[0002] In many machines, the connection between the shaft and the gear is realized by a key connection. The key connection is to realize the circumferential locking between the shaft and the parts on the shaft through the key to transmit motion and torque. Its structure is as follows: figure 1 As shown, the corresponding position of shaft 1 and gear 2 is provided with keyway 3, and key 4 is set in keyway 3. Due to the unavoidable error between the size of key 4 and keyway 3 in the manufacturing process, the shaft 1 and gear 2 During the transmission of movement, the key 4 will produce radial and axial movements in the keyway 3, which will cause wear and tear after a period of use, and even damage the keyway 3

Embodiment Construction
[0012] A shaft-to-gear connection mechanism according to the present invention will be further described in detail through specific embodiments below.
[0013] Such as figure 2 As shown, a shaft-to-gear connection mechanism includes a shaft 1 and a gear 2 that cooperate with each other. The side of the connection between the gear 2 and the shaft 1 that is close to the gear 2 is provided with an outer shell that gradually decreases in thickness from top to bottom. Cone ring 3, the outer wall of the outer cone ring 3 is close to the inner wall of the gear 2, and the side close to the shaft 1 is provided with an inner cone ring 4 whose thickness gradually increases from top to bottom, and the outer wall of the inner cone ring 4 is close to the outer wall of the shaft 1, And the outer cone ring 3 and the inner cone ring 4 are closely fitted, the tail of the outer cone ring 3 is matched with the lower end wall of the gear 2, the tail of the inner cone ring 4 is fixedly connected w...

The invention relates to a shaft and gear connecting mechanism which comprises a shaft and a gear. The shaft and the gear are matched with each other, an outer cone ring is arranged on the side, which is close to the gear, of a joint of the gear and the shaft, the thickness of the outer cone ring is gradually reduced from top to bottom, the outer wall of the outer cone ring clings to the inner wall of the gear, an inner cone ring is arranged on the side, which is close to the shaft, of the joint of the gear and the shaft, the thickness of the inner cone ring is gradually increased from top to bottom, the outer wall of the inner cone ring clings to the outer wall of the shaft, and the outer cone ring closely clings to the inner cone ring. The shaft and gear connecting mechanism is applicable to connecting shafts with gears on machinery.
Description
technical field [0001] The invention relates to a connection mechanism between a shaft and a gear. Background technique [0002] In many machines, the connection between the shaft and the gear is realized by a key connection. The key connection is to realize the circumferential locking between the shaft and the parts on the shaft through the key to transmit motion and torque. Its structure is as follows: figure 1 As shown, the corresponding position of shaft 1 and gear 2 is provided with keyway 3, and key 4 is set in keyway 3. Due to the unavoidable error between the size of key 4 and keyway 3 in the manufacturing process, the shaft 1 and gear 2 In the process of transmitting the movement, the key 4 will generate radial and axial movements in the keyway 3, which will cause wear and even damage the keyway 3 after being used for a period of time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a shaft-to-gear conn...
