Bevel gear transmission

A bevel gear drive (1) comprising:

• a spur bevel gear (2),
• a pinion that meshes with the spur bevel gear (2),
• the spur bevel gear (2) and the pinion being arranged within a housing (3),
• a circular-segment-shaped abutment plate (4) being fixed to the housing, and
• a support surface of the abutment plate (4) being located adjacent and spaced from an outer diameter of the spur bevel gear such that during a first operating condition when the spur bevel gear (2) is operating under high load, the spur bevel gear (2) still remains spaced from the support surface of the abutment plate (4);
• and
• during a second operating condition, the spur bevel gear is axial displaced towards, contacts and is supported by the support surface of the abutment plate so as to avoid further axial displacement of the spur bevel gear (2) when forces acting upon the spur bevel gear (2) result in axial displacement thereof.

A bevel gear drive of a transmission comprising:

• a housing;
• a spur bevel gear;
• a pinion having teeth meshing with teeth of the bevel gear for rotating the spur bevel gear with respect to an axis of the pinion;
• the bevel gear and the pinion being arranged within the housing;
• a circular-segment-shaped abutment plate being fixedly secured to a surface of the housing and the abutment plate comprising a support surface facing the spur bevel gear;
• during a first operating condition of the bevel gear, the support surface of the abutment plate normally being spaced from the bevel gear by a gap so that the bevel gear remains spaced from the abutment plate;
• and
• during a second operating condition of the bevel gear, the bevel gear being axially displaced toward and into engagement with the abutment plate so that the support surface of the abutment plate contacts and supports a portion of the bevel gear and thereby prevents further axial displacement of the bevel gear toward the housing.
