Definitions
- the present invention relates to a belt-type continuously variable transmission, and more specifically, a primary shaft to which power is input and power that is arranged in parallel to the primary shaft and is input to the primary shaft is steplessly changed via a belt.
- a secondary shaft that is transmitted through the belt, and supports the primary shaft to the case via a first rolling bearing and supports the secondary shaft to the case via a second rolling bearing.
- the present invention relates to a step transmission.
- the belt-type continuously variable transmission In the belt-type continuously variable transmission described above, the power input to the primary shaft is transmitted to the secondary shaft via the belt. Therefore, the belt-type continuously variable transmission is arranged on the shaft center plane that is a plane passing through the shaft center of the primary shaft and the shaft center of the secondary shaft. Along with this, the tension of the belt and the centrifugal force accompanying the rotation of the belt are applied to the primary shaft and the secondary shaft. For this reason, the load acting on each rolling bearing becomes larger in the direction along the axial center plane. At this time, depending on the tightening position of the bolt for fixing the stopper plate, the stress applied to the outer race of each rolling bearing may be partially concentrated, and if the stress is excessively concentrated, the outer race will be deformed. As a result, problems such as a reduction in the life of rolling bearings may occur.
- the main purpose of the belt-type continuously variable transmission of the present invention is to prevent excessive stress from acting on the rolling bearings in a partially concentrated manner.
- the belt type continuously variable transmission according to the present invention employs the following means in order to achieve the above-mentioned main object.
- the belt type continuously variable transmission of the present invention is A primary shaft to which power is input, and a secondary shaft that is arranged in parallel to the primary shaft and to which power that is input to the primary shaft is transmitted in a stepless manner via a belt.

- the first and second stopper plates that respectively press the outer races of the first and second rolling bearings are fixed to the case by bolts that are attached to the bolt holes.
- the primary shaft to which the power is input is supported via the first rolling bearing and the secondary shaft is supported via the second rolling bearing.
- First and second bolt holes are formed in each of the regions that are out of the axial center plane that is a plane that passes through the axial center of the axial center and the secondary shaft, and the outer races of the first and second rolling bearings are respectively pressed.
- the stopper plate is fixed by a bolt attached to the bolt hole. As a result, the tightening position of the stopper plate fixing bolt can be set to a region deviated from the axial center plane.

- the region where the load received by each rolling bearing is larger overlaps with the region where the restraining force applied to the outer race is larger, and the outer race is partially excessive. Stress may be concentrated.
- the “first and second rolling bearings” may be ball bearings.
- the “belt type continuously variable transmission” may be an in-vehicle belt type continuously variable transmission. In a belt-type continuously variable transmission for in-vehicle use, since the transmitted power is large, the load received by each rolling bearing tends to increase. On the other hand, there is a tendency for more compact rolling bearings to be used due to severe space constraints, and it is often difficult to ensure sufficient reserve against excessive stress. high.
- the even-numbered bolt holes are formed in the case so as to be paired with the axial center of the primary shaft or the axial center of the secondary shaft as a symmetrical axis. It can also be formed in a region where an angle formed by a plane passing through the centers of the bolt holes and the axial center plane is within a range of approximately 70 degrees to approximately 110 degrees.
- the restraining force acting on the outer race tends to be larger in a region along the plane passing through the centers of the bolt holes, but the angle formed by the plane passing through the centers of the bolt holes and the axial center plane is approximately 70.
- the bolt holes may be formed in pairs at positions where the angle is approximately 90 degrees.
