Problems solved by technology

If the power is too large, the battery power will be consumed too quickly, which will cause battery loss or power loss. At the same time, the motor current will increase, resulting in an increase in the conductive cross-section of the wire harness, a corresponding increase in heat generation and protection, and an increase in the production cost of the wire harness.
[0003] Ordinary transmission forms can only be driven by maintaining the output characteristics of ordinary DC motors. In most driving states, the efficiency of the motor is not high, and when designing and selecting the motor, the maximum value of the load needs to be used as the output of the drive mechanism. The ability to design, resulting in large motor selection power, the corresponding increase in motor cost, in mass production, resulting in a substantial increase in production costs

Embodiment 1

[0024] Such as figure 1 As shown, the worm-helical gear transmission mechanism in the form of a double booster mechanism that fits the load characteristics mainly includes a motor 1, a transmission screw 2, a mandrel 3, a turntable 4, a booster mechanism 1 5, a booster mechanism 2 6, and a transmission rod 7 , the buffer mechanism 8 and the external load 9, the motor 1 is arranged at the lower left part of the transmission mechanism, the motor 1 performs periodic forward and reverse rotation under the control of the control circuit, the transmission screw rod 2 is arranged at the inner lower part of the transmission mechanism, and the transmission screw rod 2 The left end of the motor is fixedly connected with the output end of the motor 1, the right end of the transmission screw 2 is movably connected with the inner wall of the transmission mechanism, the mandrel 3 is movably arranged inside the transmission mechanism above the transmission screw 2, and the turntable 4 is fixe...

Embodiment 2

[0027] Using the worm-helical gear transmission mechanism in the form of double booster mechanisms provided in Example 1 to study the specific influence of booster mechanism 1 and booster mechanism 2 on the transmission mechanism.

[0028] Firstly remove the booster mechanism 2, and measure the linearity of the boosting characteristics provided by the booster mechanism 1 when the turntable reciprocates, then remove the booster mechanism 1, install the booster mechanism 2, and measure the booster mechanism 2 when the turntable reciprocates. , the boost characteristics provided are sinusoidal, such as figure 2As shown, the first and second booster mechanisms are installed at the same time, and the force value, force point and booster direction of the first booster mechanism and the second booster mechanism are respectively adjusted. The resultant force of the booster mechanism is opposite to the direction of the load, and the characteristics are similar. Such as image 3 shown...

Abstract

The invention discloses a worm-helical gear transmission mechanism in the form of a double booster mechanism fitting load characteristics, including a motor, a transmission screw, a mandrel, a turntable, a booster mechanism 1, a booster mechanism 2, a transmission rod, a buffer mechanism and an external load. The motor is set at the lower left part of the transmission mechanism, the transmission screw is connected to the output end of the motor, and the turntable is fixedly sleeved on the mandrel. The turntable includes a driving disk and a passive disk. The gear, the transmission gear meshes with the transmission screw rod, and the connecting shaft is fixed on the passive disk. The first two and the spring rod, the transmission rod are connected with the external load, and the buffer mechanism is arranged in the middle of the transmission rod.

Description

technical field [0001] The invention belongs to the technical field of motor transmission, and in particular relates to a worm-helical gear transmission mechanism in the form of a double booster mechanism fitting load characteristics. Background technique [0002] In automobile production, the conventional on-board power supply is mainly batteries and generators. Before the vehicle is started, the only power supply is the battery. The on-board electrical equipment works when the vehicle is not started. effective control and reduction. If the power is too large, the battery power will be consumed too quickly, which will cause battery loss or power loss. At the same time, the motor current will increase, resulting in an increase in the conductive cross section of the wire harness, a corresponding improvement in heat generation and protection, and an increase in the production cost of the wire harness. [0003] Ordinary transmission forms can only be driven by maintaining the ...
