Abstract
An output shaft is a hollow shaft and passes through a gearbox. Holes for mounting also pass through the gearbox. The holes are located at the vertexes of a square or rectangle. And the output shaft, which is displaced (offset) relative to the square's (or rectangle's) center, is located on one diagonal of the square. This structure provides a variety of possibilities of assembling the gear device with a big motor, and the amount of projection of the faces of the gearbox from the output shaft can be kept as small as possible.
Claims10
A motor-equipped orthogonal gear device provided with a motor and a gearbox, said motor having a motor shaft, said gearbox being mounted to a mating machine, comprising,
- a hollow output shaft of said gearbox which passes through said gearbox, said hollow output shaft being arranged so that it is orthogonal to said motor shaft,
- holes for mounting which are arranged in four vertex positions of a square, said square being such that a position of said hollow output shaft is on a diagonal of said square and said position is, at the same time, displaced from a center of said square, and said holes for mounting also pass through said gearbox, and
- two mountable faces through which said output shaft and said holes for mounting pass, said gearbox being mounted to said mating machine through one of the mountable faces.
A motor-equipped orthogonal gear device provided with a motor and a gearbox, said motor having a motor shaft, said gearbox being mounted to a mating machine, comprising,
- a hollow output shaft of said gearbox, said hollow output shaft being arranged so that it is orthogonal to said motor shaft,
- a hypoid pinion which is directly formed on the motor shaft,
- a shaft, a center of which is displaced from the center of said motor shaft, and which is orthogonal to the motor shaft, and
- a hypoid gear which is mounted on said shaft and is meshed with said hypoid pinion.
