Abstract
The utility model discloses a gear transmission device for power connection of an air compressor and a gear chamber. The gear transmission device comprises a main gear box; a middle transmission shaft is in rotating connection with the inside of the main gear box; the section of the middle transmission shaft, which is exposed out of the main gear box, is in power connection with a middle transmission gear which can be meshed with an output gear arranged on the gear chamber; the section of the middle transmission shaft, which is located in the main gear box, is fixedly connected with a power output gear; an installation chamber for a power input gear of the air compressor to extend into is formed in the main gear box. According to the gear transmission device for the power connection of the air compressor and the gear chamber, a gear train and the gear chamber do not need to be redesigned, the installation position of the air compressor does not need to be designed out, and the large change does not need to be performed on the original engine when the air compressor is added and accordingly the production cost is saved, the modification cycle is greatly reduced, and the transmission is stable.
Description
Technical field
The utility model relates to the gear drive that a kind of air compressor is connected with gear chamber power.
Background technique
The layout of air compressor has two kinds substantially at present: one is directly fixed in gear chamber by flange, and air compressor direct geared is by the gear drive in gear chamber; Another kind is belt transmission, air compressor is fixed on support, drives by belt, and these two kinds of arrangements respectively have pluses and minuses, the former transmission is stable but have output gear and the unmatched problem of rotational speed of air compressor of gear-box, and the latter exists the unsettled shortcoming of transmission.On original motor basis, install air compressor additional, if do not reserve in advance the interface of air compressor, in the time arranging the air compressor of gear transmission mode, generally can run into the problem of air compressor difficult arrangement.The method solving is to redesign train of gearings, gear chamber, designs the mounting point of air compressor, and whole train of gearings, gear chamber are redesigned, and also may relate to the change of other component.Namely will do larger variation to original motor, could realize the layout of air compressor, the cost of increase and manufacture cycle are all long.
Model utility content
The gear drive that the utility model provides a kind of air compressor to be connected with gear chamber power for the problems referred to above, after air compressor being connected with gear chamber power by this device, transmission is stable and guarantee that rotational speed of air compressor reaches regulation requirement.
In order to solve the problems of the technologies described above, the gear drive that the utility model provides a kind of air compressor of following structure to be connected with gear chamber power, comprise main-gear box, in main-gear box, be rotatably connected to middle biography axle, middle biography axle exposes power in portion's section of main-gear box and is connected with the middle biography gear that can engage with the output gear in gear chamber, middle biography axle is positioned in portion's section of main-gear box and is also connected with power output gear, is also provided with the installation cavity stretching into for the power input gear of air compressor in main-gear box.
Described main-gear box is made up of upper box lid and the lower box of matched together, and described middle biography axle is through upper box lid and have exposed division section, and described lower box is provided with ring convex edge, and ring convex edge is provided with multiple threaded connection holes.
Described middle biography gear is connected in the exposed division section of middle biography axle and is bolted with the nut being pressed against on middle biography gear on middle biography axle by key.
Adopt after said structure, engage outputting power by middle biography gear with the output gear in gear chamber, by middle biography axle, power output gear the most at last transmission of power to air compressor, driving air compressor rotary work; According to appropriate design gear ratio, guarantee that rotational speed of air compressor reaches regulation requirement simultaneously.While adopting said structure to install air compressor additional, the mounting point that no longer needs to redesign train of gearings, gear chamber and design air compressor, no longer need original motor to do larger variation, saved cost of production and greatly reduced the repacking cycle, and having had advantages of that transmission is stable.
Accompanying drawing explanation
Fig. 1 is a kind of embodiment's of the present utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
As shown in Figure 1, the gear drive that air compressor provided by the utility model is connected with gear chamber power comprises main-gear box 1, main-gear box 1 is made up of upper box lid 11 and the lower box 12 of matched together, between upper box lid 11 and lower box 12, seal ring is housed, described middle biography axle 2 is through upper box lid 11 and have exposed division section, described lower box 12 is provided with ring convex edge 13, ring convex edge 13 is provided with multiple threaded connection holes, thereby can, at the air compressor support of position installation easily, this main-gear box 1 be fitted on support.In main-gear box 1, be rotatably connected to middle biography axle 2, the upper and lower of middle biography axle is connected in main-gear box 1 by deep groove ball bearing respectively, middle biography axle 2 exposes power in portion's section of main-gear box 1 and is connected with the middle biography gear 3 that can engage with the output gear in gear chamber, middle biography axle 2 is positioned in portion's section of main-gear box 1 and is also connected with power output gear 4, in main-gear box 1, be also provided with the installation cavity 5 stretching into for the power input gear of air compressor, installation cavity 5 is roughly cylindrical, there is shown the power input gear 8 of air compressor.Middle biography gear 3 is connected in the exposed division section of middle biography axle 2 and is bolted with the nut 6 being pressed against on middle biography gear 3 on middle biography axle 2 by key.
The utility model not only limits the use of in equipped air compressor on motor, adapts to the equipped of such as sea water pump, heat exchanger etc. thereby installation cavity 5 also can change shape.
The above is specific constructive form of the present utility model; the utility model is not restricted to the described embodiments; the art personnel, the equivalent variations based on concrete structure on the utility model and parts are replaced all in protection domain of the present utility model.
