Abstract
The present utility model relates to the technical field of driving chains, especially relates to a self-lubricating chain structure having oil storage holes at the two ends of a chain pin and lubricant oil on a chain when running, solving a problem that the driving chains in an engine or an internal combustion engine is easy to worn out because of the shortage of lubricant oil. The self-lubricating chain structure comprising an inner chain plate, an outer chain plate, a sleeve barrel with the two ends fixed on the inner chain plate, a roller packaged in the sleeve barrel and a pin roll riveted on the outer chain plate through the sleeve barrel and the inner chain plate is characterized in that the two ends of the pin roll has concave holes. Working in a transmission room provided with a lubricant oil cup, the concave holes has a function of storing and adhering a certain quantity of lubricant oil, and thus, leakage of lubricant oil can be avoided for chain pulley and chain transmission parts.
Description
Technical field
The utility model relates to the Transmitted chains technical field, especially relates to a kind ofly being provided with oil storage hole at the chain pin two ends, makes chain often with the chain structure of the selflubricating of lubricant oil during operation.
Background technique
Bush roller chain is a device commonly used in the transmission of power, and this product has also had certain standard, but also different in structure, the technological requirement of different workplace chains.At the chain of engine interior effect, because its rotating speed is very fast, temperature is higher, and the wearing and tearing with sprocket wheel in the transmission process are also bigger, and this just needs often to add lubricant oil, yet is difficult to accomplish this point at machine intimate.Chain structure of the prior art is a lot, and its characteristics are respectively arranged, but do not have can be with the structure of lubricant oil work.
As the patent No. is that one kind of ZL99810301.2 can be used for the chain on the elevator mechanism of fork truck carriage, the link components that comprises a plurality of connections in interleaved relation with each other, each link components all comprises a pair of link plate and a plurality of middle shot plate, a kind of chain that can make load uniform distribution between link plate is provided, and under the prerequisite that does not have the load capacity loss, can also substitute a chain with two less chains.
And for example the patent No. is the chain structure of the tenter machine in ZL03221411.1 on-woven machinery, comprise some chain rollers, link the inner chain sheet upper plate that the upper vertical of the some inside and outside chain sheet of each chain roller and each inner chain sheet extends internally and forms, it mainly is to change the original graphite cake between the track of inner chain sheet and tenter machine into roller, be rolling friction thereby become former sliding friction, avoid the wearing and tearing of parts.
For another example the patent No. for the ZL200420012863.2 model utility discloses a kind of many plates symmetry chains, this chain is to be made of inner plate, outer plate, bearing pin and back-up ring, the function such as motion, conveying, lifting, drawing that has possessed the sleeve-barrel roollr chain, in chain structure, cancelled sleeve, two kinds of parts of roller, chain structure is by the combination of many plate symmetries.
Summary of the invention
The purpose of this utility model is in order to solve drive chain that motor or internal combustion engines use owing to lack lubricant oil and problem easy to wear, a kind of structural design of utilizing standard is provided, design the strong blind hole of attached oiliness at the two ends of chain pin, make whole chain in power transmission process, be with lubricant oil often, and not because of lacking the chain structure that lubricant oil causes the selflubricating of chain wear.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the chain structure of this selflubricating, comprise inner plate, outer plate, two ends are fixed on the sleeve on the inner plate, be sleeved on the roller on the sleeve, pass sleeve and inner plate riveting and fix on bearing pin on the outer plate, it is characterized in that the two ends of described bearing pin are provided with concave hole.Work in being provided with the transmission space of lubricant oil lubricating cup, concave hole has the ability of storage and a certain amount of lubricant oil of adhesive tape, and reaching this sprocket wheel chain drive part can oil-break.
As preferably, the concave hole at bearing pin two ends at least respectively has one, and the port size of concave hole is less than the diameter of bearing pin.The degree of depth that concave hole is provided with is set by the diameter of bearing pin, the shape of concave hole or be irregular shape, according to or difficulty of processing and cost determine.
As preferably, the internal diameter of described sleeve is greater than the external diameter of bearing pin, and the internal diameter of roller is greater than the external diameter of sleeve.This structure can adopt standard construction.
As preferably, the length of described bearing pin is greater than the distance between the two parallel mutually outer plate outsides.During assembling, need be to riveting between bearing pin and the outer plate, the bearing pin protrusion outer plate plane after the riveted joint very small size gets final product.
As preferably, described bearing pin two ends and outer plate cooperation place are provided with the shaft shoulder.This is a kind of assembling form, and the bearing pin two ends of this form generally need riveted joint.
As preferably, described bearing pin two ends and outer plate cooperation place are provided with the flat-shaped of cylindrical flat-cut limit, also are provided with the flat-shaped of circular hole flat-cut limit in the corresponding aperture that outer plate matches.This is another kind of embodiment of the present utility model, and two flat-shaped employing interference fit of this structure then need not riveted joint.
Effective benefit of the present invention is: when motor or internal combustion engine, replenish lubricating cup as long as establish one, in the time of just can making chain work, can carry lubricant oil at the shell position that is provided with chain, guarantee stability, the wear resistance of chain sprocket transmission process, prolonged the working life of equipment greatly.
Therefore, the utility model is a kind of reasonable in design, and overall cost is low, can carry the chain structure of the selflubricating of lubricant oil effectively in the chain running.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is a kind of pin shaft structure schematic representation of the present utility model.
Among the figure: 1. inner plate, 2. outer plate, 3. bearing pin, 31. concave holes, 4. sleeve, 5. roller.
Embodiment
