Problems solved by technology

However, ordinary rubber is prone to aging and damage under the action of oil, temperature, and cyclic stress, so the service life of this kind of gear is much shorter than that of ordinary forged steel gear, and it is not suitable for use under harsh working conditions.

Embodiment Construction

[0024] A kind of metal rubber flexible web gear of the present invention, as figure 1 , 2, which specifically includes: ring gear 1, retaining ring 2, wheel hub 3, key 4 and metal rubber block 5, etc., the ring gear 1 is evenly punched with a rectangular through hole along its inner diameter and circumference; The ring 1 is designed separately, and there is a keyway at the position corresponding to the through hole of the ring gear; the key 4 is matched with the keyway of the hub 3, and it is connected with the hub 3 through the hexagon socket head screw 7; the metal rubber Block 5 is embedded in the gap formed by hub, key and ring gear. During the normal operation of the gear, the metal rubber will be squeezed when the hub and the ring gear rotate relative to each other. Since the metal rubber has certain elasticity and good damping characteristics, the above design can realize the vibration reduction and vibration isolation of the metal rubber flexible web gear. characteris...

Abstract

The invention relates to a metal rubber flexible radials gear, which is characterized in that: a gear ring which is evenly provided with rectangular through holes along the internal diameter and the circumferential direction; a hub which is designed to be separated from the gear ring, the position where is corresponding to the gear ring is provided with a keyway; the gear ring and the hub are ensured to be capable of rotating relatively in a certain range via the matching surface; a key is matched with the keyway of the hub, and is connected with the hub in to a whole by a high intensity bolt; two metal rubber blocks are respectively put into the gear ring holes on the two sides of the key. The metal rubber flexible radials gear is capable of suppressing the high frequency component of noise, and is in particular to have a good effect of dumping vibration and reducing noise. In addition, the invention is capable of proofing oil, resisting high temperature and corrosion like the common metals, therefore the using life of the metal rubber flexible radials gear is far longer than the common flexible radials gear.

Description

(1) Technical field: [0001] The invention relates to a metal-rubber flexible web gear, in particular to a gear which can adaptively reduce the impact excitation strength of gear meshing and effectively absorb and dissipate the vibration energy of the gear body. Belongs to the gear unit. (two) background technology: [0002] The meshing impact excitation caused by the elastic deformation of the gear teeth under load is the main source of vibration and noise in the gear transmission system. At present, the vibration and noise reduction design of the gear transmission system is mainly realized through two aspects: one is to control the meshing shock excitation source; Body, etc.) transmission. [0003] In the aspect of controlling the impact excitation of gear tooth meshing, the most widely used method is tooth profile modification technology. This technology artificially corrects the tooth profile of the theoretical involute gear to compensate for the elastic deformation of...
