Abstract
The utility model discloses a valve actuating gear including a case cover and a case body on which a worm slot is provided, and an axle hole communicating to the worm slot is provided on one side of the case body. One end of the worm bar in the worm slot is connected with the hand wheel through the axle hole, and a turbine engaged with the worm bar is provided on the lower part of the case. The shaft of the turbine is connected with the valve, and a repulsion pad positioned in the worm slot is sleeved on the worm bar while the external diameter of the repulsion pad is longer than the inner diameter of the axel hole.The utility modle has the advantages of simple structure, low cost and easy operation for dismounting or fixing.
Description
Technical field
The utility model relates to a kind of transmission device, exactly relates to a kind of valve bandle set that is applicable to oil, chemical industry and water supply and sewage industry.
Background technique
At present, the kind of drive that adopts worm screw to cooperate the worm gear drive valve to rotate is widely used in the industries such as oil, chemical industry and water supply and sewage.Worm screw and turbine are set in the casing.Before the assembling worm screw, need is one side closed worm hole with casing with boring machine or Cutter Body Processing with Machining Center earlier, the component location guide taper roller bearing is on worm screw and place in the worm hole, like this, the dimensional accuracy of worm hole and position accuracy demand are than higher, and worm hole is an elongated hole, need special boring machine or machining center just can finish, the tapered roller bearing market price is high, and therefore, cost of production is higher; For overcoming bearing axial displacement, the pad that needs to increase the spacing obturator of bearing and adjust bearing axial clearance, assembling and the loaded down with trivial details inconvenience of unloading process.
Summary of the invention
The utility model is intended to the deficiency at above-mentioned present situation, and a kind of valve bandle set of simple in structure, with low cost, easy accessibility is provided.
For achieving the above object, the utility model has adopted following technological scheme:
A kind of valve bandle set, comprise case lid and casing, described casing top is provided with the worm screw groove, the axis hole that is communicated with the worm screw groove is located at a side of casing, place worm screw one end in the worm screw groove to pass axis hole and be connected with handwheel, be arranged at lower box with the turbine of worm meshing transmission, the turbine shaft of described turbine is connected with valve, it is characterized in that: be socketed with the thrust disc that places in the worm screw groove on the described worm screw, the external diameter of described thrust disc is greater than the internal diameter of axis hole.
Described thrust disc is two, places the two ends of worm screw groove respectively.
Be provided with two needle bearings between described worm screw and turbine engagement position and two thrust discs.
Be provided with sealing gasket in the described axis hole, described sealing gasket is socketed on the worm screw.
Between casing and case lid, be provided with asbestos packing.
Advantage of the present utility model is:
1, the utility model adopts worm screw groove and axis hole is set on casing, the diameter of worm screw groove is bigger than axis hole, a worm screw that only needs to be socketed with sealing gasket, thrust disc and needle bearing in assembly process places worm screw groove and axis hole to get final product, and has simplified the installation step of conventional valves transmission device, simple in structure, convenient disassembly, transmission efficiency height.
2, the utility model adopts needle bearing to replace existing tapered roller bearing, has saved cost of production.
3, the utility model adopts worm screw groove and axis hole is set on casing, do not adopt the structure of traditional elongated hole, the elongated hole dimensional accuracy and the position accuracy demand height of conventional valves transmission device have been avoided, the technical problem that process equipment needs boring machine or machining center just can finish, the utility model adopts cylindrical bar milling cutter processing, and dimensional accuracy is easy to guarantee.

Embodiment
Embodiment 1
A kind of valve bandle set, comprise case lid 1 and casing 2, described casing 2 tops are provided with worm screw groove 3, the axis hole 4 that is communicated with worm screw groove 3 is located at a side of casing 2, place worm screw 5 one ends in the worm screw groove 3 to pass axis hole 4 and be connected with handwheel 6, be arranged at casing 2 bottoms with the turbine 7 of worm screw 5 engagement driving, the turbine shaft 8 of described turbine 7 is connected with valve 9, be socketed with the thrust disc 10 that places in the worm screw groove 3 on the described worm screw 5, the external diameter of described thrust disc 10 is greater than the internal diameter of axis hole 4.Described thrust disc 10 is two, places the two ends of worm screw groove 3 respectively.Be provided with two needle bearings 11 between described worm screw 5 and turbine 7 engagement positions and two thrust discs 10.Be provided with sealing gasket 12 in the described axis hole 4, described sealing gasket 12 is socketed on the worm screw.Between casing 2 and case lid 1, also establish asbestos packing 13.
Worm screw groove 3 on the casing 2 and axis hole 4 are milled rectangularity on milling machine, sealing gasket 12, thrust disc 10 and needle bearing 11 are socketed on the worm screw 5 by position shown in Figure 1.During assembling, the worm screw 5 that is socketed with sealing gasket 12, thrust disc 10 and needle bearing 11 is placed in worm screw groove 3 and the axis hole 4, the turbine shaft 8 of turbine 7 connects valve 9, asbestos packing 13 place mats are on casing 2, case lid 1 usefulness bolt or pin are fixedlyed connected with casing 2, worm screw 5 is connected with the hand wheel shaft of handwheel 6, and the utility model assembling finishes.The utility model does not adopt the structural design of traditional elongated hole, avoid the dimensional accuracy and the position accuracy demand height of elongated hole, the technical problem that process equipment needs boring machine or machining center just can finish, cost of production reduces greatly, do not need to increase the axial displacement that bearing axial limiting part fixes bearing yet, simple in structure, easy accessibility.
The utility model is not limited to the foregoing description; in the design scope that the utility model claim is limited; those skilled in the art also can do some conspicuous changes to the foregoing description, but these changes all should fall within the protection domain as the utility model claim.
