Abstract
The invention discloses a gear case of worm and worm gear. The gear case comprises a box body of a symmetrically structure, two ends of the box body are respectively provided with a mounting port, and two ends of the inner wall of the box body are symmetrically provided with grooves; a worm is assembled into the box body through any one mounting port; a first conical angular contact bearing is sleeved at one end of the worm, a second conical angular contact bearing is sleeved at the other end of the worm, an opening gap circle is further sleeved on the outer periphery of the second conical angular contact bearing, is of a circular ring shape, and is provided with an opening, one lug boss or more lug bosses is/are arranged on the upper surface of the opening gap circle, and the number of the lug boss can set as actually required; the lug boss(es) is/are clamped into the grooves; and box covers are respectively assembled into the box body and fastened from the two mounting ports so as to match the worm to limit the first conical angular contact bearing, the second conical angular contact bearing and the opening gap circle. According to the invention, the purpose of assembling the gear case with two rotation directions by adopting the same box body is achieved.
Description
Technical field
The present invention relates to a kind of worm and gear gear-box.
Background technique
Usually the worm screw of worm and gear gear-box is an input end, and worm gear is an output terminal.General clockwise input, the gear-box of output is called the right-hand teeth roller box counterclockwise; Input clockwise, the gear-box of output is called the left-hand teeth roller box counterclockwise.
Present worm and gear gear-box, a secondary worm and gear and a casing can only be assembled into the left-hand teeth roller box together, maybe can only be assembled into the right-hand teeth roller box.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of existing technology, provide a kind of and can use the same worm and gear of same casing, as long as the direction of transposing worm screw assembling just can realize the left-handed or right-hand teeth roller box of assembling.
Technological scheme: in order to realize above purpose, a kind of worm and gear gear-box that the present invention proposes comprises the casing of symmetrical configuration being respectively equipped with mount inlet in this tank ends, is provided with groove symmetrically at the two ends of cabinet wall;
Worm screw is packed into from any mount inlet in the casing;
The first cone angle contact bearing is set in worm screw one end; The second cone angle contact bearing is set in the worm screw the other end; And at the also sheathed opened gap circle of this second cone angle contact bearing periphery, this opened gap circle is circular, and has opening; The surface is provided with boss above that, and boss quantity can be provided with one or more according to actual needs; Described boss snaps in groove;
Case lid is respectively charged into casing and fastening from two mount inlets, cooperates the worm screw reality first cone angle contact bearing, and it is spacing that the second cone angle contact bearing and opened gap are justified.
The internal diameter of the integral body that described second cone angle contact bearing and opened gap are round-formed and external diameter equate with the internal diameter and the external diameter of the first cone angle contact bearing.
Working principle: worm screw is packed into from casing one end in it, and the rotation of worm screw clockwise direction drives the rotation of worm gear clockwise direction, and this moment, this gear-box was positive rotation; When needs change the gear-box rotation direction, only need worm screw is packed into from the other end, at this moment, worm screw clockwise rotates, and the drive worm gear rotates counterclockwise, thereby has changed the rotation direction of gear-box, and promptly gear-box is rotated counterclockwise.
Beneficial effect: a kind of worm and gear gear-box provided by the invention; In worm screw can be packed casing into from any mount inlet; Make things convenient for the user to change input, output rotation direction according to actual needs, realized adopting same casing, the purpose of the gear-box of two rotation directions of assembling; Reduce cost, improved economic benefit.

Embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
As shown in Figure 1, this gear-box comprises the casing 1 of symmetrical configuration, is respectively equipped with mount inlet 2 at these casing 1 two ends; Two ends at casing 1 inwall are provided with groove 3 symmetrically, during installation, earlier with mount inlet 2 encapsulation of a case lid 8 with casing 1 one ends; The first cone angle contact bearing 5 of packing into then, this first cone angle contact bearing 5 is adjacent to case lid 8, is formed the platform that supports this first cone angle contact bearing 5 by this case lid 8; Behind the worm screw 4 of packing into; Because worm screw 4 is provided with flange 401, cooperate above-mentioned platform, this first cone angle contact bearing 5 of reality spacing.
Pack into behind the worm screw 4, pack opened gap circle 7 into casing 1 from the mount inlet 2 of the other end in, as shown in Figure 2 owing to be circular at this opened gap circle 7; And have opening 701, only need its annulus surface is applied the pressure towards the center of circle, this opened gap circle 7 gets final product compressive strain, in the casing 1 of conveniently packing into; Simultaneously, as shown in Figure 3, the surface is provided with the compartment of terrain and is provided with two boss 702 above that; And described boss 702 matches with groove 3 on casing 1 inwall, in opened gap circle 7 is packed casing 1 into after, make boss 702 snap in groove 3; Remove then its applied pressure, make its shape reduction, fastening the snapping in the groove 3 of these boss 702 abilities; This groove 3 can be processed into whole ring structure, also can be processed into the segmented ring structure.
Be inserted in the second cone angle contact bearing 6 again after installing opened gap circle 7; This second cone angle contact bearing 6 is positioned at opened gap circle 7 and worm screw 4; With after another mount inlet 2 usefulness case lids 8 encapsulation, case lid 8 cooperates the flange 401 on the worm screw 4 to realize the spacing of the second cone angle contact bearing 6 again;
Thereby, the symmetrical worm screw 4 of implementation structure guarantees that this structure realizes two-way rotation for being fit in the casing 1 from any end; This casing 1 is symmetrical structure; Simultaneously; The integral body that described second cone angle contact bearing 6 and opened gap circle 7 form and the symmetrical configuration of the first cone angle contact bearing 5 promptly require the described second cone angle contact bearing 6 and the internal diameter and the external diameter of the integral body of opened gap circle 7 formation to equate with the internal diameter and the external diameter of the symmetrical configuration of the first cone angle contact bearing 5.
Technical conceive of the present invention and characteristics its objective is to let and are familiar with these those skilled in the art and can understand content of the present invention and implement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit has been done according to the present invention or modification all should be encompassed within protection scope of the present invention.
