Abstract

The utility model relates to an oil-free chain, which is provided with an upper chain plate and a lower chain plate; a rolling wheel is fixed at each of both ends between the upper chain plate and the lower chain plate; rolling wheel cover plates and rolling wheels are arranged between the rolling wheel and the upper and lower chain plates; a pin shaft holes in which pin shafts can be installed are arranged at the position of the rolling wheel cover plates corresponding to the upper and lower chain plates; solid lubricating bearings which can directly contact with the pin shafts are arranged tightly close to the inner walls of the rolling wheels. The utility model uses a multi-section oil-free lubricating chain to connect into a transmission chain for a heat-setting machine, can continuously work under the condition of high temperature, has no need of lubricant, reduces expense of production and maintenance and working intensity, and has no pollution to fabric and environment, and has stable running and no noise.

Description

The oil-free lubrication chain

The utility model relates to field of textile machinery, particularly relates to the selvage guide drive chain of heat setting machine.

Heat setting machine as fabric heat setting, its work is the drying room in 200 degree left and right sides temperature, the rotating part that is used for the chain of selvage guide transmission is to adopt ball bearing, the more piece chain connects by the bearing pin that is coupling in ball bearing, and during the transmission of the chain of selvage guide transmission, constantly produces friction between ball bearing and bearing pin, running continuously under said temperature, must between bearing and bearing pin, constantly inject high temperature resistant luboil, otherwise the active part of chain just killed easily, or doubled wearing and tearing.But because temperature is up to 200 degree in the drying room, high temperature resistant luboil is volatile, can only frequently refuel.When oil gas reaches finite concentration in the drying room, pollute fabric easily, particularly light fabric, and discharge drying room as oil gas and pollute the environment.And in some import types and domestic imitative import type, the ball bearing of its selvage guide drive chain adopts entad single-row ball bearing, must add high temperature resistant lubricating grease, otherwise just kill easily, ball bearing is fallen apart, but high temperature resistant lubricating grease costs an arm and a leg, the import of still needing at present, and it is bigger to produce maintenance cost.

The purpose of this utility model is the shortcoming at the selvage guide drive chain of present domestic heat setting machine, import heat setting machine and imitative import machine, designs a kind of lubricating oil filling and low oil-free lubrication chain of production maintenance cost of not needing.

The technical solution of the utility model is: the oil-free lubrication chain has upper link plate and following carrier bar, two ends between upper and lower two blocks of carrier bars respectively are fixed with a roller, be equipped with the roller cover plate between roller and upper and lower carrier bar, roller, its corresponding upper and lower two carrier bar positions of roller cover plate have the pin shaft hole that bearing pin can be installed, and are close to the roller inwall and are provided with the bearing with solid lubricant that can directly contact with bearing pin.

As further technical measures of the present utility model, aforementioned bearing with solid lubricant is formed by the composite material moulded sintering of copper radical self-lubricating.

Advantage of the present utility model is: more piece chain described in the utility model is connected by bearing pin becomes the selvage guide drive chain, in the drying room of 200 degree high temperature, work, after the on-stream break-in of bearing with solid lubricant between bearing pin and roller, can produce one deck solid lubricant film, because bearing with solid lubricant material friction coefficient is little and self lubricity preferably, do not need lubricating oil filling, reduce and produce maintenance cost and working strength, and to fabric, environmental nonpollution, the steady noise free of running.

Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail:

Shown in Figure 1, be the structural representation of the utility model specific embodiment;

Shown in Figure 2, be connected to the schematic representation of selvage guide drive chain for chain described in the utility model;

Shown in Figure 3, the structure cross-sectional schematic when being in coupled condition for the utility model shown in Figure 2.

Among Fig. 1, the oil-free lubrication chain has upper link plate 1 and following carrier bar 2, two ends between upper and lower two blocks of carrier bars respectively are fixed with a roller 3, be equipped with roller cover plate 4 between roller 3 and upper and lower carrier bar, roller 3, roller cover plate 4 its corresponding upper and lower two carrier bar positions have the pin shaft hole 5 that bearing pin 7 can be installed, be close to roller 3 inwalls and be provided with the bearing with solid lubricant 6 that can directly contact with bearing pin 7, this bearing with solid lubricant 6 is formed by the composite material moulded sintering of copper radical self-lubricating.

Fig. 2 has represented more piece oil-free lubrication chain described in the utility model is connected to the mode of selvage guide drive chain, and more piece oil-free lubrication chain is formed by connecting by bearing pin 7, chain clamping plate 8.
