Abstract
The utility model relates to a gear especially relates to a mining machinery is input gear for speed reducer. It mainly is that to solve the gear structure that speed reducer that prior art exists adopted comparatively complicated, installs comparatively difficultly, and transmission efficiency is lower, and manufacturing cost is higher to intensity is relatively poor, and the resiliency is lower, technical problem that life is short etc.. The utility model discloses a gear body (1), the excircle of gear body (1) be equipped with denticle (2), open the inside of gear body (1) has oiling groove (3), the terminal surface and the shaft hole of oiling groove intercommunication gear body, oiling groove is the slant setting.
Description
Technical field
The utility model relates to a kind of gear, especially relates to a kind of mining machinery speed reducer input gear.
Background technique
Speed reducer is drive by motor the machinery realizing transmitting retarding power in mechanical transmission, and it and machine tool are connected, and its machine tool relates to the fields such as metallurgy, mine, wooden industry, digging.Chinese patent discloses a kind of bidirectional output speed reducer (publication number: CN101761609A), comprise input tooth axle, input gear, output gear, oil pump gear, oil pump, casing and case lid composition, input gear is arranged on input tooth axle, and intermeshes with output gear; Oil pump gear and oil pump are meshed and input tooth axle and engage, and drive oil pump to export lubricant oil; Export and be speed increasing ratio with the gear ratio of input gear, casing adopts split type weldment, postwelding destressing process sandblasting, casing mating face 0.25-0.85cm longer than case lid, input end is frequency control of motor speed, and bidirectional output speed reducer can unidirectionally export, bidirectional output speed reducer output speed is up to 5000 revs/min, oil pump exports lubricant oil, makes each section of bearing run up obtain pressure lubrication and cooling, ensures that speed reducer runs well.But the gear structure that this speed reducer adopts is comparatively complicated, install comparatively not easily, transmission efficiency is lower, and cost of production is higher, and intensity is poor, and resiliency is lower, and working life is shorter.
Model utility content
The utility model is to provide a kind of mining machinery speed reducer input gear, its gear structure mainly solving the speed reducer employing existing for prior art is comparatively complicated, install comparatively not easily, transmission efficiency is lower, cost of production is higher, and intensity is poor, resiliency is lower, working life shorter grade technical problem.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Mining machinery speed reducer input gear of the present utility model, comprise gear, the cylindrical of described gear is provided with denticle, and the inside of gear has oiling groove, and oiling groove is communicated with end face and the axis hole of gear, and oiling groove is oblique setting.Can carry out lubricated to gear at any time by oiling groove, the oblique setting of oiling groove, can not affect the intensity of whole gear.
As preferably, in the axis hole of described gear, be provided with the step that more than 3 internal diameters are different.By different steps, intermediate gear can be made can to select the transmission shaft of dress different size, and Applicable scope is wider.
As preferably, the end face at described gear two ends all has dashpot, is provided with shock absorber in dashpot, the outer surface of shock absorber is provided with sawtooth.By shock absorber, can ensure that output gear operationally can play the effect of buffering, prevent it from beating excessive.
Therefore, the utility model arranges oiling groove on gear, whole gear operationally can be lubricated, thus make transmission efficiency higher, and arrange step in gear, makes assembling Applicable scope comparatively wide, 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 cross-sectional view of Fig. 1.
Component, position and numbering in figure: gear 1, denticle 2, oiling groove 3, step 4, dashpot 5, shock absorber 6.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the mining machinery speed reducer input gear of this example, as shown in Figure 1, Figure 2, comprises gear 1, the cylindrical of gear is provided with denticle 2, the inside of gear has oiling groove 3, and oiling groove is communicated with end face and the axis hole of gear, and oiling groove is oblique setting.The step 4 that more than 3 internal diameters are different is provided with in the axis hole of gear.The end face at gear two ends all has dashpot 5, is provided with shock absorber 6 in dashpot, the outer surface of shock absorber is provided with sawtooth.
During use, the utility model is encased in mining machinery speed reducer.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed among the scope of the claims of the present utility model.
