Description

Technical Field

[0001] This utility model relates to the field of multi-planetary gear detection technology, specifically to a steady-state analysis device for a multi-planetary gear transmission system. Background Technology

[0002] Multi-planetary gear transmission systems are mechanical transmission devices that transmit power through multiple planetary gears or planetary gear sets. They feature high power density, compact structure, and flexible transmission characteristics, and are widely used in industries such as industry, automobiles, and aerospace.

[0003] It consists of a sun gear (central driving gear), multiple planet gears (revolving around the sun gear and rotating on their own axes), a planet carrier (supporting the planet gears and outputting power), and an internal ring gear (fixed or participating in rotation). By increasing the number of planet gears or cascading planet gear sets, the load distribution and transmission ratio can be optimized.

[0004] Currently, in the actual manufacturing process of multi-planetary gearboxes, which are speed-increasing gearboxes, the transmission from the gear ring to the planetary gears is transmitted to the power shaft. However, such gearboxes are prone to generating noise and temperature during operation, requiring monitoring of noise and temperature during operation and steady-state noise and temperature analysis of the multi-planetary gear transmission system. Currently, there is no comprehensive steady-state analysis device capable of monitoring planetary gearboxes. Therefore, a steady-state analysis device for multi-planetary gear transmission systems is needed. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a steady-state analysis device for a multi-planetary gear transmission system, in order to solve the current technical problem that, in the actual manufacturing process of multi-planetary gearboxes, since they are speed-increasing gearboxes, the transmission to the power shaft is achieved through the rotation of the gear ring and the planetary gears. However, such gearboxes are prone to generating noise and temperature during operation, requiring monitoring of noise and temperature during the operation of the multi-planetary gear transmission system and conducting steady-state noise and temperature analysis. Currently, there is no perfect steady-state analysis device capable of monitoring planetary gearboxes.

[0006] To achieve the above objectives, this utility model employs the following technical solution:

[0007] A steady-state analysis device for a multi-planetary gear transmission system includes a chassis base. Support feet are fixed to the bottom of the chassis base and grounded therein. Two short and two long protective plates are fixed to the top of the chassis base, forming an analysis chassis. A planetary gearbox is placed on top of the chassis base. Several fixed temperature sensors are fixedly installed on the inner wall of the long protective plate of the chassis base. A movable temperature sensor is installed on the inner wall of one of the short protective plates of the chassis base, and a movable vibration sensor is installed on the inner wall of the other short protective plate of the chassis base.

[0008] As a preferred technical solution of this utility model, the top of the analyzer chassis is provided with a first top cover plate and a second top cover plate, which are slidably connected at the top of the analyzer chassis and slide back and forth alternately at the top of the analyzer chassis.

[0009] As a preferred technical solution of this utility model, a gearbox bracket is fixedly installed on the top of the chassis base, and a planetary gearbox is fixedly installed on the top of the gearbox bracket. The planetary gearbox has a sun gear, planet gears, a drive shaft, and a gear ring, with the gear ring disposed on the outer ring of the planetary gearbox.

[0010] As a preferred embodiment of this utility model, a servo motor is fixedly installed at the top of the chassis base, the servo motor has an output shaft extending outward, and a movable gear is fixedly installed on the surface of the output shaft of the servo motor, the movable gear meshing with a gear ring.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention utilizes a first and a second top cover plate that slide alternately at the top of the analyzer housing, facilitating the opening and closing of the analyzer housing. By placing the planetary gearbox inside a closed analyzer housing, it is beneficial to more accurately detect the low-decibel noise during the operation of the planetary gearbox.
