Abstract
The utility model discloses a speed reducer for a coal cutter, which comprises a sealing shell, a speed changing gear meshed with a motor, a gear shaft, a principal shaft and a chain wheel. The gear shaft and the principal shaft are spanned in the sealing shell; the speed changing gear is sleeved on the gear shaft; the principal shaft is provided with a gearwheel which is meshed and connected with the gear shaft; one end of the principal shaft extends out of the sealing shell; and the chain wheel is sleeved on the principal shaft which extends out of the sealing shell. The speed reducer is small in size and adopts two steps of speed change through gears and selects a 4-grade motor as the power source, thus reducing the size and satisfying the requirement of cutting the coal at the ultra-thin coal bed.
Description
Technical field
The utility model relates to a kind of coal cutter retarder.
Background technique
Existing coal cutter retarder adopts the transmission of bevel gear one-level speed change, and gear ratio is less, therefore must adopt more than 6 grades motor as motive force, so profile is bigger, can not satisfy ultra-thin coal seam coal cutting demand.
The model utility content
The purpose of this utility model provides a kind of coal cutter retarder, and this coal cutter reducer structure is simple, easy to use, the effect height.
For solving the problems of the technologies described above, technological scheme provided by the utility model is: a kind of coal cutter retarder, this coal cutter retarder include seal casinghousing, with speed change gear, gear shaft, main shaft and the sprocket wheel of motor engagement, described gear shaft and main shaft are erected in the seal casinghousing, and described speed change gear is set on the gear shaft; Described main shaft is provided with gearwheel, and described gearwheel and gear shaft are connected with a joggle; Described main shaft one end stretches out seal casinghousing, and described sprocket wheel is set on the main shaft that stretches out seal casinghousing.
The advantage that the utlity model has: profile is little, adopts the two-stage gear graduation, and selects for use 4 grades of motors as motive force, has reduced boundary dimension, can satisfy ultra-thin coal seam coal cutting demand.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Embodiment:
A kind of coal cutter retarder as shown in Figure 1, this coal cutter retarder include seal casinghousing 1, with speed change gear 2, gear shaft 21, main shaft 3 and the sprocket wheel 4 of motor engagement, described gear shaft 21 and main shaft 3 are erected in the seal casinghousing, and described speed change gear 2 is set on the gear shaft 21; Described main shaft 3 is provided with gearwheel 31, and described gearwheel 31 is connected with a joggle with gear shaft 21; Described main shaft 3 one ends stretch out seal casinghousing 1, and described sprocket wheel 4 is set on the main shaft 3 that stretches out seal casinghousing 1.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction; though the utility model discloses as above with preferred embodiment; yet be not in order to limit the utility model; any those skilled in the art; in not breaking away from the technical solutions of the utility model scope; when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations; in every case be the content that does not break away from technical solutions of the utility model; according to technical spirit of the present utility model to any simple modification that above embodiment did; equivalent variations and modification all still belong to the protection domain of technical solutions of the utility model.
