Abstract: The present invention provides an optical connector for coupling one optical fiber wire 18 with another optical fiber wire 18′ in physical contact. The optical connector comprises a receiving portion 21 including a support region 22 adapted to support the optical fiber wires 18, 18′ along the axis of said receiving portion. The axis 24 of the receiving portion is offset from the axis 25 of the optical fiber wire in a posture of being ready to be inserted into the receiving portion 21. When the optical fiber wire 18 is inserted into the receiving portion 21, the inserted optical fiber wire 18 is brought into contact with and bent by a guide region 23, and then the optical fiber wire is slidably moved along the support region 22 of the receiving portion 21. Finally, with keeping the optical fiber wire to be supported by the support region 22, the end of the optical fiber wire 18 is brought into physical contact with the end of another optical fiber wire 18′.

Abstract: According to a lubrication mechanism for a wave gear device 1, frictionally contacting parts 5 of toothed parts of gears 2 and 3 are lubricated using a lubricant with a high base oil viscosity and favorable shear stability. Frictionally contacting parts 7 of the external gear 3 and wave generator 4 and frictionally contacting parts 9 on the inside of wave bearing 42 are respectively lubricated using solid lubricants 8 and 10 that are produced by mixing a low base oil viscosity grease with a resin with low deformation resistance and hardening the mixture by heating. In this way, the lubrication life is extended without causing decreases in the efficiency of the wave gear device.

Abstract: A wave gear drive has a wave generator with a hub and rigid cam plate formed of titanium alloy. Heat-dissipating fins are provided on both sides of these parts, and heat-dissipation is further increased by plating the surfaces with a material having a higher coefficient of thermal conductivity than that of titanium alloy. The result is a lightweight wave gear drive having good heat-dissipating properties that uses titanium alloy, which is stronger and more rigid than aluminum alloy.

Abstract: A lightweight wave gear device has a similar engagement rigidity, tooth surface hardness, and abrasion resistance as when a ferrous material is used. A cup-shaped wave gear device 1 has a rigid internal gear 2 that is formed of a lightweight alloy, such as an aluminum alloy, and internal teeth 21 are formed with a height that is 1.1 to 1.3 times the height used for internal gears that are made of a ferrous material. A hard, electrolessly plated coating is also formed on the tooth surface 21a of the internal teeth 21. By doing so, a lightweight wave gear device can be obtained with a similar engagement rigidity, tooth surface strength, and abrasion resistance to a wave gear device that has a rigid internal gear formed of a ferrous material.

Abstract: A wave gear device does not need to be lubricated. In a cup-shaped wave gear device 1, the inner ring 43 and balls 45 of the wave bearing 42 of the wave generator 4 are made of a ceramic material, while the outer ring 44 of the wave bearing 42 is made of SUJ2 or stainless steel. A DLC coating 302 is formed by a DLC coating process on a rolling surface 48 formed in the inner circumferential surface of the outer ring 44, a DLC coating 303 is formed by a DLC coating process on a rolling surface 47 in the outer circumferential surface of the inner ring 43, and DLC coatings 304 are formed by a DLC coating process on the surfaces of the balls 45. With this, non-lubricated wave gear device can be obtained. Since the agitating resistance of a lubricant can also be eradicated from these parts of the wave bearing, a large decrease can be made in the power loss ratio.
