Abstract
The utility model is related to a kind of good elastic polyurethane shaft couplings of drag-reduction effect, including interior cylinder and outside cylinder made of polyurethane material, interior cylinder is co-axially located in outside cylinder, it is co-axially mounted driven shaft in interior cylinder, outside cylinder outer rim is embedded in driving shaft inner cavity, between interior cylinder outer rim and outside cylinder inner edge, one is uniformly formed with multiple arcs connecting fin；Drag reduction angle is formed between each two arc connecting fin, the top of the horn at drag reduction angle towards outer circle column wall, integrally make with adjacent arc connecting fin respectively by the two-arm at drag reduction angle.This shaft coupling is formed with drag reduction angle between each two arc connecting fin, the top of the horn at drag reduction angle is towards outer circle column wall, the two-arm at drag reduction angle is integrally made with adjacent arc connecting fin respectively, when use, two adjacent arc connecting fins can form direct drag reduction angle and squeeze, after drag reduction angle is squeezed, crush resistance is formed, two axis of opposite mutually movement have good drag-reduction effect.
Description
Technical field
The utility model belongs to drive components field, the good elastic polyurethane shaft coupling of especially a kind of drag-reduction effect.
Background technology
Shaft coupling also known as shaft coupling are to be allowed to common for two axis (driving shaft and driven shaft) coupled in different institutions
Rotation plays linking to transmit the machine components of torque.
The flexible coupling having elastic component can transmit movement and torque；With different degrees of axial, radial, angular
Compensation performance；Also there is different degrees of vibration damping, cushioning effect, the working performance for improving transmission system includes various nonmetallic bullets
Property element flexible coupling and metallic elastic component flexible coupling, the structure of various yielding couplings is different, differs greatly,
Effect in transmission system is also not quite similar.
Utility model content
The purpose of the utility model is to overcome in place of the deficiencies in the prior art, provide a kind of structure novel, elasticity recovery
The good elastic polyurethane shaft coupling of good drag-reduction effect.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of elastic polyurethane shaft coupling that drag-reduction effect is good, including interior cylinder and outside cylinder made of polyurethane material,
Interior cylinder is co-axially located in outside cylinder, and driven shaft is co-axially mounted in interior cylinder, and outside cylinder outer rim is embedded in driving shaft inner cavity,
Between interior cylinder outer rim and outside cylinder inner edge, one is uniformly formed with multiple arcs connecting fin；
Be formed with drag reduction angle between each two arc connecting fin, the top of the horn at drag reduction angle towards outer circle column wall, drag reduction angle
Two-arm is integrally made with adjacent arc connecting fin respectively.
Moreover, the orientation angle of all connecting fins is identical.
The advantages of the utility model and good effect are：
There are two spaced concentric circles for the good elastic polyurethane shaft coupling tool of drag-reduction effect provided by the utility model
Column is integrally evenly distributed with arc connecting fin between two concentric columns, and the orientation angle of all connecting fins is identical, when in interior cylinder
When driven shaft stops, it is capable of providing good buffer stop.
The good elastic polyurethane shaft coupling of drag-reduction effect provided by the utility model is made between each two arc connecting fin
Have a drag reduction angle, the top of the horn at drag reduction angle towards outer circle column wall, the two-arm at drag reduction angle respectively with adjacent one system of arc connecting fin
Go out, squeezed in use, two adjacent arc connecting fins can be formed direct drag reduction angle, after drag reduction angle is squeezed, is formed
Two axis of crush resistance, opposite mutually movement have good drag-reduction effect.
Description of the drawings
Fig. 1 is the dimensional structure diagram of the utility model.
Fig. 2 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings and by specific embodiment, and following embodiment is only retouched
The property stated, it is not restrictive, protection scope of this utility model cannot be limited by this.
A kind of elastic polyurethane shaft coupling that drag-reduction effect is good, including interior cylinder 3 and outside cylinder made of polyurethane material
1, interior cylinder is co-axially located in outside cylinder, and driven shaft is co-axially mounted in interior cylinder, and outside cylinder outer rim is embedded in driving shaft inner cavity,
Between interior cylinder outer rim and outside cylinder inner edge, one is uniformly formed with multiple arcs connecting fin 2, the orientation angle of all connecting fins
It is identical.
Be formed with drag reduction angle 4 between each two arc connecting fin, the top of the horn at drag reduction angle towards outer circle column wall, drag reduction angle
Two-arm is integrally made with adjacent arc connecting fin respectively, in use, two adjacent arc connecting fins can be to direct drag reduction
Angle, which is formed, to be squeezed, and after drag reduction angle is squeezed, forms crush resistance, two axis of opposite mutually movement have good drag-reduction effect.
There are two spaced concentric columns for elastic polyurethane shaft coupling tool provided by the utility model, with one heart at two
Arc connecting fin is integrally evenly distributed between cylinder, the orientation angle of all connecting fins is identical, when the driven shaft in interior cylinder stops,
It is capable of providing good buffer deceleration effect.
