Abstract

PURPOSE:To improve efficiency, by braking a shaft having an increased speed and a low torque by means of a frictional braking material, and controlling the shaft of a surface driving gear, etc. by an independent power. CONSTITUTION:A cross-shaft type synclinal gear mechanism is formed by a surface driving gear 1, a synclinal gear 2 and a surface driven gear 4 to drive a motor M1 directly connected to an input shaft S1. Although same directional torque of an inclined shaft 3 and an output shaft S4 of the synclinal gear mechanism is increased in proportion to a rotational speed, output torque of the synclinal gear mechanism with a large reduction ratio as in the preferred embodiment is reduced by an amount of efficiency. One shaft S3 of the surface driving gear 1 of the cross-shaft type synclinal gear mechanism for the motor M1 is connected through helical grear train 6, 7 and 8 to the shaft S5 of a surface driven gear 14 of an independently formed speed-increasable synclinal gear mechanism. The braking plate 9 of an electromagnetic brake MB is fixed to the inclined shaft S6 of a conical rocking member 13.

Description

[Detailed description of the invention] The orthogonal shaft type internal medicine oscillation gear mechanism (Patent application 3, March 12, 1980, application number, 1982-) is an internal medicine oscillation gear mechanism (
7 on the outer periphery of the cloth oscillating gear
A conical roller that fits into the groove is driven by an input diagonal shaft provided in the radial direction of the output shaft, and by rotating the diagonal shaft of the non-clutch gear in the same direction, the pair of face gears are rotated in opposite directions. It is a shift plane gear mechanism that swings in the direction. Therefore, the input shaft can be arranged in one or more stages in the radial direction of the output shaft, and the diagonal shaft of the non-cross gear that rotates at the same time as the input shaft can be used as a drive shaft.
Although the three rotational components of the driven surface gear are easy to use as output or control elements, it is difficult to produce a driven surface gear with a small rotation ratio. In particular, orthogonal shaft type non-cruise gears are easier to design for strength as the rotation ratio is relatively thicker near the center between the rotating plane gears with their oscillation centers facing each other, but the rotation ratio can be increased due to the differential component. The disadvantage is that the locking property increases rapidly, the efficiency deteriorates, and reverse transmission (speed increase) becomes impossible. Non-kuru gear has a large rotation ratio in one mechanism (up to the square of the maximum number of reference plane gear teeth)
However, since the driving face gear directly supports the load torque, a rotary converter that needs to control it must be equipped with a low-speed, large-torque rotation/braking device.

The present invention connects the drive surface tooth pawl to a gear mechanism with low locking property using a crank or a gear train, brakes the shaft that increases speed and reduces torque with a friction brake, and separates the drive surface gear shaft and the speed increase shaft. This invention relates to an orthogonal shaft type internal medicine head oscillation gear mechanism with a speed-increasing gear that can be controlled by the power of .

Of course, control of this type of revolution gear converter is a conventional method, but the Nkuru Gya has many characteristics and effects that are different from other gear mechanisms. (Reference: Nishinkle Gear Technical Design Materials, edited by JEC) The purpose of the present invention is to make it suitable for use before power, in applications with large rotation ratios such as valves and opening/closing doors, which can be driven by a separate power source or driven from the load side. The mechanism is different from the conventional Shinkle Bomber.

I will explain the drawings. FIG. 1 is a sectional view of this mechanism.

41d When viewed from the shaft end, the torque increases in proportion to the rotational speed, but in the case of a large reduction ratio as in this embodiment, the output torque of the sinkle gear decreases by the amount of efficiency. In this case, a normally designed sinkle gear reducer will have a complete gear lock, from the output shaft (s4) to the oblique shaft (s2) and input oblique shaft (

In the example, the number of teeth of the fixed surface gear α = 35, the number of teeth of the cloth vibration gear (B) N2 = N3 = 37, and the number of teeth of the driven surface gear α =

can be driven in reverse. Therefore, a friction plate type electromagnetic brake can be used since a shaft (S6) braking brake (MB) with a capacity of about V5o of tri output torque is sufficient. Furthermore, there is a control motor (MZ) on the shaft (S6).
When 1800 rpm is installed, the output shaft (S4) when MIM2 is applied is 1 1 36 900 1800 X --+ 1800 X-plane X so X
= 2 + 3a04ki38rpm00 Similarly, the output can be changed to 4 speeds by differentially setting M and N2 or operating independently. This mechanism allows orthogonal shaft type sinkle gears to be linked with a separately installed speed increasing gear mechanism using a gear train or a rotating arm. The output shaft (S4) can be driven by separate power.

Moreover, since the clutch function of the main power is obtained by low-torque braking of the speed increasing section, inching operation of the output shaft, fixed position, and constant pressure stopping operation are possible.

For applications where the maximum rotation angle is less than 900 degrees, such as before power or for opening/closing doors, a rotating arm αO→ as shown in FIG. 2 can be connected via a connecting culm αNO instead of a gear train. This system allows both sides of the 9-rotating body (different from the crank) to be driven and driven evenly, so there is no dead center, the balance of forces is maintained, and the load on the bearings is reduced. Mechanically, it is simple and strong with no play.

When applying this embodiment as a marine power steering gear, the output shaft (
S4) is directly connected to the front frame (87) VC, or a rotating arm and a connecting frame as shown in Fig. 2 are used. When sailing, the rudder has the ability to restore straightness due to water pressure, but when the driving and braking sources are cut off, the rudder θ→ may meander due to waves and currents. In this case, as shown in FIG. 3, it is also possible to install a device that forcibly restores the front frame (s7) and shaft (s4) to the straight-ahead position using a damper α using a coil spring.

/NkuruGya can obtain a large rotation ratio with a single mechanism, so even if a high-speed electric motor is used, low speed and high torque can be achieved, and accurate steering can be achieved through temporal ON/OFF operation and pulse control. Further, fine adjustment and inching of the rudder can be done quickly by turning on and off the electromagnetic brake (MB), and steering is easy because it is held when the brake is on and automatically moves straight when the brake is off. - If the power system is malfunctioning, the shaft (S2
) or (S3) can also be used. Remote control requires only two or three signal wires and a reversible switch, and a steering angle indicator can also be easily installed if necessary.

In particular, the single gear type power steering gear is small, powerful, and has no play, so it is the best at resisting shock loads.

Similarly, this mechanism can also be applied to drive opening/closing doors.

Since the maximum rotation angle of the openable/closable door I'i is 90 degrees or less, the swing arm can be used. It can be powered open, fluid controlled, spring return self-closing, or can be opened and closed manually. Due to this feature, which is mechanically non-lockable and can be manually operated while stopped, this mechanism is expected to be highly effective in many applications such as Nyanotar hoisting machines and opening/closing drives for various valves.
