Problems solved by technology

[0004] 1. The size of parts increases, resulting in an increase in material costs
[0005] 2. A large gear shaper is required to process the inner ring gear, and the processing cost of the inner ring gear is high
[0006] 3. The ring gear is a thin-walled part, and increasing the size will further increase the processing difficulty of the part
[0007] 4. In the process of use, there will be phenomena such as tooth wear and tear, and the gear needs to be replaced as a whole, which is inconvenient to maintain and expensive to use

Embodiment 1

[0028] Embodiment 1: as figure 1 , figure 2 , image 3 As shown, a planetary transmission mechanism for a double-sided grinding / polishing machine includes a planetary gear 5 meshing with the ring gear 2, the planetary gear 5 is meshing with the sun gear 7, and the planetary gear 5 is arranged on the lower plate 6 , the inner side of the ring gear 2 is provided with a circle of ring gear pin teeth 3, and there is a tooth pitch between the two ring gear pin teeth 3, and the ring gear 2 is connected to the planetary wheel 5 through the ring gear pin teeth 3 engage. The gear of described planetary wheel 5 is arc tooth. The ring gear pin tooth 3 includes a ring gear pin shaft 3-1 and a ring gear pin sleeve 3-2, and a ring gear pin sleeve 3-2 is arranged outside the ring gear pin shaft 3-1, and a ring gear pin sleeve 3-2 is arranged outside the ring gear pin shaft 3-1. The top of the shaft 3-1 is provided with a ring gear pin sleeve limit screw 3-3. Ring gear pin shaft 3-1 is ...

Embodiment 2

[0029] Embodiment 2: the same as Embodiment 1, the difference is that a ring of sun gear pin teeth 4 is provided on the outer surface of the sun gear 7, and there is a pitch between the two sun gear pin teeth 4, and the sun gear 7 meshes with the planetary wheel 5 through the sun gear pin teeth 3. The sun gear pin teeth 4 all include a sun gear pin shaft and a sun gear pin sleeve, a sun gear pin sleeve is provided outside the sun gear pin shaft, and a sun gear pin sleeve limiter is provided on the top of the sun gear pin shaft. screw. The pin shaft of the sun gear is fixedly connected on the base of the sun gear. The pin shaft of the sun gear is arranged parallel to the outer surface of the sun gear.

[0030] The pin tooth 3 of the ring gear and the pin tooth 4 of the sun gear are both composed of two parts, the outside is the pin sleeve, and the inside is the pin shaft. The lower end of the pin shaft and the ring gear seat adopt an interference fit, and the pin shaft is tig...

Embodiment 3

[0031] Embodiment 3: Same as Embodiment 1, except that the distance from the stop screw 3-3 of the ring gear pin sleeve to the inner shoulder of the ring gear pin sleeve 3-2 is 1.5-2 mm.

Abstract

The invention relates to the field of a double-faced grinding / polishing machine, in particular to a planetary transmission structure of a double-faced grinding / polishing machine. The planetary transmission mechanism for the double-faced grinding / polishing machine comprises a planetary wheel (5) meshed with a gear ring (2), wherein the planetary wheel (5) is meshed with a sun wheel (7) and is arranged on a lower plate (6); a circle of gear ring pin teeth (3) are uniformly arranged on the inside surface of the gear ring (2); a tooth pitch is formed between two gear ring pin teeth (3); and the gear ring (2) is meshed with the planetary wheel (5) through the gear ring pin teeth (3). The invention has the advantages that because the pin tooth transmission is adopted, the cost of materials and the processing cost of an inner gear ring are reduced; the problem that the processing difficulty is increased because the size of the gear ring is increased is solved, and the problems of inconvenient maintenance and high using cost after the teeth are worn in the using process are solved; and simultaneously, because each pin tooth is in the shape of a circular arc and the meshing line is long, the contact rigidity of a part is improved, and the service life of the part is prolonged.

Description

Technical field: [0001] The invention relates to the field of double-side grinding / polishing machines, in particular to a planetary transmission structure of the double-side grinding / polishing machines. Background technique: [0002] In the traditional double-sided grinding / polishing machine, the ring gear and the sun gear meshing with the cruise ship are all made of ordinary involute gears, and the gears are in an integral form. The sun gear is an external gear, the ring gear is an internal gear, and the cruise wheel meshes with the two at the same time for planetary motion. [0003] In the traditional double-sided polishing and grinding equipment, the ring gear and the sun gear are integral gears. With the increase of equipment specifications, the size of the parts is also increasing. If the traditional structure is still used, the following problems will inevitably arise: [0004] 1. The size of parts increases, resulting in an increase in material costs. [0005] 2. A ...
