Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 1 and composition graphs 2 to Fig. 4, a kind of insulation planet stent that the utility model embodiment provides, it comprises the chassis 1 of being made up of insulating material, be socketed with an axle tooth 2 be made up of metallic material at the place of bottom center on chassis 1, (it is according to planetary requirement to be socketed with the equally distributed supporting post of several threaded shaft teeth 3 on the surface, be traditionally arranged to be three), on the surface on chassis 1, to the position of the root being positioned at axle tooth 2, be provided with embedded slot simultaneously, in embedded slot, be filled with insulation glue-line 4.So, planet stent can be utilized to install planetary pinion, the chassis 1 of insulation and insulation glue-line 4 is utilized to ensure that whole support has good insulation effect, when whole support and the planetary pinion equipped with it are installed in gear-box, insulation can be realized from the inside of gear-box, effectively prevent gear-box and easily occur the safety problems such as electric leakage.
For ensureing the soundness of whole supporting structure, realize the integral structure between constituent elements, axle tooth 2 is provided with one first convex edge 5, accordingly, the underside side on chassis 1 is provided with the first annular groove with the first convex edge 5 contraposition cutting ferrule; Offer the second annular groove at the root of supporting post 3, accordingly, in chassis 1, be provided with the second convex edge 6 with the second draw-in groove contraposition cutting ferrule, thus ensure that the parts of different materials can carry out firm assembling, improve whole between structural strength.
For reducing the cost of whole support, reach good insulation effect, the preferred plastic material of material on the chassis 1 of the present embodiment simultaneously.
Based on the structural characteristics of above-mentioned planet stent, as shown in Figures 2 to 4, the present embodiment additionally provides a kind of oil-leakage-prevention low-noise planetary case, and it comprises the internal tooth casing 7 inwall being provided with internal tooth arrangement and the input stage sun tooth 8, planet assembly and the output stage planet stent 9 that are installed in successively along Power output direction in internal tooth casing; Wherein, planet assembly comprises at least two planetary gear set a (each planetary gear set a is formed around the equally distributed gear in its axle center by three), be provided with a middle planetary support b between two adjacent planetary gear set, the middle planetary support b of the present embodiment is above-mentioned a kind of insulation planet stent; With this, the axle tooth 2 of middle planetary support b is plugged in the planetary gear set a that is positioned at its underside side and planetary gear set a is meshed therewith, the planetary gear set a being positioned at the surface side of middle planetary support b is then set on the supporting post 3 of middle planetary support b, the planetary gear set a adjoining with output stage planet stent 9 to be installed on output stage planet stent 9 and to be meshed with the internal tooth of internal tooth casing 7, and 8, input stage sun tooth is plugged in and is adjacent near planetary gear set a and planetary gear set a is meshed therewith.Thus, multistage (multiple) planetary gear set a can be assembled successively by the middle planetary support b be installed in internal tooth casing 7, not only can realize good insulation effect from the inside of internal tooth casing 7, ensure the safe operation of gear-box, and the gear-box with multistage or different drive ratios can be made according to specific needs.
For strengthening the oil-leakage-prevention effect of gear-box, between output stage planet stent 9 and planetary gear set a, be clamped with grease proofing pad 10.As a preferred version, the fluted disc that the grease proofing pad 10 of the present embodiment adopts to have a central shaft hole, grease proofing pad 10 is meshed with the internal tooth of internal tooth casing 7.Thus, by adopting fluted disc structure, ensure that gear-box can have the good effect preventing grease seepage in running.
For improving the insulation effect of gear-box inside further, between the underside side and planetary gear set a of middle planetary support b, be clamped with the root that the anticreep pad 11 of the anticreep pad of at least one deck first 11, first is socketed on the axle tooth 2 of planetary gear set a; Simultaneously, the anticreep pad 12 of at least one deck second is then clamped with between the surface side and planetary gear set a of middle planetary support b, second anticreep pad 12 is socketed on the supporting post 3 of planetary gear set a, with this, can effectively prevent electric leakage from puncturing, be delivered to gear-box when stopping motor electric leakage, thus dangerous hidden danger is produced to people.
In addition, be made up of nylon gear with the planetary gear set a that input stage sun tooth 8 is adjoining, to improve the anticreep performance punctured further.
For effectively reducing the noise of whole gear-box, internal tooth casing 7 sidewall pressed on ring week be provided with several sound insulation chambeies 13, the opening direction in sound insulation chamber 13 contrary with the Power output direction of internal tooth casing 7 (namely towards one end of input stage sun tooth 8); So, when noise transmission, most of noise can be absorbed by multiple sound deadening space be made up of sound insulation chamber 13, can effectively reduce the resonance noise produced in gear-box running.
For improving the intensity of gear-box total, the gear-box of the present embodiment can adopt following specific design, that is: two-stage planet group a (namely two) is adopted, the number of teeth of internal tooth casing 7 is set to 52T, the number of teeth of the gear of planetary gear set a is set to 22T, the number of teeth of input stage sun tooth 8 is set to 8T, thus the two stage speed change that gear-box is had is than being 1:56.25; And all tooth-formation of gear all adopt the non-standard pressure angle of 24 degree, and the internal tooth of internal tooth casing 7 and input stage sun tooth 8 are all added with rotating forward potential coefficient; So, suitable gear ratio, special pressure angle add appropriate transposition coefficient, through overtesting, can solve the gearing noise often occurred because conventional planetary gear case adopts standard tooth form to greatest extent, and increase by the intensity of 35% than conventional gearbox.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
