Abstract
The utility model relates to an output positioning device of a heavy-duty gearbox. An output shaft of the gearbox is connected to an output flange downwards via a flat key, a positioning groove is arranged on the outer circle of the lower end of the output shaft, two semi-circular positioning rings are arranged in the positioning groove and combined into a total circle, at least two screws are screwed on the outer circle surface of each semi-circular positioning ring so that the semi-circular positioning ring is locked on the output shaft, nuts of the screws are provided with radial through holes, and adjacent screws are fixed and can not be loosened by means of penetrating locking parts into the radial through holes on the adjacent screws on the two semi-circular positioning rings. The two semi-circular positioning rings are mounted in the positioning groove on the output shaft below the flange and are locked on the output shaft by the screws, and the screws are locked by the locking parts, so that output positioning of the heavy-duty gearbox is realized. In addition, the output positioning device is compact in integral structure, the positioning rings are connected reliably and high in bearing capacity, the flange is stable and not easy to fall off so that falling-off of output flanges on heavy-duty occasions can be avoided, and the output positioning device is safe in use and long in service life accordingly.
Description
Technical field
The utility model relates to a kind of gear-box output positioning device, is that a kind of heavy-load gear box exports vertically downward, prevents that flange from moving the positioning device that comes off on output shaft specifically.
Background technique
Heavy-load gear box is mainly used in industries such as making copper pipe, cable, and the output flange institute carries product weight of heavy-load gear box often causes output flange and reel to come off at the 10-20 ton.In order to solve the flange problem that easily comes off, method commonly used at present has two kinds: the one, and adopt the swelling dish to be connected with screw, in use the screw fatigue of swelling dish makes tension force not enough, easily causes flange to come off; Another kind is to adopt the axle head baffle plate to be locked by screw, and in use the screw on the axle head baffle plate is easily progressively loosening, finally causes flange to come off.Said apparatus all fails effectively to lock the positioning device of flange, the locking and positioning weak effect.
Summary of the invention
In order to solve heavy-load gear box flange positioning and locking weak effect in the prior art, deficiencies such as flange easily comes off, and usage safety performance is low, the life-span is short, the utility model provides a kind of positioning and locking effective, the flange difficult drop-off, heavy-load gear box output positioning device safe in utilization, that the life-span is long.
The technical solution adopted in the utility model is: a kind of heavy-load gear box output positioning device, the output shaft of gear-box connects output flange downwards through flat key, output shaft lower end external diameter is provided with locating slot, it is characterized in that: be provided with two semicircle positioning rings in the described locating slot, two semicircle positioning rings are combined into full circle, all be screwed with at least two screws on the periphery of every semicircle positioning ring semicircle positioning ring is lock onto on the output shaft.
Further, described two screws are located at the two ends of semicircle positioning ring respectively.
Again further, the nut of described screw is provided with radial direction through hole, and the radial direction through hole cross-under locking element on two semicircle positioning rings on the adjacent screw is fixing locking with adjacent screw.
When heavy-load gear box is assembled, at first with flange through the downward output shaft of flat key connection gear case, by flange below two semicircle positioning rings are snapped fits in the locating slot on the output shaft external diameter of flange below, two semicircle positioning rings are corresponding forms full circle shapes; Again many screws are passed every semicircle positioning ring respectively semicircle positioning ring is locked on the output shaft, with locking element the radial direction through hole on the nut of adjacent screw on two semicircle positioning rings is twisted and connect firmly.
Adopt above technological scheme, the beneficial effect that the utility model reaches is: adopt two semicircle positioning rings to be placed in the locating slot, positioning ring assembling, convenient disassembly are convenient to safeguard; On output shaft, and adjacent screw is locked through locking element on two semicircle positioning rings through two above screw lock for two semicircle positioning rings, and it is firm that positioning ring connects, be difficult for loosening and displacement, the positioning ring bearing capacity is strong, and the flange difficult drop-off is fit to heavily loaded occasion and uses.
The utility model adopts two semicircle positioning rings to pack in the locating slot on the output shaft of flange below, and be locked on the output shaft positioning ring and the output location of screw lock being realized the heavy-load gear box flange with locking element with screw, compact overall structure, it is firm that positioning ring connects, bearing capacity is strong, flange is stablized difficult drop-off, can effectively prevent coming off of heavily loaded occasion output flange, and is safe in utilization, the life-span is long.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the semicircle locating ring structure schematic representation of the utility model.
Among the figure: flange 1, output shaft 2, flat key 3, locating slot 4, semicircle positioning ring 5,51, screw 6,61, radial direction through hole 7,71, locking element 8.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Shown in Fig. 1,2, heavy-load gear box output positioning device mainly comprises flange 1, output shaft 2 and two semicircle positioning rings 5,51.Flange 1 is through the output shaft 2 of flat key 3 connection gear casees, output shaft 2 external diameters of flange 1 below are provided with locating slot 4, be provided with two semicircle positioning rings 5,51 in the locating slot 4 to being connected into full circle, the screw 6,61 that two ends on every semicircle positioning ring periphery are screwed with band radial direction through hole 7,71 respectively lock onto semicircle positioning ring on the output shaft 2, and separately radial direction through hole 7, the 71 cross-under locking elements 8 of screw 6,61 are fixing locking with two screw lock on semicircle positioning ring 5,51 abutting ends.
When producing, two semicircle positioning rings 5,51 are packed in the locating slot 4, beat the interior corresponding screw hole of semicircle positioning ring 5,51 and output shaft 2 locating slots 4; In when assembling, flange 1 through the downward output shaft 2 of flat key 3 connection gear casees, is snapped fits into two semicircle positioning rings 5,51 in the locating slot 4 on flange 1 below output shaft 2 external diameters by flange 1 below, two semicircle positioning rings 5,51 are corresponding forms full circle shapes; Again many screws 6,61 are passed every semicircle positioning ring respectively semicircle positioning ring is locked on the output shaft 2, with locking element the radial direction through hole on the nut of adjacent screw on two semicircle positioning rings 7,71 is twisted and connect firmly.
