Problems solved by technology

[0008] 1. The main structure designed with the clutch drive is usually more complicated, and the manufacturing cost is high. There are many components in the clutch, which makes assembly and maintenance difficult. In addition, the clutch must be adjusted to manual mode before it can be operated manually
[0009] 2. The clutch drive is designed as a double worm and worm gear structure, which is driven by sliding friction. The motor transmission efficiency is poor, and the efficiency will be lower due to the increase of the transmission torque and the backlash wear will be large
[0011] 4. The differential gear planetary gear mechanism of U.S. Publication No. 4754949 and No. 6129337 patent case, because the planetary gear mechanism has a large backlash, it cannot be applied to the proportional valve driver, and the latter is due to eccentric rotation, so Prone to vibration and noise
[0012] 5. In the differential worm planetary gear valve driver of US Patent No. 4994001, the transmission efficiency of the motor driven single worm gear structure is poor

Abstract

The invention discloses a two-stage differential planetary gear driver, which comprises the first planetary gear group and the second planetary gear group. Wherein, the first planetary gear group comprises a fixing element, a drive element, the first driven element and the second driven element; the second planetary gear group comprises the first drive element, the second drive element and one driven element, while the first and second driven elements of said first planetary gear group are connected to the first and second drive elements of said second planetary gear group. The invention is a device with high flexible reducing rate without clutch while it can be handful operated and automatically operated synchronously. The output axle of said invention has the retaining function with high reducing transmission efficiency which can apply the 1 / 4 rotational or multi-rotational driver.

Description

technical field [0001] The invention relates to a two-stage differential planetary gear train driver, in particular to a two-stage differential planetary gear train driver with highly elastic reduction ratio and high transmission efficiency. Background technique [0002] When the power of the valve electric drive fails, it needs to rely on manual operation to switch for safety reasons. A clutch method such as US Publication No. 4474078 and No. 4546671 is used to optionally connect manual or motor operation, and Connect and drive the reduction gear for forward and reverse output. Among them, the traditional clutch of the US Patent No. 4474078 is engaged with the handwheel drive mechanism or the motor drive mechanism and is manually switched; the traditional manual electric valve driver of the US Patent No. 4546671 maintains the reliability of long-term use. And the driving gear device can only be transmitted in a low-speed mode with a high reduction ratio because it can resi...
