Description

Technical Field

[0001] The utility model relates to the technical field of planetary gear installation, in particular to a planetary frame which is convenient for fast and fixed installation of planetary gears. Background Art

[0002] Planetary gears refer to gear systems that can rotate around their own rotation axes like fixed-axis gears, and their rotation axes can also rotate around the axes of other gears along with the planet carrier. Rotation around one's own axis is called "autorotation", and rotation around the axes of other gears is called "revolution", just like the planets in the solar system, hence the name. The planet carrier is one of the main components of the planetary gear transmission device, and the planetary gear shaft or bearing is installed on the planet carrier. When the planetary gear is used as a basic component, it is the part that bears the largest external torque in the mechanism. The current planet carrier is not very convenient to fix and install when installing the planetary gear. When installing the planetary gear, the teeth of multiple planetary gears need to correspond to the inner teeth of the gear ring at the same time, so multiple planetary gears need to be rotated and adjusted during installation, which is cumbersome to operate. In addition, the weight of the planetary gear is large, and it is already quite laborious to lift the planetary gear. It requires the assistance of multiple people to complete the installation, which reduces work efficiency.

[0003] And in the document with the publication number CN215720751U, a planetary carrier for fast and fixed installation of planetary gears is mentioned. The planetary carrier places the planetary carrier body on the top of the gear ring, so that the teeth of one of the planetary gear bodies contact the spring piece, presses the planetary carrier body downward, drives the planetary gear body to descend, and the spring piece limits the planetary gear body, drives the planetary gear body to deflect, and when the planetary gear body descends, the teeth fit with the inside of the V-shaped plate. When the planetary gear body is engaged with the V-shaped plate, the planetary gear body drives the sun gear to rotate, and the sun gear drives the remaining planetary gear bodies to rotate. Because the V-shaped plate corresponds to the teeth of the gear ring, the planetary gear body corresponds to the teeth of the gear ring, which is conducive to the installation of the planetary gear body without teeth alignment, and improves the installation efficiency. However, there are still certain defects that need to be optimized. The specific defects are as follows: the spring piece in the structure cannot be replaced, and it may cause wear and reduce the positioning accuracy after multiple disassembly and installation in the later maintenance. At the same time, the planetary gear system will generate friction heat during operation. Without good lubrication and heat dissipation measures, the performance and life of the system will be affected.

[0004] Therefore, it is particularly important to design a planet carrier that is convenient for quickly fixing and installing planetary gears to change the above technical defects and improve overall practicality. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] In the utility model, a planetary carrier is provided which is convenient for fast fixing and installing planetary gears, and a structure of heat dissipation groove, exhaust fan, heat-conducting fin, heat-conducting gel, heat-conducting hole and oil-accumulating gasket is used.

At the same time, the planetary gear system will generate friction heat when working, and without good lubrication and heat dissipation measures, the performance and life of the system will be affected.

