Abstract
The utility model relates to a kind of Worm gear case, and particularly relate to a kind of stable Worm gear case, this Worm gear case comprises casing, case lid; Worm gear is axially arranged with in described casing, the worm screw be provided with casing internal upper part is rotatably assorted, described worm gear center is provided with worm gear axis hole, it is characterized in that, described worm gear axis hole is circular, and be provided with ladder platform in worm gear axis hole central position, described ladder platform is inserted with the cylinder worm-wheel shaft coordinated with worm gear axis hole keyway.Because described worm gear axis hole is circular; and be provided with ladder platform in worm gear axis hole central position; described ladder platform is inserted with the cylinder worm-wheel shaft coordinated with worm gear axis hole keyway; when torsion exports excessive; the key be located in worm gear axis hole and worm-wheel shaft keyway is first destroyed; thus protect Worm gear case, prevent worm gear and worm screw from destroying because torsion is excessive, make it stable.
Description
Technical field
The utility model relates to a kind of Worm gear case, particularly relates to a kind of stable Worm gear case.
Background technique
At present, Worm gear case is applied widely in industrial production and engineering construction, plays very important effect.Existing a kind of stable Worm gear case, this Worm gear case comprises casing, case lid; Worm gear is axially arranged with in described casing, the worm screw be provided with casing internal upper part is rotatably assorted, described worm gear center is provided with worm gear axis hole, wherein worm gear axis hole is square hole, and worm-wheel shaft front end is also set to coordinate with square hole square, and when controlling torsion and being excessive, worm-wheel shaft drives the Power output of worm gear and worm screw, worm gear and worm screw are damaged, and Worm gear case runs and is destroyed.
Model utility content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, provides a kind of protection Worm gear case, prevent worm gear and worm screw from the stable Worm gear case destroyed occurring because torsion is excessive.
The utility model is achieved by the following technical programs:
A stable Worm gear case, this Worm gear case comprises casing, case lid; Worm gear is axially arranged with in described casing, the worm screw be provided with casing internal upper part is rotatably assorted, described worm gear center is provided with worm gear axis hole, it is characterized in that, described worm gear axis hole is circular, and be provided with ladder platform in worm gear axis hole central position, described ladder platform is inserted with the cylinder worm-wheel shaft coordinated with worm gear axis hole keyway.
The beneficial effects of the utility model are:
Because described worm gear axis hole is circular; and be provided with ladder platform in worm gear axis hole central position; described ladder platform is inserted with the cylinder worm-wheel shaft coordinated with worm gear axis hole keyway; when torsion exports excessive; the key be located in worm gear axis hole and worm-wheel shaft keyway is first destroyed; thus protect Worm gear case, prevent worm gear and worm screw from destroying because torsion is excessive, make it stable.
Accompanying drawing explanation
Fig. 1 is plan structure schematic diagram of the present utility model.
Fig. 2 is perspective view of the present utility model.
In figure: 1. casing, 2. worm gear, 3. worm screw, 4. keyway, 5. worm gear axis hole, 6. worm-wheel shaft, 7. case lid, 8. ladder platform.
Embodiment
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing and most preferred embodiment, the utility model is described in further detail.
As shown in Figure 1, this Worm gear case of the utility model comprises casing 1, case lid 7; Worm gear 2 is axially arranged with in described casing, the worm screw 3 be provided with casing internal upper part is rotatably assorted, described worm gear center is provided with worm gear axis hole 5, it is characterized in that, described worm gear axis hole is circular, and be provided with ladder platform 8 in worm gear axis hole central position, described ladder platform is inserted with the cylinder worm-wheel shaft 6 coordinated with worm gear axis hole keyway.This spacing worm-wheel shaft position of routine scala media halfpace, makes it move more steady.
Because described worm gear axis hole is circular; and be provided with ladder platform in worm gear axis hole central position; described ladder platform is inserted with the cylinder worm-wheel shaft coordinated with worm gear axis hole keyway; when torsion exports excessive; the key be located in worm gear axis hole keyway 4 and in worm-wheel shaft keyway is first destroyed; thus protect Worm gear case, prevent worm gear and worm screw from destroying because torsion is excessive, make it stable.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
