摘要： PURPOSE:To facilitate synchronization of an output shaft with an input shaft by disposing transmission means for forced rotation of the output shaft. CONSTITUTION:An output shaft 12 and a countershaft 37 are disconnected by a hydraulic clutch 36, and hydraulic cylinders 29-32 are operated to return a shifter 21 or 22 to the neutral position. Simultaneously, a hydraulic clutch 34 is connected to forcedly drive the output shaft 12 during a very short time through gears 10, 33, a synchronous transmission shaft 11 and the hydraulic clutch 34, to prevent lowering of rotation of the output shaft 12 due to neutral operation of the shifter 21 or 22 and facilitate synchronization. When the hydraulic clutch 34 is disconnected, the shifter 21 is slid in direction of (a) direction to operate a synchronizing mechanism 23, so that the shifter 21 and an idle gear 15 are connected on synchronizing.

摘要： PURPOSE: To provide a stable synchronous durability for a long period of time by a method wherein a circumferential threaded groove and an axial groove crossing with the threaded groove are arranged in a resin forming layer of synchronous ring.
CONSTITUTION: A synchronous ring is formed by an annular main body 1 and a resin forming layer 2, a circumferential threaded groove 21 and an axial groove 23 crossing with the threaded groove 21 are arranged in the resin forming layer 2 and a pitch P of the threaded groove 21 is in a range 0.5W2.0mm. Thereby, a discharging of lubricant oil is improved and also a wide top land width enables a minute resilient deformation to be performed and further a surface formation is decreased. Therefore, even if the contacted condition with the cooperating conical surface of gear is less, a superior frictional characteristics is provided and a stable synchronous durability can be attained for a long period of time.

摘要翻译：目的：通过周向螺纹槽和与螺纹槽交叉的轴向槽布置在同步环的树脂形成层中的方法，长时间提供稳定的同步耐久性。构成：环状主体1形成同步环，树脂形成层2配置树脂形成层2，周向螺纹槽21和与螺纹槽21交叉的轴向槽23，螺纹槽21在0.5〜2.0mm的范围内。因此，润滑油的排出得到改善，并且宽的顶部区域宽度能够进行微小的弹性变形，并且进一步减小了表面形成。因此，即使与齿轮配合的圆锥面的接触状态较小，也提供了优异的摩擦特性，并且能够长时间地获得稳定的同步耐久性。

摘要： PURPOSE:To heighten the strength, wear-resisting and shock-proofness of a gear by a cementation hardening of an engaging gear portion and a soft nitration processing of a spline gear portion to form processing layers having a specific depth respectively. CONSTITUTION:A cementation hardening is performed on an engaging gear portion 1 to form a cementation hardening layer 0.4-0.9mm. deep. A soft nitration processing is performed on a spline gear portion 2 to form Fe-C-N group compound layer 0.005-0.002mm. deep. It is desirable to connect both gear portions by electron beam welding which has a small heat influence, whereby the transmission gear can obtain enough wear-resisting and shock-proofness at the engaging portion thereof due to a nitriding layer to lessen deficits of teeth, and to stabilize the internal hardness of the spline gear portion.

摘要： PURPOSE:To accomplish the curtailmemt of the width of a coupling sleeve by interposing a special spring member in place of an insert key interposed by a coupling sleeve and a synchronous hub in a Wayner type synchronous gearing device. CONSTITUTION:Transmission gears 11 and 11 are supported on a main shaft 10 through bearings 12 and 12, and a synchronous hub 14 is spline-coupled to the main shaft 10. On both sides of the synchronous hub 14 there are arranged balk rings 15 and 15, and a coupling sleeve 16 is fitted in the spline on the outer periphery of the hub 14. Cutout parts are provided at three positions at the end surfaces on both sides of the synchronous hub 14, and spline teeth of the balk ring 15 are faced therewith. Spring inserting grooves 18 are formed at the central positions in the peripheral direction of these cutout parts, and insert springs 19 are fitted in the grooves 18. The spring 19 is formed by bending a plate spring in a substantially S-shape, and mounted on the sleeve 16 by means of upper and lower engaging parts 19a and 19b at both ends of the spring 19.
