Title:
ELECTRIC BRAKE
Document Type and Number:
Japanese Patent JP2017061203
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve the size reduction and a degree of freedom of the layout of an electric brake having a reduction mechanism for decelerating the rotation of an electric motor.SOLUTION: As a reduction mechanism which decelerates the rotation of an electric motor 1 and outputs it, a roller reduction gear 2 that can provide a reduction ratio which is higher than that of a planetary gear mechanism and has a large torque capacity is used. The roller reduction gear 2 is arranged coaxially with the electric motor 1 and connected to the electric motor 1 not via a reduction gear, thus enabling reduction of the size of the whole brake compared to conventional ones while securing a required reduction ratio and a torque capacity and improvement in a degree of freedom of a layout.SELECTED DRAWING: Figure 1
