摘要： PROBLEM TO BE SOLVED: To provide a belt type continuously variable transmission which can prevent a belt from single-sided contacting without heightening the mounting accuracy of a bearing and the bearing rigidity, compared with a conventional arrangement, and can preclude deterioration of the transmission performance and drop of the belt lifetime without increasing cost. SOLUTION: Either an input 3 or an output pulley 4 consisting of stationary sheaves 31 and 41 and movable sheaves 32 and 42 is mounted by the floating structure having a degree of freedom in the axial direction relative to the shafts 1 and 2. Thereby the axial direction position of the floating pulley member is automatically adjusted optimally using the axial direction position of the fixed pulley as the reference without requiring a high accuracy in the mounting position of the supporting bearing or with eventual change in the position of the bearing caused by an external force, and a belt 5 can be prevented from single-sided contacting.

摘要： PROBLEM TO BE SOLVED: To provide a sealing device to set a labyrinth gap to provide desired seal performance without being influenced by mechanical machining precision. SOLUTION: A filler 11 is fixed to a seal member 1 and an outer ring 3 by filling a gap between an outer ring 3 and the stepped part 10 of a seal member 1 with the filler after the outer peripheral wall 2C of a slinger 2 is coated with a mold release agent. Through rotation of a slinger 2 based on the seal member 1, the mold release agent is removed and a labyrinth gap LSI is formed between the filler 11 and an outer peripheral wall 2C of the slinger 2. A labyrinth gap LS1 is not influenced by mechanical machining precision of the outer peripheral wall 2C of the slinger 2 and the stepped part 10 of the seal member 1.

摘要： PURPOSE:To prevent generation of peeling or cracks in a track surface by forming a recessed surface to prevent an excessive stress applied to the track surface by thermal expansion in a shaft diameter direction in an inner circumference of an inner ring. CONSTITUTION:A recessed surface 20 facing in a diameter direction to a track surface 11a is formed along the whole circumference almost at a center part of an inner circumferential surface of an inner ring 11. Even when a shaft 1 is thermally expanded by a temperature rise by the recessed surface 20, an outer circumference of the shaft 1 becomes hard to contact with the track surface 11a under it, so generation of a large circumferential stress at the track surface 11a can be prevented. If a load from a ball 13 is applied on the track surface 11a, generation of peeling or cracks can be prevented. The circumferential stress is generated on both sides of the recessed surface 20 to a certain degree, but because there is no direct application of a load by roll of the ball 13 here, bad effects are not given to the track surface 11a. By providing a large interference at the parts, therefore, desired engagement can be secured even under a low temperature.

摘要： PURPOSE:To restrict the rotation of a pinion gear by means of sliding frictional force caused by tapered roller bearing, and thereby restrict differential movement between paired drive shafts by intersecting the extension of a generating line of an outer ring raceway surface with the extension of the generating line of an inner ring raceway surface at a position isolated from the axial center of the bearing in a plane including the axial center of the tapered roller bearing. CONSTITUTION:In a plane including the bearing axial center alpha of a tapered roller bearing 9, the extension 7 of the generating line of an outer ring raceway surface 93a is intersected with the extension gamma of the generating line of an inner ring raceway surface 91a at a position A isolated from the bearing axial center alpha. By this constitu tion, a tapered roller 10a is rotated while its inclination is being restricted, the circum ferential surface of the tapered roller 10a and each raceway surface 19a and 93a are thereby mutually slid, so that frictional force is caused between them. Frictional force is also caused between the end face of the tapered roller 10a and a collar section. In this case, the aforesaid sliding frictional resistance is turned out to be the rotational resistance of the tapered roller bearing 9, so that the rotation of a pinion gear is thereby restricted. By this constitution, differential movement between paired drive shafts connected to each side gear is thereby restricted.

摘要： PROBLEM TO BE SOLVED: To improve the load bearing characteristic and anti-seizing characteristic with respect to a supporting bearing 15 of a cylinder shaft 2 having a movable flange 7. SOLUTION: A belt 8 is hung between opposite faces of a fixed flange 6 integrally formed on one end side of a rotating shaft 1, and the movable flange 7 integrally formed on one end side of the cylinder shaft 2 externally mounted on an outer diameter of the rotating shaft 1 in a state of being integrally rotatable and axially slidable, and a wrapping diameter of the belt 8 can be variably adjusted by axially displacing the movable flange 7 with the cylinder shaft 2 by a feed screw mechanism 10. The rolling bearing 15 for supporting the cylinder shaft 2 is a lubricant-filled angular ball bearing. Whereby the supporting rigidity of the cylinder shaft 2 is improved and the heat generation is inhibited in comparison with a conventional case using a deep groove ball bearing.