[0024] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0025] A planetary frame for fast fixing and installing planetary gears, comprising a fixing seat 1, a bottom plate 2 is provided at the top of the fixing seat 1, a plurality of heat dissipation grooves 101 are provided on the inner side walls of the fixing seat 1, an exhaust fan 102 is provided on one side of the heat dissipation groove 101, a heat conducting fin 201 is provided through the top of the bottom plate 2, a heat conducting gel 202 is provided at one end of the heat conducting fin 201, a plurality of heat conducting holes 203 are provided on the bottom plate 2, a spring damping shock absorber 103 is symmetrically provided inside the fixing seat 1, a gear ring 3 is provided at the top of the bottom plate 2, a V-shaped plate 301 is provided on the top of the V-shaped plate 301, and a mounting plate 303 is provided on the top of the V-shaped plate 301 02, a spring sheet 303 is provided inside the mounting plate 302, a slot 304 is provided inside the spring sheet 303, an oil accumulation gasket 305 is provided inside the slot 304, a slot 306 is provided inside the mounting plate 302, a plurality of mounting holes 307 are provided on the mounting plate 302, a sun gear 4 is provided inside the gear ring 3, the sun gear 4 is connected to the planetary gear body 402, the planetary gear body 402 is connected to the planetary carrier body 403, a cover plate 5 is provided on the top of the gear ring 3, and the planetary carrier body 403 is placed on the top of the gear ring 3 so that the teeth of one of the planetary gear bodies 402 are aligned with the top of the V-shaped plate 301. The spring piece 303 contacts and presses down the planet carrier body 403, so that the teeth of the planetary gear fit with the inside of the V-shaped plate 301. At this time, the spring piece 303 limits and deflects the planetary gear. At the same time, due to the squeezing of the planetary gear, the oil stored in the oil gasket 305 will be released to the teeth, and then the other gears will be lubricated by the rotation of the gear. At the same time, the spring piece 303 can be replaced by bolts. When the planetary gear is engaged with the V-shaped plate 301, the planetary gear drives the sun gear 4 to rotate, and the sun gear 4 then drives other planetary gears to rotate. Because the V-shaped plate 301 corresponds to the teeth of the ring gear 3, the planetary gear The teeth of the gear and the gear ring 3 also correspond automatically, simplifying the gear alignment steps. When the planetary carrier body 402 descends, the spring damping shock absorber 103 at the bottom produces a damping effect, providing support for the planetary carrier body 403, which helps to stably fix the planetary carrier body 403. After the planetary gear and the gear ring 3 are installed, the cover plate 5 is placed on the top of the gear ring 3 and fixed with bolts to complete the installation of the entire planetary carrier. At the same time, the heat conductive gel 202 and the heat conductive fins 201 located inside are used for heat dissipation when the gear is working, and are directional heat conduction to the inside of the fixing seat 1, and then the hot air is discharged through the exhaust fan 102;

[0026] The cross-sectional shape of the heat dissipation slot 101 is trapezoidal, and the opening width of the heat dissipation slot 101 is greater than its bottom width, which is convenient for improving the heat dissipation efficiency. The material of the heat-conducting fin 201 is copper or aluminum with good thermal conductivity, and the shape of the heat-conducting fin 201 is wavy to increase the heat dissipation area. The speed of the exhaust fan 102 is adjustable to facilitate heat dissipation. The spring 303 is made of elastic material and its shape is arc-shaped, which is convenient for better fitting the side of the planetary gear body 402. The material of the oil accumulation gasket 305 is kapok fiber, which is used to absorb and store lubricating oil to reduce friction and wear. The mounting plate 302 and the V-shaped plate 301 and the spring 303 are fixed in position by bolts, and the V-shaped plate 301 and the mounting plate 302 can be clamped. The cover plate 5 and the ring gear 3 are connected by bolts to facilitate disassembly, maintenance and replacement.

[0027] The working process of the utility model is as follows: when using the planetary carrier that is convenient for fast fixing and installing planetary gears, firstly place the planetary carrier body 403 on the top of the gear ring 3, so that the teeth of one of the planetary gear bodies 402 are in contact with the spring piece 303 on the top of the V-shaped plate 301, and press the planetary carrier body 403 downward to make the teeth of the planetary gear fit with the inside of the V-shaped plate 301. At this time, the spring piece 303 limits and deflects the planetary gear. At the same time, due to the squeezing of the planetary gear, the oil stored in the oil gasket 305 will be released onto the teeth, and then other gears will be lubricated by the rotation of the gear. At the same time, the spring piece 303 can be replaced by bolts. When the planetary gear is engaged with the V-shaped plate 301, the planetary gear drives the sun gear 4 to rotate. The male gear 4 then drives the other planetary gears to rotate. Since the V-shaped plate 301 corresponds to the teeth of the ring gear 3, the teeth of the planetary gear and the ring gear 3 also automatically correspond, which simplifies the tooth alignment steps. When the planetary carrier body 402 descends, the spring damping shock absorber 103 at the bottom produces a damping effect, providing support for the planetary carrier body 403, which helps to stably fix the planetary carrier body 403. When the planetary gears and the ring gear 3 are installed, the cover plate 5 is placed on the top of the ring gear 3 and fixed with bolts to complete the installation of the entire planetary carrier. At the same time, the thermal conductive gel 202 and the thermal conductive fins 201 located inside are used for heat dissipation when the gears are working. The heat is directed to the inside of the fixing seat 1, and then the hot air is discharged through the exhaust fan 102.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
