Abstract

PURPOSE:To permit uniform lubrication for a chain and permit proper oil feeding by installing a lubricating apparatus equipped with an operation means which operates at every pitch in prime-number relation for the number of chain pitch, onto an apparatus for lubricating a chain tightened in free revolution. CONSTITUTION:When an endless chain 9 revolves continuously, a chain wheel 10 allows an operation piece 12 to pass in front of an approach switch 15 at an intervals of a prime number P2 for a chain pitch number P1, and excites an electromagnetic actuator 16. The oil feeding pump 17 of a lubricating apparatus 19 feeds the lubricating oil in an oil tank 18 into the chain 9 each time when the actuator 16 is excited. During the time when the chain repeates revolution by the amount P2, the pump 17 feeds oil P1 times at an equal intervals, and the lubrication for all the pitch of the chain 9 is uniformly executed. An electronic pulse counter for detecting the revolution of the chain 9 may be used in substitution for using the chain wheel 10, operation piece 12, and the switch 15 as operating means.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a means for supplying lubricating oil to an endlessly connected and rotating chain, and more particularly to a means for unevenly supplying lubricating oil to each link of a high-speed rotating chain.

A conventional example of a device for supplying lubricating oil to the sliding parts of a rotatably mounted chino will be described with reference to FIG. 1.2. A checker arm 2 for operating the refueling pump is pivotally attached to a refueling pump 1 that communicates with a refueling tank (not shown) so as to reciprocate in a fan shape, and is disposed above a rotatable chino 6. The checker arm 2 is dug through the bracket 5 at a height where the checker arm 2 and the checker roller interfere with the bush and the roller 4 so that the checker arm 2 and the checker roller reciprocate along the rotating direction of the checker 73. A lubrication nozzle 6 communicating with the discharge side of the lubrication pump 1
The checker arm 2 is separated by a distance that is an integral multiple of the length of the checker arm 2 and faces 1 Mi between the outer link 7 and the inner link 8 or between the inner link 8 and the roller 4 to serve as a lubricating machine.

In this lubricating machine, the roller 4 of the rotating naen 6 interferes with the checker arm 2 to operate the lubricating pump 1, and the lubricating oil discharged from the lubricating pump 1 is directed from the lubricating nozzle 6 to the sliding part of the cheno 3. Inject □ to lubricate.

However, according to the above-mentioned device, the checker arm 2 for pump operation and the roller 4 of the naen 3, which rotates at daytime speed, frequently interfere with each other, and the impact is large, resulting in breakage of the checker arm 2 and roller 4. Due to severe deformation and wear, and the fact that the lubricating pump 1 is operated infrequently, even if the amount of lubricating oil discharged by the lubricating pump 1 increases or decreases by a small amount, the rotating cenograph 31C may be overfilled with lubricant. It was difficult to adjust the discharge amount because it sometimes became too small.

In view of the drawbacks of the above-mentioned oil supply means, the present invention regulates the operating frequency of the oil supply bonder with respect to the rotation of the chain.
, /:y a>Amount of fruit. The object of the present invention is to provide a lubricating means that can perform proper lubricating and has a long service life as a lubricating pump.

P2 which has a prime number relation to Czebicchi number P1
% that a lubrication system with actuation means for each pitch is provided.
This is a unique oil supply system.

The configuration of this invention will be explained with reference to FIG. Let Pl be the total number of pitches of the rotating endless chino 9, and when Pl is multiplied by P2, it is a prime number 'lP2 that produces an integer remainder. A rotatably tensioned endless chain wheel 9 made of a number of pinches P1 is wound around a chain wheel 10 of one tooth number P2 to form a conveyor 11, and S
Combine P1 and P2 so that they are prime numbers.

A ferromagnetic actuating piece 12 is connected to the chain wheel 1o via a non-magnetic support plate 16 so as to rotate it four times. The frame 14 of the conveyor 11 includes a proximity switch 15 facing the rotational orbit of the operating piece 12, an electromagnetic actuator 16 electrically connected to the contact switch 15, and a piston rod 17A connected to the magnetic core of the electric actuator 16. Provide a refueling pump 17 connected to the The discharge nozzle 17B of the oil supply pump 17 is opened facing above the endless chino 9. An oil tank 18 is provided on top of the oil supply bomb 17 and communicates with it to form a lubricating device 19.

The operation of the above configuration will be explained next.

When the endless chain 9 rotates continuously, the chain wheel 1° causes the actuating piece 12 to pass in front of the proximity switch 15 at intervals of i P 2 with respect to the chain chain number P1 to excite the electromagnetic actuator 16. . The oil supply pump 17 supplies lubricating oil in the oil tank 18 to the endless chino 9 every time the ml actuator 16 is excited. Endless Cheno 9 is P
The oil supply pump 17 performs oil supply operation 21 times at equal intervals, and lubricates all pitches of the endless chino 9 evenly.

Although a chain wheel 1°, an operating piece 12, and a proximity switch 15 are provided as an operating device for the oil supply pump 17, the oil supply bonder 17 is connected to an electronic pulse counter that detects rotation of the endless chain.
may be connected and operated.

As explained above, this invention provides a rotating chain with a pitch Li Pl with a lubricating device that operates every P2 pitches, which is a prime number with Pl, so that the lubricating device operates while one chain rotates P2 times. Since lubrication is repeated 21 times for every P2 pitch, it is now possible to lubricate all the pitches of the chino unevenly, regulate the operating frequency, and easily supply the appropriate amount of lubrication.
