Precision bevel gear transmission

Abstract

The invention relates to the technical field of gears, in particular to a transmission gear. In the transmission, gears are generally adopted as a transmission part. The gear transmission is precise and high in efficiency. A spiral bevel gear transmission is often used in aerospace and transportation industries. The spiral bevel gear transmission has high transmission coefficient, large arc overlap coefficient, and smooth and steady transmission. Adopting the spiral bevel gear for transmission requires the cooperation of each part. The others parts of the spiral bevel gear transmission includea main shaft, a fixed cone lower lining plate, a fixed cone upper lining plate, an upper frame, a pressing sleeve, a buffer sound-proof layer, and a damping and cooling layer, wherein the fixed conelower lining plate is arranged on the outer side of the main shaft; the fixed cone upper lining plate is arranged on the top portion of the fixed cone lower lining plate; the upper frame is arranged on the top portion of the fixed cone upper lining plate; the pressing sleeve is arranged on the top portion of the upper frame; the buffer sound-proof layer is arranged on the outer side of the inner wall of the main shaft; and the damping and cooling layer is arranged on the outer side of the buffer sound-proof layer.

Description

technical field [0001] The invention relates to the technical field of gears, in particular to a precision bevel gear transmission. Background technique [0002] Gears have various structures, such as spur gears, helical gears, bevel gears, worms, etc. [0003] Widely used in various fields of production and life, such gears generally occupy a large space with the transmission structure, the transmission efficiency is not very high, the transmission noise is large, the bearing torque is small, and generally can only be transmitted in the parallel or vertical direction. Power, for some occasions where the space is relatively compact, and high transmission efficiency and large bearing torque are required, the general gear structure cannot be suitable for special needs. The movement and power transmission between the spiral bevel gear work smoothly, the transmission ratio is large, the transmission power is large, and the structure is compact. Among them, hypoid gears with of...

[0003] Widely used in various fields of production and life, this kind of gear and transmission structure generally occupies a large space, the transmission efficiency is not very high, the transmission noise is large, the bearing moment is small, and generally can only be transmitted along the parallel or vertical direction For power, for some occasions where the space is relatively compact and high transmission efficiency and large load-bearing torque are required, the general gear structure cannot be applied to special needs. Spiral bevel gears are spiral bevel gears, which are often used in two-phase intersecting shafts Between motion and power transmission, the spiral bevel gear works smoothly, has a large transmission ratio, large transmission power, and compact structure. It is a transmission device widely used in various machines and equipment, and is the most complicated type of gear transmission.
