Problems solved by technology

[0006] The invention solves the defects that the existing rollers reduce the friction resistance of the rollers by adding industrial lubricating oil, reduce the wear of the rollers, easily cause the lubricating oil to overflow and contaminate the rollers and surrounding objects, and provide a free To lubricate the chain rollers, set a copper sleeve with lubricating graphite on the inner wall of the rollers, and immerse food-grade oil into the graphite under pressure, which can ensure sufficient lubrication between the rollers and the sleeves and reduce The wear of the rollers improves the comfort of the rollers, and at the same time prevents the lubricating oil from seeping out and contaminating the rollers and surrounding items
[0007] The present invention also solves the defects that the lubricating oil is not easy to retain after the roller is worn out and the lubricating effect decreases, and provides a lubrication-free chain roller. The inner wall of the roller is provided with a copper sleeve, and graphite is arranged inside the copper sleeve. Graphite has a lubricating part that matches the inner surface of the copper sleeve. Under pressure, food-grade oil is immersed in the graphite, and there is no need to add lubricating oil to the rollers. Even if the rollers are worn, there is enough graphite to play a role in lubrication and strengthen The effect of lubrication

Embodiment 1

[0026] Embodiment 1: a kind of lubrication-free chain roller (see figure 1 figure 2 image 3 ), including a steel outer sleeve 1 and a copper inner sleeve 4 embedded in the inner wall of the outer sleeve, the copper inner sleeve and the steel outer sleeve are interference fit, the copper inner sleeve has an inner hole, and the inner hole matches the chain sleeve .

[0027] The copper inner sleeve includes a plurality of side-by-side rings 8 and copper walls 9 connecting adjacent rings. The inner walls of the copper walls are flush with the inner walls of the rings. In this embodiment, there are 7 rings, and the rings are Circular, the inside of the ring is provided with an open slot 10, the notch of the open slot faces the center of the ring, and a connecting arm 7 is connected between adjacent rings, the connecting arm is connected with the appearance of the copper wall, and the height of the connecting arm is It is smaller than the radial thickness of the rings, the conn...

Embodiment 2

[0031] Embodiment 2: A lubrication-free chain roller. The difference from Embodiment 1 is that the inner wall of the steel jacket is provided with a ring groove 12, and the position of the ring groove corresponds to the position of the copper wall, that is to say, it communicates with the ring cavity , oil-absorbing cotton 13 is embedded in the ring groove (see Figure 4 ), the ring groove is rectangular, and the thickness of the oil-absorbing cotton is smaller than the depth of the ring groove. Refer to Example 1 for all the other structures.

[0032] After the roller is immersed in food-grade oil under pressure, the oil-absorbing cotton will absorb the infiltrated food-grade oil for storage, and the oil-absorbing cotton is in contact with the graphite block in the ring cavity.

Embodiment 3

[0033] Example 3: A lubrication-free chain roller, the difference from Example 1 is that the copper inner sleeve is an assembled structure, the assembled position is at the copper wall, the ring is a complete structure, and the assembly adopts the male and female mating structure. see Figure 5 , the copper inner sleeve is divided into 5 intermediate assemblies 17 and 2 end assemblies 18, each intermediate assembly has a complete ring 8 and 1 / 2 high copper walls 9 on both sides of the ring, and the end assemblies It has a complete ring 8 and a 1 / 2 high copper wall 9 on one side of the ring, a male part 14 or a female part 15 is provided at the edge of the 1 / 2 copper wall, and each intermediate component and the end component There are male or female parts at intervals of 180°, and the adjacent two intermediate components are connected by the corresponding male and female parts, the edges of the copper walls are aligned, and the adjacent intermediate components respectively ad...

Abstract

The invention relates to a lubricating-free chain roller, and overcomes the defects that lubricating oil overflow and pollution on a roller and surrounding articles are easily caused by the fact that industrial lubricating oil is added to the existing roller to reduce the friction resistance of the roller and reduce the wear of the roller . The lubricating-free chain roller comprises an outer steel sleeve and an inner copper sleeve which is embedded into the inner wall of the outer sleeve; a graphite mounting part which communicates with the inner wall of the inner copper sleeve is arranged in the inner copper sleeve; graphite is embedded into the graphite mounting part; the graphite is provided with a lubricating surface which is matched with the inner surface of the inner copper sleeve; and the graphite is internally leached with food-grade oil under pressure. The graphite is internally leached with food-grade oil under pressure, so that an enough high lubricating degree between the roller and a sleeve can be ensured, the wear of the roller is reduced, the rotating smoothness of the roller is improved, meanwhile, the lubricating oil can also be prevented from seeping out to pollute the roller and the surrounding articles, and therefore a lubricating-free structure is formed.

Description

technical field [0001] The invention relates to a chain roller, in particular to a lubrication-free chain roller. Background technique [0002] Chain drive is a transmission method that transmits the movement and power of the driving sprocket with special tooth shape to the driven sprocket with special tooth shape through the chain. Chain transmission has many advantages. Compared with belt transmission, there is no elastic sliding and slipping phenomenon, the average transmission ratio is accurate, the work is reliable, and the efficiency is high; the transmission power is large, the overload capacity is strong, and the transmission size is small under the same working conditions; the required tension The tightening force is small, and the pressure acting on the shaft is small; it can work in harsh environments such as high temperature, humidity, dust and pollution. [0003] However, the disadvantages of chain transmission are also obvious, especially the poor transmission...
