Abstract
The invention relates to a damping structure of a speed reducer, which comprises a machine body and a base, wherein the machine body is arranged above the base, two sides of the machine body are respectively provided with a sealing upper seat, an adjusting gasket is arranged between the sealing upper seats and the machine body, a first floating sealing ring is arranged in each of two sides of the machine body, and a second floating sealing ring is arranged in the base corresponding to the first floating sealing ring. The upper sealing seat is moved upwards or downwards by adjusting the thickness (or increasing or decreasing the quantity) of the adjusting gaskets, so that the end surfaces of the two corresponding floating sealing rings are in contact, when an external force is applied to rotate the machine body, friction damping is generated on the end surfaces of the first floating sealing ring in the machine body and the second floating sealing ring in the base, and if the external force is smaller than the damping, the machine body is still. Through the design of this structure, because of there being frictional damping, so the output shaft can be fixed motionless, just so can not lead to the output shaft to drive the input shaft rotation because of external moment, and then the protection internal device is unlikely to damage.
Description
Technical Field
The invention relates to a damping structure of a speed reducer, and belongs to the technical field of mechanical transmission.
Background
At present, an output back clearance (tooth backlash) of a domestic common speed reducer, particularly a worm and gear speed reducer, is large due to the limitation of processing and structure, and when the speed reducer stops running, an output shaft cannot be fixed under the action of certain external force, so that shaking is generated, and equipment can be damaged.
Disclosure of Invention
The invention aims to: aiming at the problem that the prior art cannot meet the existing requirements, the damping structure of the speed reducer is provided to solve the technical problem.
The technical scheme adopted by the invention is as follows: the damping structure of the speed reducer comprises a machine body and a base, wherein the machine body is arranged above the base, two sides of the machine body are respectively provided with a sealing upper seat, an adjusting gasket is arranged between the sealing upper seats and the machine body, a first floating sealing ring is arranged in each of two sides of the machine body, and a second floating sealing ring is arranged in the base corresponding to the first floating sealing ring.
In the present invention: the upper sealing seat and the adjusting gasket are fixed on the machine body through bolts.
In the present invention: the floating seal ring is directly pressed in the machine body, the floating seal ring II is installed in the base in the same mode, the end faces of the two corresponding floating seal rings I are in contact with the end face of the floating seal ring II, the upper sealing seat is moved up or down by adjusting the thickness of the adjusting gasket (or increasing or decreasing the quantity of the adjusting gasket), the end faces of the two corresponding floating seal rings are in contact, when the machine body rotates due to external force, friction damping is generated on the end faces of the floating seal ring I in the machine body and the floating seal ring II in the base, and if the external force is smaller than the damping, the machine body is still.
The invention has the beneficial effects that:
1. the invention has simple structure and reasonable design, and when the speed reducer stops running, a certain external moment still acts on the output shaft;
2. because the gear side clearance of the gear mechanism in the speed reducer is objective, the structure can eliminate the output shaft shaking caused by the gear side clearance, so that even if the requirement on the gear side clearance is low, bad shaking cannot be generated, the machining precision of the gear and the worm gear is reduced due to the reduction of the requirement on the gear, and the cost is saved;
3. the invention is equivalent to self-locking of an output shaft, and the self-locking is invalid due to tooth surface abrasion, clearance enlargement and vibration of a machine body, and the structure can overcome the defects in the aspect.
Drawings
Fig. 1 is a schematic structural view of the present invention.
In the figure: 1. sealing the upper seat; 2. a first floating seal ring; 3. a base; 4. a bolt; 5. adjusting the gasket; 6. a body; 7. and a second floating seal ring.
Detailed Description
The invention is described in further detail below with reference to the figures and specific embodiments.
As shown in fig. 1, a damping structure of a speed reducer includes a machine body 6 and a base 3, the machine body 6 is disposed above the base 3, sealing upper seats 1 are disposed on two sides of the machine body 6, and an adjusting gasket 5 is disposed between the sealing upper seats 1 and the machine body 6, wherein floating seal rings one 2 are disposed in two sides of the machine body 6, and floating seal rings two 7 are disposed in the base 3 corresponding to the floating seal rings one 2. The upper sealing seat 1 and the adjusting gasket 5 are fixed on the machine body 6 through bolts 4. The first floating seal ring 2 is directly pressed in the machine body 6, the second floating seal ring 7 is arranged in the base 3 in the same way, and the end surfaces of the two corresponding first floating seal rings 2 and the second floating seal rings 7 are in contact. The upper seat 1 is moved upwards or downwards by adjusting the thickness (or increasing or decreasing the number) of the adjusting gaskets 5, so that the end surfaces of the two corresponding floating sealing rings are contacted, when an external force is applied to rotate the machine body 6, friction damping is generated on the end surfaces of the first floating sealing ring 2 in the machine body 6 and the second floating sealing ring 7 in the base 3, and if the external force is smaller than the damping, the machine body 6 is still. In actual operation, when the speed reducer stops running, a certain external moment still acts on the output shaft, and due to the design of the structure, the output shaft can be fixed because of the existence of friction damping, so that the output shaft can not drive the input shaft to rotate due to the external moment, and internal equipment is protected from being damaged; because the gear side clearance of the gear mechanism in the speed reducer is objective, the output shaft shaking caused by the gear side clearance can be eliminated by adopting the structure, and thus, even if the requirement on the gear side clearance is low, bad shaking cannot be generated, so that the machining precision of the gear and the worm gear is reduced due to the reduction of the requirement on the gear, and the cost is saved.
The above description is directed to specific embodiments of the present invention, but the present invention is not limited to the above description. Any equivalent modifications and alterations to this technical solution would be considered within the scope of this invention by those skilled in the art. Accordingly, equivalent changes and modifications made without departing from the spirit and scope of the present invention should be covered by the present invention.
