Description
Technical Field
[0001] The utility model relates to a limiting device for the end face seal cover of a suspended speed reducer, belonging to the technical field of metallurgical industry mechanical equipment. Background Technique
[0002] A large number of weighing belt conveyors are arranged in the raw material receiving and unloading system of an iron and steel integrated enterprise. A weighing belt conveyor generally includes a driving drum, a suspended speed reducer, a conveyor belt, a frame, etc. One structural form of the suspended speed reducer is that the low-speed end of the speed reducer is a hollow shaft, and the hollow shaft is directly sleeved on the input shaft of the driving drum, and the two are connected by a key. On the other side of the outer shell of the low-speed shaft end of the speed reducer, a support plate is arranged. The support plate and the speed reducer shell are connected into one body by a plurality of bolts. The bottom end of the support plate and the base are hinged by a pin shaft, and the base is fixed to the support frame. Although this speed reducer is sleeved on the driving drum and the side support plate is arranged on the side for stability, at the four corners of the bottom panel of the speed reducer shell, a recessed threaded hole is reserved in the original design, that is, in addition to fixing the speed reducer by the hanging plus side support method, the speed reducer can also be fixed through the threaded holes reserved on the bottom plate of the speed reducer, and it can be selected according to actual needs.
[0003] In actual use, since the inside of the speed reducer is a worm and worm gear structure, and one side bearing of the worm is assembled in a fixed concave hole, and the other side bearing is assembled in a through hole of the shell. The outer ring of the bearing is successively an adjusting pad, an inner circlip, and a seal cover from the outside. And for some speed reducers, the service time has exceeded 15 years, and the inner circlip is gradually corroded and worn out of effectiveness, resulting in the end face seal cover running out, the lubricating oil flowing out, and the meshing tooth surface of the worm and worm gear of the speed reducer being damaged. Content of the Utility Model
[0004] The purpose of the utility model is to provide a limiting device for the end face seal cover of a suspended speed reducer, which prevents the seal cover from running out, ensures the normal lubrication of the speed reducer, and solves the problems existing in the background technique.
[0005] The technical solution of the utility model is as follows:
[0006] A limiting device for the end face seal cover of a suspended speed reducer includes an inner circlip, an adjusting pad, a fastening bolt, a tapered roller bearing, a worm, a worm gear, a seal cover, a suspended speed reducer housing, a side support plate, a pin shaft, a base and a support frame. The suspended speed reducer housing is fixed on the side support plate, the side support plate is hinged to the base by a pin shaft, and the base is fixed on the support frame; the inside of the suspended speed reducer is a worm and worm gear structure, and both ends of the worm are respectively rotatably connected to the suspended speed reducer housing through tapered roller bearings. Among them, the tapered roller bearing at one end of the worm is provided with an adjusting pad, an inner circlip and a seal cover, and a setscrew matched with the seal cover is arranged outside the seal cover, and the setscrew is threadedly connected to the limiting plate.
[0007] The limiting plate is L-shaped.
[0008] The top screw is threadedly connected to an edge of the L-shaped limiting plate, and the edge is arranged parallel to the sealing cover.
[0009] The other side of the L-shaped limiting plate is fixed to the bottom of the hanging reducer housing by bolts.
[0010] The utility model has the beneficial effect that the outer center of the sealing cover is supported by the top screw, thereby preventing the sealing cover from running outward and ensuring the normal lubrication of the reducer. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a schematic diagram of the structure of the utility model;
[0012] Figure 2 for Figure 1 Schematic diagram from left side;
[0013] Figure 3 for Figure 1 A partial enlarged schematic diagram;
[0014] In the figure: top screw 1, limit plate 2, inner retaining spring 3, adjustment pad 4, fastening bolt 5, tapered roller bearing 6, worm 7, worm wheel 8, sealing cover 9, suspended reducer housing 10, transmission drum input shaft 11, side support plate 12, pin 13, base 14, support frame 15, transmission drum 16. DETAILED DESCRIPTION
[0015] The present invention will be further described below by way of examples with reference to the accompanying drawings.
[0016] See attached Figures 1-3 A suspension reducer end face sealing cover limiting device comprises an inner retaining spring 3, an adjusting pad 4, a fastening bolt 5, a tapered roller bearing 6, a worm 7, a worm wheel 8, a sealing cover 9, a suspension reducer housing 10, a side support plate 12, a pin 13, a base 14 and a support frame 15, wherein the suspension reducer housing 10 is fixed on the side support plate 12, the side support plate 12 is hinged on the base 14 through the pin 13, and the base 14 is fixed on the support frame 15; the interior of the suspension reducer is a worm gear structure, and the two ends of the worm 7 are rotatably connected to the suspension reducer housing 10 through tapered roller bearings 6 respectively, wherein the tapered roller bearing 6 at one end of the worm 7 is provided with an adjusting pad 4, an inner retaining spring 3 and a sealing cover 9, and the outside of the sealing cover 9 is provided with a top screw 1 that matches the sealing cover 9, and the top screw 1 is threadedly connected to the limiting plate 2.
[0017] In this embodiment, refer to the attached Figures 1-3, the limiting plate 2 is an angle iron. One side of the angle iron is fixed to the lower part of the housing 10 of the suspended speed reducer by two fastening bolts 5. A threaded through hole is provided at the center of the other side of the angle iron. The threaded through hole cooperates with the setscrew 1. The end of the setscrew 1 contacts the center of the end face seal cover 9 of the worm. A certain pre-tightening force is applied to the setscrew 1, and the outside center of the seal cover 9 is held by the setscrew 1, thereby preventing the seal cover from moving outwards and ensuring the normal lubrication of the speed reducer.
