Description

  The present invention relates to a gear box device, and in particular, when the rotating levers of a plurality of gear box portions are simultaneously rotated by a motor, and the rotating levers are manually rotated by a torque diode connected to the motor. The present invention relates to a novel improvement for blocking torque transmission to the motor side and blocking back drive.

  In the case of a gear box device using a plurality of rotating levers of this type that has been used in the past, because the patent application was not filed only by in-house production, the name of the patent publication is not listed here, In general, rotation from each lever side is not transmitted to the motor side via a large clutch provided outside the housing.

Since the conventional gearbox device using a plurality of rotating levers is configured as described above, the following problems exist.
In other words, a large clutch mechanism for turning on and off the transmission between the motor and each rotation lever was provided outside the housing, so the overall shape of the device itself was enlarged and installed in a narrow space such as a flying object. It was extremely difficult to do.

  A gear box device according to the present invention includes a plurality of gear box portions provided along a longitudinal direction of a housing, a common drive shaft provided rotatably in each gear box portion, and an upper portion of the housing. An upper drive shaft driven by a provided motor, a connection gear provided on each individual drive shaft of each gear box portion to link the upper drive shaft and the common drive shaft, and below each gear box portion A rotation lever provided rotatably, a lever gear provided in each rotation lever and interlocking with the connection gear, and a torque diode provided in the motor, wherein the upper drive shaft is provided by the motor. By rotating the rotary levers via the connecting gear and the lever gear, and the turning power when the rotary levers are rotated is the torque diode. It is blocked, wherein the the motor side is constituted not transmitted.

Since the gear box device according to the present invention is configured as described above, the following effects can be obtained.
That is, it is driven by a plurality of gear box portions provided along the longitudinal direction of the housing, a common drive shaft that is rotatably provided in each gear box portion, and a motor provided on the upper portion of the housing. An upper drive shaft, a coupling gear provided on each individual drive shaft of each gear box portion for interlocking the upper drive shaft and the common drive shaft, and a rotatable portion below each gear box portion. A rotation lever, a lever gear provided in each rotation lever and interlocking with the connection gear, and a torque diode provided in the motor, and by rotating the upper drive shaft by the motor, The rotating power when the rotating levers are rotated via the connecting gear and the lever gear, and the rotating levers are rotated, is interrupted by the torque diode, and the motor Since the is a configuration in which the not transmitted, it is possible to built a torque diode is a one-way clutch in the housing, it is possible to obtain a compact gear box unit.
Further, when each turning lever is turned manually or the like, reverse torque transmission to the motor side is blocked by the torque diode, and the turning lever can be turned.

  In the present invention, when the rotating levers of the plurality of gear box portions are simultaneously rotated by the motor and the rotating levers are manually rotated, torque transmission to the motor side is performed by a torque diode connected to the motor. An object of the present invention is to provide a gear box device that shuts off the back drive.

A preferred embodiment of a gear box device according to the present invention will be described below with reference to the drawings.
In FIG. 1 and FIG. 2, a reference numeral 1 indicates a casing having an open top frame shape as a whole. A torque diode 2 </ b> A that is a well-known one-way clutch is provided on the top of the casing 1 by a motor 2. An upper drive shaft 3 that is rotationally driven via the first bearings 4 and 5 is disposed. As shown in FIG. 3, the torque diode 2 </ b> A has a known structure and is configured such that the output shaft 2 </ b> B from the motor 2 becomes a one-way clutch depending on the rotation direction.

The casing 1 is divided into four chambers 7, 8, 9, and 10 by a plurality of walls 6, and the upper drive shaft 3 is disposed in a state of straddling the chambers 7, 8, 9, and 10. ing.
In the lower position of the upper drive shaft 3 in the casing 1, the chambers 7, 8, 9 are interposed via a pair of second bearings 11, 12 provided in the chambers 7-10 of the casing 1. 10, individual drive shafts 13 are rotatably provided.

  In each of the chambers 7, 8, 9, and 10, a connection gear 14 provided on each individual drive shaft 13 is provided, and below each connection gear 14, each wall 6 is connected via a shaft 17. A rotation lever 16 having a lever gear 15 that is pivotally supported is rotatably provided.

  The upper drive shaft 3 meshes with the connection gear 14 via a tooth portion 3 a, and the connection gear 14 meshes with the lever gear 15, whereby the torque of the motor 2 is transmitted via the connection gear 14. The rotation lever 16 is rotated by being transmitted to the rotation levers 16.

Further, when each of the rotating levers 16 is manually rotated while the motor 2 is off, the one-way clutch of the torque diode 2A causes the motor 2 to reverse from the connecting gear 14 and the upper drive shaft 3 side. Torque transmission is blocked.
A gear box portion 20 is formed by the connecting gear 14 and the lever gear 15 provided in the respective chambers 7, 8, 9, and 10 described above.

It is a disassembled perspective view which shows the gearbox apparatus by this invention. It is sectional drawing of FIG. It is a front view of the principal part which shows the motor and torque diode of FIG.
