“…Cui [12] and Zhang [13] have stated that this type has relatively high cost, the poor resistance to earthquakes performance and the torque is constrainted by the strength of the permanent magnet, etc. Zhao [14] and Ma [15] also think that the linear motor reciprocating drainage machine has the problem of high cost and difficult maintenance. Correspondingly, the compound permanent magnet motor and the linear motor reciprocating machines, shown in Figures 3 and 4, are all drainage machines of the motor reversing type.…”

Abstract:In order to solve the problem of reciprocating motion in no beam supported mining machines, putting energy saving as a starting point in Coal Bed Methane (CBM) exploitation, this paper designs a completely non-circular gear automatic reversing vertical drainage machine based on the theory of non-circular gear transmission. In the field of CBM exploitation, the use of non-circular gears is an attempt at an innovation. First of all, according to the working conditions of the pump and use requirements, a scheme is established whereby the one-way rotary motion of the motor is changed into reciprocating motion so that it could drive the oil pumping rod to achieve the upper and lower mining. Secondly, this paper has designed a new type non-circular gear reversing box as the core component to replace the traditional four beam linkage mechanism and also provides elaborate calculations. Finally, the movement simulation of the non-circular gear reversing gear system is completed. Comparing the motion simulation results with the theoretical ones, the correctness of our theoretical analysis can be verified. Compared with the traditional devices, the new coal seam gas drainage machine model design has nearly 11% higher efficiency, which has obvious energy saving effects and reduces the cost of mining coal seam gas.
