Problems solved by technology

At this time, the stress applied to the outer ring of each bearing may be locally concentrated due to the installation position of the bolt for fixing the stopper plate. When the stress is excessively concentrated, the outer ring is deformed, and the life of the rolling bearing is reduced. question

Embodiment Construction

[0016] Next, preferred modes for implementing the present invention will be described using examples.

[0017] figure 1 It is a configuration diagram showing a schematic configuration of a power transmission device 10 equipped with a belt type continuously variable transmission 20 according to an embodiment of the present invention. The power transmission device 10 is a device that is mounted on a vehicle and transmits power from an unillustrated engine to the axle shafts 19a, 19b of the left and right wheels. The output shaft of the engine is connected; the forward and reverse switching unit 14 is used to switch the rotation direction of the output shaft of the hydraulic torque converter 12 between the forward direction and the reverse direction; the belt type continuously variable transmission 20 (hereinafter referred to as "CVT") ”), the power on the main shaft 22 side is continuously variable and output to the counter shaft 32 side through the belt 21, and the above-menti...

Abstract

A belt type continuously variable transmission includes a primary shaft and a secondary shaft, wherein the primary shaft is supported on a case via a first rolling element bearing, and the secondary shaft is supported on the case via a second rolling element bearing, the case is formed with a bolt hole at each of an even number of locations in a region separate from a shaft center plane, which is a plane that passes through a shaft center of the primary shaft and a shaft center of the secondary shaft, and first and second stopper plates that each hold down outer races of the first and second rolling element bearings are fixed to the case by bolts mounted in the bolt holes.

Description

technical field [0001] The present invention relates to a belt-type continuously variable transmission, and in detail, relates to a belt-type continuously variable transmission having: a primary shaft for inputting power, and a secondary shaft parallel to the main shaft The arrangement is such that the power input to the main shaft is continuously variable and transmitted via a belt; the main shaft is supported on the housing via a first rolling bearing, and the sub shaft is supported on the housing via a second rolling bearing. Background technique [0002] In the past, as such a belt-type continuously variable transmission, a proposal has been made in which a transmission is accommodated in a case (for example, refer to Patent Document 1), and the transmission has: a main shaft for inputting power from an engine; a counter shaft, The power input to the main shaft is transmitted to the counter shaft via an endless belt continuously variable speed. In this transmission, rol...
