Description

TECHNICAL FIELD

[0001] The utility model belongs to gear drive technical field, concretely relates to a spring floating mechanism. BACKGROUND

[0002] Gear drive is a kind of way of transmitting power and movement by the mutual engagement of gear teeth, in this process, pinion rotates on the gear, the contact between the two is point contact or line contact, and this contact mode makes gear drive have the characteristics of high efficiency and accuracy.But when considering the elasticity of material, the situation becomes complex.In gear drive, gear will produce elastic deformation due to the force acting on gear, especially the force at the engagement point is larger.Therefore, the deformation is small in most cases and does not affect the normal transmission of gear.But if the material of gear is easy to deform or the force is too large, the elastic deformation will be more obvious.

[0003] Specifically, the following situations may occur: the engagement surface of the gear and the pinion is reduced, and the engagement accuracy is reduced;The pitch of the gear may change after being stressed, which causes the engagement position of the pinion to deviate, further affecting the engagement accuracy;Due to the deformation of the gear, the pinion may produce impact and vibration when engaging with it, which not only aggravates the wear of the gear, but also produces noise and reduces the transmission efficiency.

[0004] In summary, if the gear is easy to deform when the pinion rotates on the gear, it will cause the phenomenon of poor engagement.

[0005] To solve the existing problems, we propose a spring floating mechanism. CONTENT OF THE UTILITY MODEL
