Abstract
The utility model discloses a speed reducer transmission device for a double-spiral drilling machine. The speed reducer transmission device for the double-spiral drilling machine comprises a box body, wherein a first speed reduction device and a second speed reduction device are symmetrically arranged in the box body, the first speed reduction device comprises a first input shaft, a first output shaft and a first transmission shaft used for transmitting power, the second speed reduction device comprises a second input shaft, a second output shaft and a second transmission shaft which are symmetric with the first speed reduction device, a first transmission gear and a second transmission gear are respectively and symmetrically arranged on the first transmission shaft and the second transmission shaft, an idle wheel group is meshed between the first transmission gear and the second transmission gear, and the rotating speed of the first transmission shaft and the rotating speed of the second transmission shaft are enabled to be the same through the idle wheel group. When the power of one motor is insufficient, the sufficient power of another motor can be overlaid to the insufficient side through the idle wheel group, the damage to the motors caused by waste of resources or overload is avoided, the two motors are guaranteed to keep the optimum power distribution on the speed reducer transmission device, energy is saved, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of retarder, relates in particular to a kind of double helix rig retarder transmission device.
Background technique
The double helix rig is equipment commonly used in the seam mining, especially exploiting girdle uses especially extensive, the retarder transmission device of double helix rig comprise the cover reducing gear, this two covers reducing gear is respectively equipped with input end and output terminal, input end connects from different motor respectively, yet this two covers reducing gear is independently, when double helix rig one side meets hard rock, during the underpower of one of them motor, the rich power of another motor not enough side that can not be added to causes unbalance loading easily to damage motor.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of double helix rig retarder transmission device of can power helping each other is provided.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of double helix rig retarder transmission device, comprise casing, be arranged with the first speed reducer and the second speed reducer in the described casing, described the first speed reducer comprises the first input shaft, the first transmission shaft of the first output shaft and transferring power, described the second speed reducer comprises the second input shaft with the first speed reducer position symmetry, the second output shaft and second driving shaft, be arranged with respectively the first driving gear and the second driving gear on described the first transmission shaft and the second driving shaft, be engaged with the idle pulley group between described the first driving gear and the second driving gear.
As a kind of preferred version, described idle pulley group comprises two idle gears that mesh together, and described two idle gears rotate and are installed in the casing.
Owing to having adopted technique scheme, on described the first transmission shaft and second driving shaft, be arranged with respectively the first driving gear and the second driving gear, be engaged with the idle pulley group between described the first transmission driving gear and the second driving gear, when wherein a certain power of motor is not enough, the rich power of another motor can be by the idle pulley group not enough side that is added to, and make the rotating speed of the first transmission shaft and second driving shaft identical, guarantee that double helix bores the synchro-feed amount, avoid the wasting of resources or damage motor because of overload, guarantee that the power division of dual-motor on the retarder transmission device is best, save the energy, improved manufacturing efficiency.
