Abstract
The utility model relates to a reducer part, and in particular relates to a reducer wear-resistant worm wheel provided with an oil storage tank. The technical problems in the prior art that the tooth surface of the worm wheel is burned even a tooth part falls off, and the service life of the reducer is seriously reduced, and the like, due to a fact that the no-oil friction is likely to happen when the worm wheel is engaged with a worm because only a little lubricating oil is remained on the tooth surface of the worm wheel when the worm transmits on the worm wheel, are mainly solved. The reducer wear-resistant worm wheel comprises a worm wheel core (1), and is characterized in that a worm wheel tooth part (2) is arranged on the outer circle of the worm wheel core (1); the worm wheel tooth part comprises a plurality of worm wheel tooth surfaces (3) which are arranged at intervals and a worm wheel tooth root (4), wherein a worm wheel oil storage tank (5) is arranged on the worm wheel root.
Description
Technical field
The utility model relates to a kind of speed reducer component, especially relates to a kind of speed reducer abrasion resistant worm wheel with oil storage tank.
Background technique
Worm gear is the critical piece of worm reduction gear, and affect the most crucial parts in speed reducer life-span, is also worm gear.Due to the particularity of Worm Wheel System, during engagement, there is high-speed friction, so the tooth portion of worm gear the most easily weares and teares.Chinese patent discloses a kind of double worm gear reducing mechanism (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 by the adjustable coupling of axial rotation angle, realizes synchronization; In two worm type of reduction gearings, have at least the worm screw two ends of all to stretch out in himself reducer shell, using on this worm screw and one end of coupling is not installed as the input shaft of this reducing gear; Output shaft on each worm type of reduction gearing is connected with respectively a small gear; Small gear simultaneously and gearwheel engagement driving, and is usingd the transmission shaft at gearwheel place as the output shaft of 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 respectively connected small gear, there is respectively identical specification, the adjustable coupling of axial rotation angle using consists of two half-couplings, on one of them half-coupling, be uniformly distributed some screws, on another half-coupling, corresponding described screw is provided with the slotted hole of some arcs, between two half-couplings, by screw, is fastenedly connected.But this speed reducer adopts Cuprum alloy casting worm-gear tooth portion gear hobbing processing more, but friction produces a large amount of heat, and greatly reduced the working life of worm gear.Particularly worm screw is above worm gear in transmission, and lubricant grease is trapped in the worm gear flank of tooth seldom, easily makes worm and gear when engagement produce without oil drag, causes worm gear flank of tooth burn, and even tooth portion comes off, and seriously shortens speed reducer working life.
Model utility content
The utility model is to provide a kind of speed reducer abrasion resistant worm wheel with oil storage tank, it is mainly to solve the existing worm screw of prior art above worm gear in transmission, lubricant grease is trapped in the worm gear flank of tooth seldom, while easily making worm and gear engagement, produce without oil drag, cause worm gear flank of tooth burn, even tooth portion comes off, the technical problem that seriously shortens speed reducer working life etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of speed reducer abrasion resistant worm wheel with oil storage tank of the present utility model, comprises worm gear core wheel, and the cylindrical of described worm gear core wheel is provided with worm-gear tooth portion, and worm-gear tooth portion includes the worm gear flank of tooth and worm gear tooth root alternately, and worm gear tooth root is provided with worm gear oil storage tank.The utility model has been processed oil storage tank at each tooth root place of worm gear, has the function that stores lubricant grease.When worm gear is immersed in lubricant grease, during due to design, the breadth depth ratio example of oil storage tank has been met to the capillary phenomenon formation condition of lubricant oil, therefore worm gear tooth root oil storage tank can suck lubricant grease.When the speed reducer worm screw of High Rotation Speed, drive subsequently the moment of worm gear rotation, the lubricant grease in oil storage tank can be thrown to the worm gear flank of tooth along with air-flow, is worm and gear flank engagement spot lubrication in time, greatly improves the wear-resisting property of worm gear.
The processing method of oil storage tank: adopt the hobboing cutter with special modification coefficient to carry out slot rolling processing, its operation is generally carried out after worm gear hobbing operation.
In addition, between worm-gear tooth portion and worm gear core wheel, be to be formed by connecting by the casting of large rectangle tooth, strengthened the join strength of worm-gear tooth portion and worm gear core wheel, and the rigidity that has ensured worm-gear tooth portion.
As preferably, the two ends of described worm gear oil storage tank flush with worm gear tooth root, the darkest during the recessed middle part to worm gear tooth root gradually.
As preferably, the normal direction width of described worm gear oil storage tank is less than the normal direction width of worm gear tooth root, and the degree of depth of groove, width and length must lengthen being not enough to affect under the prerequisite of worm-gear tooth portion intensity as far as possible.The direction call vertical with worm wheel helical line to, normal direction is the direction of normal, and tangentially, the direction of tangent line is vertical.
Therefore, the utility model has been processed oil storage tank at each tooth root place of worm gear, there is the function that stores lubricant grease, when the speed reducer worm screw of High Rotation Speed drives moment of worm gear rotation, lubricant grease in oil storage tank can be thrown to the worm gear flank of tooth along with air-flow, be worm and gear flank engagement spot lubrication in time, greatly improve the wear-resisting property of worm gear, simple and reasonable for structure.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is a kind of structural representations of the utility model worm gear oil storage tank intermediate cross-section.
Component, position and numbering in figure: worm gear core wheel 1, worm-gear tooth portion 2, the worm gear flank of tooth 3, worm gear tooth root 4, worm gear oil storage tank 5.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of speed reducer abrasion resistant worm wheel with oil storage tank of this example, as shown in Figure 1, Figure 2, comprise worm gear core wheel 1, the cylindrical of worm gear core wheel is provided with worm-gear tooth portion 2, worm-gear tooth portion includes the worm gear flank of tooth 3 and worm gear tooth root 4 alternately, and worm gear tooth root is provided with worm gear oil storage tank 5.The two ends of worm gear oil storage tank flush with worm gear tooth root 4, the darkest during the recessed middle part to worm gear tooth root gradually.The normal direction width of worm gear oil storage tank is less than the normal direction width of worm gear tooth root 4.
During use, whole worm gear is installed in speed reducer.
