Title:
DOUBLE CROSS-CONNECTING GEAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/196751
Kind Code:
A1
Abstract:
The present invention relates to a method for coupling rotary shafts for power transmission by gear coupling. In the case of conventional gear couplings, a rotary shaft transmitting power always receives a biased torque, which may cause bearing abrasion and power loss. The purpose of the present invention is to transmit power from one rotary shaft to another rotary shaft with an unbiased torque. A disc-type hollow gear has gear teeth on both sides thereof, and a pair of insertion gears of a so-called bevel gear type are gear-coupled into a central hole of the disc-type hollow gear in such a manner that the insertion gears are symmetrical with each other with respect to an insertion hole. The disc-type hollow gear, i.e., a double-sided hole gear, secures the space of the insertion gears with a rotary mold and rotates by means of gear teeth corresponding to gear teeth of the insertion gears. The insertion gears to be inserted into the hole of the double-sided hole gear are divided into an inner coupling gear and an outer coupling gear and rotate while being engaged with the double-sided hole gear. The present invention enables the torque of one rotary shaft to be transmitted to another rotary shaft without undue friction, thereby minimizing abrasion of a machine without power loss.
