摘要:
A tensioner lever for a chain or belt power transmission comprises a resin shoe having a shoe surface on which the chain or belt slides, and a back surface with a plunger-engaging part adjacent one end and a lever shaft bearing adjacent the other end. A shape-retaining groove extends longitudinally along the shoe through the plunger engaging part and the lever shaft bearing. A part of a strength-maintaining plate is fits in the shape-retaining groove and a part of the strength-maintaining plate is exposed.Simplification and weight reduction in the tensioner lever can be realized, and molding accuracy requirements are reduced. Assembly is simplified by pawls formed in openings in a side wall of the shoe, which cooperate with locking holes in the strength-maintaining plate. The pawls simplify disassembly for recycling and may be notched so that they can be broken away. A projection is provided on the plunger-engaging part of the shoe for limiting lateral deviation of the lever relative to the tensioner plunger.

A movable lever for a transmission chain, which is able to pivot smoothly, and avoid seizing on its supporting shaft, comprises a unitary, molded resin lever body composed of a chain-engaging shoe and a plate-receiving portion, and a reinforcing plate in a slot in the plate-receiving portion. The plate and the plate-receiving portion have coaxial, cofastening mounting holes which receive the mounting shaft. Reinforcing ribs are provided on a side of the plate-receiving portion and their ends are notched to provide grooves which promote the flow of oil, which accumulates on the lever, toward the mounting holes so that adequate lubrication of the mounting hole in the plate is achieved.

There are provided a ceramic electronic component and a method for producing the ceramic electronic component, where a ground electrode layer can be directly coated with lead-free solder without lowering reliabilities. Terminal electrode 3 is provided with a ground electrode layer 21 of Cu having been formed by firing, a solder layer 22 formed of a lead-free solder based on five elements of Sn—Ag—Cu—Ni—Ge, and a diffusion layer 23 having been formed by the diffusion of Ni between the ground electrode layer 21 and the solder layer 22. Because the diffusion layer 23 of Ni is formed between the ground electrode layer 21 and the solder layer 22, the diffusion layer 23, which functions as a barrier layer, suppresses the solder leach of Cu from the ground electrode layer 21. The diffusion layer 23 of Ni can also suppress the growth of fragile intermetallic compounds of Sn—Cu. Therefore, a decrease in the bonding strength between the ground electrode layer 21 and the solder layer 22 can be prevented.

A guide for an engine timing chain comprises a metal supporting base and a resin shoe, the shoe having integrally formed hooks for attachment to the supporting base, and integrally formed side walls for limiting lateral movement of the chain on the sliding contact surface of the shoe. A central portion of the shoe has a sandwich injection molded structure and comprises a high strength core of glass fiber-reinforced polyamide resin, and a polyamide skin layer. The side walls and the hooks are formed entirely of the skin layer material.

A synthetic resin guide for a transmission device comprises an elongated rail for longitudinal sliding engagement with a power transmission medium, and a rail supporting member molded as a unit with the rail. The supporting member comprises a plurality of reinforcing ribs which support the rail. The ribs are distributed along the length of the transmission device from a location adjacent one end of the rail to a location adjacent the opposite end of the rail. The guide is formed by injection molding and the reinforcing ribs extend in directions following the flow of synthetic resin during injection molding. Preferably the synthetic resin is a glass fiber reinforced resin. By forming the reinforcing ribs in this manner, high strength and toughness are imparted to the guide, and warpage and torsion, which would otherwise be encountered in a high temperature transmission environment, are reduced.

A movable guide for a flexible, endless, traveling transmission medium such as a timing chain is formed by sandwich molding and incudes a boss for receiving a shaft on which the guide is pivotable. The boss is composed of a plurality of concentric circular ribs and a plurality of radial connecting ribs, which connect the circular ribs. The resin charging port of the mold is located in an end wall of the mold cavity near the location at which the boss is formed. One of the connecting ribs preferably extends perpendicularly toward the sliding contact surface of the guide shoe.

In a sliding contact guide for a drive chain or other flexible transmission device, a guide body includes a shoe 102 and a slotted, plate-receiving portion 102 integrally molded on the back of the shoe. A reinforcing plate is inserted into the slot. The guide body has a mounting hole near one end for receiving a mounting shaft. The reinforcing plate, on the other hand, has an arcuate bearing portion which extends only part way around the mounting shaft.
