Abstract
The utility model relates to a reducer, in particular to a reducer for stone equipment, which mainly solves the technical problem in the prior art that when the existing reducer is used for the stone equipment, dust and scraps are easy to enter inside a box body through connector gaps of all parts of the reducer, thereby leading a worm gear and a worm to be blocked, shortening service life and the like. The reducer for the stone equipment comprises the box body (1) and is characterized in that the worm (2) is connected to the lower portion of the box body (1) in penetrating mode, an input flange (3) is connected to the lower portion of the box body, the worm extends into the input flange, the worm gear (4) is arranged in the middle of the worm in meshed mode, a worm gear shaft (6) is fixed in the middle of the worm gear through a flat key (5), a big end cover (7) is connected to the upper portion of the box body, the end portion of the worm gear shaft extends out of the big end cover, and a first oil seal (8) is arranged between the big end cover and the worm gear shaft.
Description
Technical field
The utility model relates to a kind of speed reducer, especially relates to a kind of speed reducer that is used for stone material equipment.
Background technique
At present; Miniature gear speed reducer, the worm-gear speed reducer of being used widely; Receive volume restrictions, its speed ratio is less than normal, and its transmission direction is generally parallel input output and can not satisfies some existing large speed ratios mini-plant that has vertical transmission direction to require again that slows down and install and use.Chinese patent discloses a kind of double worm and gear speed reducer structure (notice of authorization number: CN 201250880Y); It comprises worm type of reduction gearing; Be provided with two worm type of reduction gearings; Worm screw on two worm type of reduction gearings links together through the coupling of axial rotation adjustable angle, realizes synchronization; Have at least one worm screw two ends all to stretch out in himself reducer shell in two worm type of reduction gearings, with a end that coupling is not installed on this worm screw input shaft as this reducing gear; Output shaft on each worm type of reduction gearing is connected with a small gear respectively; Small gear simultaneously and the gearwheel engagement driving, and with the transmission shaft at gearwheel place output shaft as this reducing gear; The two ends of the worm screw of two worm type of reduction gearings all stretch out in the housing of retarder itself separately; Two worm type of reduction gearings and connected small gear respectively; Have identical specification respectively, the coupling of employed axial rotation adjustable angle is made up of two half-couplings, and some screws evenly distribute on one of them half-coupling; Corresponding described screw is provided with the slotted hole of some arcs on another half-coupling, is fastenedly connected through screw between two half-couplings.When but this retarder was used on the stone material equipment, the dust chip entered into box house through the place, interface slit of each component of speed reducer easily, thereby can cause worm and gear stuck, influences the working life of speed reducer.
The model utility content
The utility model provides a kind of speed reducer that is used for stone material equipment; It mainly is when solving the existing in prior technology retarder and being used on the stone material equipment; The dust chip enters into box house through the place, interface slit of each component of speed reducer easily; Thereby can cause worm and gear stuck, influence the technical problem in working life etc. of speed reducer.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of speed reducer that is used for stone material equipment of the utility model comprises casing, and described lower box cross-under has worm screw; Lower box is connected with input flange, and worm screw stretches in the input flange, and the worm screw middle part is engaged with worm gear; Be fixed with worm-wheel shaft through flat key in the middle of the worm gear; Casing top is connected with big end cap, and stretch out outside the big end cap worm-wheel shaft end, and is provided with first oil sealing between big end cap and the worm-wheel shaft.Behind the worm screw input power, promptly begin to rotate with the worm gear of its engagement, worm-wheel shaft is given in last transmission, and worm-wheel shaft can be connected with miscellaneous equipment through flat key.The bottom of casing can be provided with purge cock, and the top of casing can be provided with breather.In the assembling slit of worm-wheel shaft and big end cap, add oil sealing, can prevent that on the one hand the fluid in the casing from leaking outside, can prevent also that on the other hand the outside dust and other impurities of speed reducer from invading speed reducer inside.Oil sealing can have nitrile butadiene rubber to process.
As preferably, be provided with second oil sealing between described worm screw one end and the input flange.Second oil sealing can prevent that the fluid in the casing from leaking outside, and also can prevent that the outside dust and other impurities of speed reducer from invading speed reducer inside simultaneously.
As preferably, all be provided with clutch shaft bearing between the two ends of described worm-wheel shaft and the casing.Can make that like this worm-wheel shaft is more smooth and easy rotatably.
As preferably, all be provided with second bearing between two ends of described worm screw and the casing.Can make that like this worm screw is more smooth and easy rotatably.
Therefore; The utility model adds oil sealing through big end cap, the input flange place at speed reducer, can prevent that the dust chip from entering into box house through the place, interface slit of each component of speed reducer, thereby prevent that worm and gear is stuck; The working life of speed reducer is longer, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model;
Accompanying drawing 2 is side structure schematic representation of Fig. 1.
Component, position and numbering among the figure: casing 1, worm screw 2, input flange 3, worm gear 4, flat key 5, worm-wheel shaft 6, big end cap 7, first oil sealing 8, second oil sealing 9, clutch shaft bearing 10, second bearing 11.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
Embodiment: a kind of speed reducer that is used for stone material equipment of this example like Fig. 1, Fig. 2, has a casing 1; The lower box cross-under has worm screw 2; Lower box is connected with input flange 3, and worm screw stretches in the input flange, is provided with second oil sealing 9 between worm screw one end and the input flange.All be provided with second bearing 11 between two ends of worm screw and the casing.The worm screw middle part is engaged with worm gear 4, is fixed with worm-wheel shaft 6 through flat key 5 in the middle of the worm gear, and casing top is connected with big end cap 7, and stretch out outside the big end cap worm-wheel shaft end, and is provided with first oil sealing 8 between big end cap and the worm-wheel shaft.All be provided with clutch shaft bearing 10 between the two ends of worm-wheel shaft and the casing.
During use, worm screw 2 places input power, worm screw drives worm gear 4 rotations, and the worm-wheel shaft 6 that worm gear connects is connected with miscellaneous equipment through flat key, can give miscellaneous equipment with transmission of power after the worm gear rotation.
