Abstract
The utility model relates to a steel ball worm wheel box which effectively solves the problems of low intensity, low safety coefficient, high cost and time/labor consuming. The technical scheme of the steel ball worm wheel box is as follows: the steel ball worm wheel box comprises a worm wheel, a worm screw and a box body; the worm screw which adopts an integral structure is arranged at one side of the box body, grooves which are mutually corresponding to the grooves on the outer parts at the two ends of the worm screw are arranged in the box body, steel balls are arranged in the two opposite grooves, the grooves are communicated with a screw hole channel, the upper end part of the screw hole channel is communicated with a pressing and oiling cup on the box body, the worm wheel meshed with the worm screw is arranged in the box body, an indicating keyboard is arranged at the upper end of the worm wheel, and a hand wheel is arranged on the end part of the worm screw stretching out of the box body. With the characteristics of firm as well as reliable structure, material saving, small volume, light weight, convenient as well as quick installation and long service life, the steel ball worm wheel box is an innovation on a worm wheel driving device.
Description
One, technical field
The utility model relates to the worm-gear driven device, particularly a kind of steel ball Worm gear case.
Two, background technique
Worm gear case is a kind of the most frequently used, the most general drive unit, and the domestic and international market kind is ever-changing, have Americanly abroad, domestic have Tianjin, Shanxi, the Zi Gong, Wenzhou or the like, the most influential is the Worm gear case that the U.S. produces, advantage is: compact structure, no end cap, the casting of casing centreless, cost is low, and shortcoming is: worm screw adopts axle sleeve type intensity low, does not allow overload, comparatively safe coefficient is little, and appearance design is not very attractive in appearance.The present domestic American structure production of much copying in addition, wherein formula Worm gear case in Shanxi is exactly imitative U.S. produced, the domestic Worm gear case intensity height that has only several minorities to produce now, safety coefficient is big, and adopting whole worm screw to rotate stressed with respect to worm gear case is centripetal force.When the stressed overload of worm screw, also be difficult for worm gear case is damaged.In order to accomplish the end in view, interstage sleeve, divided ring, bearing, end cap have all been designed at the worm gear case two ends.The Worm gear case cost of this structure is higher, and time-consuming effort again is so its improvement is imperative.
Three, model utility content
At above-mentioned situation, for overcoming the prior art defective, the purpose of the utility model just provides a kind of steel ball Worm gear case, it is low effectively to solve intensity, safety coefficient is little, and cost is higher, the time-consuming problem of effort again, the technological scheme of its solution is, comprise worm gear, worm screw and casing have integrally-built worm screw in casing one side, are provided with in the casing and the mutual corresponding groove of the outside upper groove in worm screw two ends, in the two relative grooves steel ball is arranged, groove and silk hole path are connected, and the forced filling oil cup on silk hole path upper end portion and the casing is connected, and the worm gear that is meshed with worm screw is arranged in the casing, there is indication arrow dish worm gear upper end, and worm screw stretches out on the end of casing is equipped with handwheel.The utility model sound construction is reliable, saves material, and volume is little, and is in light weight, and it is convenient to install, and long service life is the innovation on the worm-gear driven device.
Four, description of drawings
Fig. 1 is a section of structure of the present utility model.
Fig. 2 is a structural front view of the present utility model.
Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Provide by Fig. 1-Fig. 2, the utility model comprises worm gear, worm screw and casing, integrally-built worm screw 12 is arranged in casing 1 one sides, be provided with in the casing and the mutual corresponding groove 9 of the outside upper groove in worm screw two ends, in the two relative grooves steel ball 2 is arranged, groove and silk hole path 11 are connected, forced filling oil cup 3 on silk hole path upper end portion and the casing is connected, the worm gear 5 that is meshed with worm screw 12 is arranged in the casing 1, there is indication arrow dish 6 worm gear 5 upper ends, worm screw stretches out on the end of casing is equipped with handwheel 13, in 12 liang of relative grooves 9 of casing 1 and whole worm screw steel ball 2 is housed, play the effect of bearing first, worm screw 12 two ends and casing 1 contacting point no longer are provided with bearing (replacement bearing), second limiting worm screw 12 can only rotate, can not axial float, no matter worm screw 12 is clockwise or rotates counterclockwise with respect to the casing 1 stressed centripetal force that is all, and when worm screw 12 stressed overloads, also is difficult for worm gear case 1 is damaged, for reaching this purpose of design, this new structure need not to make end cap, and is preceding, back interstage sleeve, and divided ring, so there be ' ball ' that the effect of end cap is not only arranged, the merit that also has interstage sleeve, and also have energy of rolling bearing, so be called the steel ball Worm gear case.
In order to guarantee using effect, the case lid 4 that is installed on the worm gear periphery is arranged at said casing 1 top, and case lid is fixed on the casing through cover bolt 8; Have on the said casing and put in the casing screw 10 that box house is adjusted the worm gear angle of swing; Said indication arrow dish 6 is fixed on through plus screw 7 and is used for showing the worm gear angle of swing on the worm gear; Said casing inner groovy and groove on the outside, worm screw two ends are identical square of size, not only can store steel ball 2, also help storage lubricant oil; Said forced filling oil cup 3 diameters are greater than steel ball 2 diameters; Said handwheel 13 is fixed on the worm screw outer end through packing ring 15 and flat key 16 by handwheel bolt 14.
The utility model utilizes bearing and the structural principle of splitting card, developed steel ball structure and changed a kind of new structure Worm gear case that worm screw is subjected to force direction, this new structure does not have end cap and connects the bolt of end cap, forward and backward interstage sleeve, split card, bearing, after removing described part, worm screw is to adopt overall structure, non-axle sleeve structure, no matter worm screw is when being subjected to positive interaction power or reaction force, and for worm gear case, worm gear case is stressed all to be centripetal force.Be exactly worm screw overburdening rotation under special circumstances, also be not interposing at worm gear case and worm screw are damaged.So overall structure is solid and reliable, save material and work time cost simultaneously more than 25%, it is little, in light weight to have a volume, and it is convenient to install, advantages such as long service life, economic and social benefit is remarkable.
