Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of turntable driving for a phonograph player, in particular to a double idler wheel driving structure for a turntable for a vinyl phonograph player. Background Art
[0002] Up to now, there are several common forms of turntable drive for vinyl record players: motor belt and motor direct drive, that is, the turntable of vinyl record players is driven by the transmission method of motor belt, idler wheel and idler wheel, among which only one idler wheel is used. The idler wheel plays the role of transmitting the rotational force of the motor to the turntable. It is a combination of rubber or metal and rubber. The motor shaft rubs it, and it rubs the turntable. Early turntables were relatively light in weight, so there was no big problem with using one idler wheel. However, in recent years, turntables have become heavier and heavier, and it is not conducive to using one idler wheel to start the turntable and maintain stable operation. Therefore, it is necessary to increase the number of idlers to two, forming a two-dimensional control mode, which is similar to controlling the steering wheel while driving a car. It is also illegal to use one hand if it is unstable, and both hands must be used.
[0003] For this reason, we designed a double idler drive structure for the turntable. Utility Model Content
[0004] The utility model aims to solve the problem that turntables have become increasingly heavy in recent years, and it is disadvantageous to still use one idler wheel to start and maintain stable operation of the turntable, and proposes a double idler wheel driving structure for a vinyl record player turntable.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] The double idler wheel driving structure of a vinyl record player turntable comprises a vinyl record player turntable and a motor. The motor drives two intermediate wheels, and the intermediate wheels are in contact with the vinyl record player turntable through the idler wheels.
[0007] Preferably, the output end of the motor is synchronously driven with the intermediate wheel through a belt.
[0008] Preferably, the output end of the motor is fixed with pulleys corresponding to the number of intermediate wheels, and the pulleys are driven by belts and intermediate wheels.
[0009] Preferably, the two idler wheels are in contact with the outer side wall of the turntable and are symmetrically arranged on both sides of the turntable.
[0010] Preferably, the two idler wheels are located in the same straight line as the rotation axis of the turntable of the vinyl record player.
[0011] Preferably, the two idler wheels form an angle of ° with the rotation axis of the turntable of the vinyl record player.
[0012] Preferably, the two idler wheels are in contact with the inner side wall of the turntable and are symmetrically arranged on both sides of the turntable. The two idler wheels and the rotation axis of the turntable are located in the same straight line.
[0013] The beneficial effects of the utility model are:
[0014] 1. The utility model adopts two idler wheels to connect with the turntable of the vinyl record player. For the double idler wheel driving structure, the turntable of the vinyl record player is easy and stable during starting and running, and the dynamic balance is better than that of the single idler wheel structure, thereby reducing the shaking and distortion of the record player.
[0015] 2. The utility model adopts a setting in which two idler wheels and the rotating shaft of the vinyl record player turntable form an angle of 120° with each other. The adjustment of this angle can be selected and determined according to the overall structural layout of the record player to ensure the smooth operation of the vinyl record player turntable.

[0022] Embodiment 1
[0023] Reference Figure 1-Figure 5 The double idler wheel driving structure of the vinyl record player includes a vinyl record player turntable 1 and a motor 3. The motor 3 drives two intermediate wheels 4, and the intermediate wheels 4 are in contact with the vinyl record player turntable 1 through the idler wheel 2. This improved driving method Figure 2 and the traditional single idler belt drive Figure 3 In contrast, increasing the number of idler wheels 2 to two makes the control mode two-dimensional.
[0024] With the dual idler drive structure, the turntable 1 is easy and stable both during startup and operation, and the dynamic balance is better than that of the single idler structure, thereby reducing the jitter and distortion of the turntable.
[0025] The output end of the motor 3 is synchronously driven with the intermediate wheel 4 through the belt 5. The output end of the motor 3 is fixed with pulleys corresponding to the number of the intermediate wheels 4, and the pulleys are transmitted to the intermediate wheels 4 through the belt 5. In this way, the rotation of the motor 3 is transmitted through the belt 5 to make the two intermediate wheels 4 rotate synchronously. Since the two idler wheels 2 are still powered by one motor 3, the speed of the turntable 1 of the vinyl record player can be adjusted arbitrarily like a single idler wheel structure.
[0026] Reference Figure 3 In this state, the two idler wheels 2 are in contact with the outer side wall of the turntable 1 and are symmetrically arranged on both sides of the turntable 1, so that it is convenient for the motor 3 to drive the two idler wheels 2 on the symmetrical outer side walls of the turntable 1. When the two idler wheels 2 beside the turntable 1 contact the intermediate wheel 4 and the turntable 1 at the same time, they work together to frictionally drive the turntable 1 to move in one direction, and the clutch action of the idler wheels 2 can be controlled by a mechanical device.
[0027] The two idler wheels 2 are located in the same straight line as the rotation axis of the turntable 1, which ensures the smooth rotation of the turntable 1 and reduces the shaking distortion.
[0028] The working principle of the utility model is as follows:
[0029] By turning on the motor 3, the output end of the motor 3 drives the two intermediate wheels 4 to rotate. The intermediate wheels 4 contact the turntable 1 through the idler wheel 2 and drive the turntable 1 to rotate. For the double idler wheel drive structure, the turntable 1 is easy and stable during startup and operation, and the dynamic balance is better than the single idler wheel structure, thereby reducing the jitter and distortion of the turntable.
[0030] Embodiment 2
[0031] Reference Figure 4 In this state, the two idler wheels 2 and the rotation axis of the turntable 1 of the vinyl record player form an angle of 120° with each other, and the adjustment of this angle can be selected and determined according to the overall structural layout of the record player.
[0032] Embodiment 3
[0033] Reference Figure 5 In the state, the two idler wheels 2 are in contact with the inner wall of the vinyl record player turntable 1 and are symmetrically arranged on both sides of the vinyl record player turntable 1. The two idler wheels 2 and the rotation axis of the vinyl record player turntable 1 are located in the same straight line. Figure 3 Compared with the previous state, the turntable 1 of the vinyl record player rotates in the opposite direction at this time.
