gear box and the revolution ratio

In the absence of a power source, it is necessary to create a device that is powered by potential energy, including springs and gravity. Such as the white motion tracking sunlight mechanism of solar receiver, it needs a small volume, the lightest weight and accurate automatic control device. We make a kind of clock control transmission device with alarm clock and unconventional gear transmission box, which is used to control the operation of solar cooker surface. It is called time control device for short. It is used in flat solar cooker. It is composed of active and passive gear belts, solar receivers and alarm clocks. The SOURCE OF THE MOMENT ON THE FOCAL SURFACE IS TO ADD a COUNTERweight on both sides of THE focal surface that can move along the focal surface to change the magnitude of the rotational moment in the west direction, which is used as the rotational force for solar migration. Through the time controller, with an alarm clock to control the rotation speed, the belt acting on the belt pulley and the direction of rotation of the spring shaft is a tooth surface force analysis and tooth surface Angle to determine the design of the gear is the application of the principle of heavy sliding on the inclined plane. When a tooth of a driving gear meshes with a tooth of a passive gear, it is regarded as a heavy object sliding down a bevel, forcing the tooth to move in a horizontal direction because the mouth of the tooth slides down vertically. The normal reaction force and the maximum static erasure force can be replaced by the fully constrained reaction force, which is caused internally by the resultant force.

On the contrary, the alarm clock can not control the function, should change the direction of the belt. The passive gear consists of two pieces with the same number of teeth and the teeth with different circumference, which are mounted together, that is, the tooth peak of one piece is aligned with the tooth valley of the other piece and fixed on the shaft. The driving gear can use three standard cylindrical gears with the same parameters as the passive gear. The corner of the alarm clock is in the gearbox. The size of the gear can be determined according to the profile of the gear box and the ratio of revolutions, and the modulus can be determined according to the size of the load. The thickness of each piece of gear should be less than the distance between the teeth to avoid clamping. We adopt the standard cylindrical gear with blade teeth and modulus. In the reform method of driving gear, one tooth of the original gear is milled out every other tooth to make a tooth, and then one tooth surface Angle is milled on each tooth of the three pieces of gear, that is, the processing of the gear is completed. When the moment magnification is determined, the tooth surface Angle can be calculated according to Equation or Equation. The number of teeth of the driving gear is set as the number of teeth of the passive gear is the number of spoons. The number of teeth of the upper gear is doubled due to the fact that the moving gear turns a tooth every two teeth of the passive gear, and the driving gear removes a tooth every other tooth.
