interstage sleeve 9, adjusting nut 6 is installed on one end of worm screw 8, and be installed in rear interstage sleeve 7, one end of worm screw 8 is provided with rear end cover 5, one end that worm screw 8 is positioned at front interstage sleeve 9 is provided with secondary straight-tooth case 10, the outer end of secondary gearbox 10 is provided with third-level planetary case 11, the two aobvious case 12 of planet is mutually meshing with the gear of third-level planetary case 11 and secondary straight-tooth case 10 respectively, matching gap between worm screw 8 and worm gear 3 is regulated by adjusting nut 6, and indicator panel 2 is fixed by caging bolt 13 with worm gear case 4, and the arranged outside limited location bolt cover 14 of caging bolt 13.
Working principle of the present utility model is as follows:
The material selection QT500-7 of worm gear 3; Material selection 45 steel of worm screw 8; Material selection 45 steel of rear interstage sleeve 7 and front interstage sleeve 9, annealing in process before fine finishing.Front interstage sleeve 7 and rear interstage sleeve 9 design strength can bear the axial force under worm screw nominal moment of torsion 1.2 times of load.
The utility model structure is simple, reliable performance, utilizes nut to regulate matching gap between worm and worm wheel, utilizes interstage sleeve that the axial force tensile stress of worm screw is converted into pressure stress and be applied on worm gear case, substantially increase the bearing capacity of Worm gear case.
Those skilled in the art do not depart from essence of the present utility model and spirit, various deformation scheme can be had to realize the utility model, the foregoing is only the better feasible embodiment of the utility model, not thereby interest field of the present utility model is limited to, the equivalent structure change that all utilization the utility model specifications and accompanying drawing content are done, is all contained within interest field of the present utility model.
