Abstract

PURPOSE:To soften the noise in belt traveling and prolong service life by forming the edge surface of a tip body into conical or truncated conical form and allowing the tip body to revolve together with a pin and using the metal material having the large vibration suppressing effect as basic material. CONSTITUTION:A tip body 40 engaged with the wall surface of a V-pulley is a cylindrical body fitted onto the both edges of a pin 30 projected from the outer wall 12 of a main link plate 10 on the outermost side, and the edge surface in contact with the wall surface of the V-pulley has a conical or truncated conical form, and the tip body 40 is rotatable in coincidence with the axis center of the pin 30, and made of the metal material having the vibration- suppressing effect. Therefore, even if the tip body 40 contacts the wall surface of the V-pulley through vibration, the collision noise is softened, and since the press contact turn of the contact line between the tip body 40 and the V- pulley is not generated, the generation of squeak noise is suppressed. Further, in the intrusion and slip-off from the V-pulley, the intrusion and slip-off can be made smooth by slight rotation, and noise can be reduced, and the eccentric abrasion of the edge surface can be decreased by the change of the ridge line in contact.

Furthermore, a belt in which both ends of the pin connecting the link plays 1 to 3 groups are tapered and engage with the wall surface of the V-pulley is also disclosed, for example, in Japanese Utility Model Application No. 63-37846.
This type of belt can transmit sufficient power by increasing the diameter of the pin6.In addition, as other chain belts, there are freely movable tips on both ends of the pin that connects multiple link plate groups. When the belt enters the pulley, the end surface of the tip body conforms to the side wall of the pulley, and the tip body itself rotates to prevent vibration, rolling, or collision when the belt enters the pulley. An application to alleviate the situation was previously filed by Ganjin Toyama.

(Problem to be Solved by the Invention) The chain type bells 1 to 1 are designed so that the tip body rotates slightly around the pin, so that the belt does not enter the pulley or the pulley moves under particularly high load transmission conditions. When detached from the tip, the tip tries to rotate actively. This is because the lateral pressure or the tensile force in the longitudinal direction of the belt applied to the contact line between the pulley side wall and the tip body is dispersed in different magnitudes at this contact line, which generates a rotational moment in the tip body. be. As a result, it was revealed that the chip body rotates at the fitting portion of the pin, generates heat, causes fatigue failure at an early stage, and also generates noise when traveling from Pel 1 to Pel 1.

Furthermore, if the end face of the chip body is constantly subjected to large lateral pressure, the cylindrical part of the chip body will deform in the direction away from the pin, reducing the clipping force between the chip body and the pin, and as a result, the chip body will be forced to press the pin more than necessary. The present invention aims to improve these problems, and improves the material of the chip body to reduce the noise during running. It is an object of the present invention to provide a chain-type power transmission bell 1 which can reduce the power consumption, maintain the grip force between the tip body and the pin, and have a long life.

The chip body 40 that engages with the wall surface of the V pulley is connected to the pin 3 that protrudes from the outer wall 12 of the outermost main link play 1.
It is fitted on both ends of 0. The tip body 40 is a cylindrical body, and the end surface that contacts the wall surface of the pulley is conical or truncated conical (in this embodiment, only the conical shape is shown), and the apex angle is It is the same as the apex angle, and its axis coincides with the axis of the pin 30. Further, the chip body 30 is rotatable with respect to the link plate, so the chip body 40 is fitted and fixed to both ends of the pin 30 and the chip body 40 is rotated together with the pin 30, or the chip body 40 is attached to the pin 30. Although it is possible to rotate the tip body 40 very slightly with respect to the pin 30, it is preferable to rotate the tip body 40 together with the pin 30 as in the present invention because the fitting portion of the tip body does not wear out.

The chip body 40 used here is made of a metal material with a large vibration damping effect, such as Ti-50%Ni alloy, Fe50%
Co-based alloy, Fe-(1,0-20%) Cr-based alloy,
Examples include Cu40%Mn alloy. All of these have an inherent damping capacity of 30% or more and have a large vibration damping effect. As described above, since the chip body 40 is made of a metal abrasive material with a large vibration damping effect, even if it does not vibrate and comes into contact with the wall surface of the pulley, the rattling noise etc. generated at that time is attenuated. On the other hand, however, it lacks wear resistance, so as shown in Figure 3, the end face 41 that contacts the wall of the pulley is coated with a wear-resistant layer of about 50 to 1.00 μm by ceramic electrolytic plating, thermal spraying, baking, etc. A layer 42 may also be provided.

Next, FIG. 4 shows another embodiment of the chip body 40, in which the pin 3
A reinforcing ring material 44 is attached to the outer circumferential surface of the cylindrical portion 43 of the chip body 40 fitted to the end portion of the cylindrical portion 40 . The material of the reinforcing ring material 44 is different from the material of the chip body itself and has relatively high strength, such as chromium molybdenum steel (JTS SCM class) or alloy tool steel (JIS SCM class).
KD class), etc. With this configuration, even if the chip body 40 receives a large lateral pressure and the cylindrical portion 43 tries to deform in the direction away from the pin 30, the reinforcing ring material 44 prevents this, so the clipping force of the chip body 40 is reduced. It's hard to do. Note that the material of the chip body 40 used here is a metal material with a large vibration damping effect as described above.
The end face of the tip body is conical or truncated conical (the conical shape is not shown here).The end face of the dip body 40 has a wear-resistant coating with a thickness of about 50 to 100 μm as shown in FIG. A layer 42 may also be formed.

Next, the reinforcing link 44 is inserted into the chip body 4 as shown in FIG.
It may be firmly fixed to the inner circumferential surface of the cylindrical portion 43 of 0. Even with such a configuration, deformation of the cylindrical portion 43 in the direction away from the pin 30 is prevented, the grip force is not reduced, and the reinforcing link material 44 is interposed when the chip body 40 is inserted into the pin 30. Therefore, the cylindrical part 43 of the chip body is not subjected to direct stress and is difficult to break.7 Also in this case, as shown in FIG.
It can be covered with a wear-resistant layer 42 of the order of μ.

Next, FIG. 8 shows still another embodiment of the chip body 40, in which the end face of the chip body 40 and the outer peripheral surface of the cylindrical part are coated with a protective layer 50. This prevents wear and reinforces the cylindrical portion 43. Protective layer 5
The material 0 has wear resistance and high strength, and examples include a nitride layer or oxide layer such as AI or Cr-Ti. In this case, as shown in FIG. 9, a reinforcing ring material 44 may be attached to the inner circumferential surface of the tip body cylindrical portion 43.

(Effects of the Invention) As described above, in the chain-type power transmission bells 1 to 1 of the present invention, the tip body fitted to both ends of the pin is formed of a metal with a large vibration damping effect. Since it does not vibrate, the collision noise is reduced even when it comes into contact with the wall of the V-pulley.
It is excellent in terms of noise, and since the end surface of the tip body is conical or truncated, the contact line between the tip body and the pulley does not press and turn, so there is no accompanying squeak noise. Furthermore, since the tip body is rotatable about the axis of the bottle, it rotates slightly when it enters the V-pulley and when it leaves the V-pulley, smoothing the entry and exit process and reducing noise. The ridge line constantly changes to reduce uneven wear on the end face of the chip body.

When a reinforcing link material is installed on the outer or inner circumferential surface of the chip body surface, it prevents the deformation of the cylindrical part of the chip body, maintains the gripping force of the chip body, and prevents wear caused by rotation of the chip body. Also, it is possible to obtain a belt with a long life by eliminating the possibility of separation from the pin.
