Title: Belt type continuously variable transmission
Inventor: OBARA TAKAO
IPC: F16C33/34
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To ensure durability, reduce noise at the time of operation, and reduce wear by forming rolling members constituting a rolling bearing of ceramics. SOLUTION: A plurality of balls 21, 21 being rolling members of rolling bearings 3a, 3b, 6a and a plurality of cylindrical rollers 22, 22 being rolling member of a rolling bearing 6b are made of ceramics such as silicon nitride. With this constitution, the rigidity of each of bearings 3a, 3b, 6a, 6b is enhanced without reducing the diameters of the rollers 22, 22 as well as the balls 21, 21 and increasing the numbers thereof. Consequently, a basic dynamic rating load is increased to ensure durability. Furthermore, irrespective of the load applied during operation, shifting in the positional relation between both mutual rotational shafts 1, 2 on the input and output sides can be restrained, thereby reducing generation of noise and wear during operation.
