Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example cannot be used to limit the scope of the invention for illustrating the present invention.
The dedicated deep groove ball bearing shock ring of the compressor of air conditioner of the embodiment of the present invention is socketed on the outer ring of deep groove ball bearing,
To play cushioning effect.The structure of the shock ring includes as shown in Figure 1：It primary dampening assembly 1 and is symmetrically disposed on primary and subtracts
The advanced dampening assembly 2 of 1 two sides of component is shaken, primary dampening assembly 1 and advanced dampening assembly 2 are all formed as ring-shaped and coaxially set
It sets.The annular radius of primary dampening assembly 1 is greater than the annular radius of advanced dampening assembly 2, and the deformation quantity of primary dampening assembly 1
Greater than the semidiameter of the primary dampening assembly 1 and advanced dampening assembly 2, so that when deep groove ball bearing is in primary vibration, only
Cushioning effect is played by primary dampening assembly 1, when deep groove ball bearing is in advanced vibration, by primary dampening assembly 1 and advanced
Dampening assembly 2 plays cushioning effect jointly.
When the operating load of deep groove ball bearing is underload, primary damping is only needed at this time, only by primary dampening assembly 1
Slight deformation occurs and carrys out shock-absorbing；When the operating load of deep groove ball bearing is high load capacity, biggish shape occurs for primary dampening assembly 1
Become, deformation occurs with the primary common shock-absorbing of dampening assembly 1 to meet heavy-duty service demand for advanced dampening assembly 2 at this time.In this way,
By setting primary dampening assembly 1 and advanced dampening assembly 2 for shock ring, the damping effect of deep groove ball bearing can be sufficiently improved
Fruit, for different vibration ranks, the dampening assembly for having different stage plays cushioning effect, and then enhances damping effect.
As shown in Figures 2 to 5, primary dampening assembly 1 includes with elasticity and being formed as cricoid lasso, tool in the lasso
There is cushion chamber.Specifically, which includes internal layer lasso 3, middle layer lasso 4 and outer ferrule 5, and middle layer lasso 4 is located at internal layer
Between lasso 3 and outer ferrule 5, the inside of internal layer lasso 3, middle layer lasso 4 and outer ferrule 5 all has cushion chamber.By interior
The effect of layer lasso 3, middle layer lasso 4 and outer ferrule 5 and three cushion chambers, primary dampening assembly 1 can fully absorb vibration, this
Cushion chamber in embodiment is formed as diamond-shaped cavity 6, i.e. the cross section of cushion chamber is diamond shape, internal layer lasso 3,4 and of middle layer lasso
Outer ferrule 5 is formed as one formula structure, and the diamond-shaped cavity 6 in internal layer lasso 3, middle layer lasso 4 and outer ferrule 5 is in pairs
Angle setting, to improve shock-absorbing effect.
Further, advanced dampening assembly 2 includes outer layer shock absorbing ring 7 and internal layer shock absorbing ring 8, and internal layer shock absorbing ring 8 is formed as
Continuously alternate plum blossom-shaped structure, lug boss abut the inner wall of outer layer shock absorbing ring 7 for concave part and lug boss.Pass through outer layer shock absorbing ring
7 and internal layer shock absorbing ring 8 carry out shock-absorbing jointly, for the ease of adjusting the elasticity of internal layer shock absorbing ring 8, which is also set
It is equipped with and adjusts screw 9, the concave part that screw 9 spirally screws in abutting internal layer shock absorbing ring 8 after outer layer shock absorbing ring 7 is adjusted, so that convex
The portion of rising abuts the inner wall of outer layer shock absorbing ring 7, can be manipulated according to operating load and adjust the position that screw 9 screws in outer layer shock absorbing ring 7
It sets, to guarantee that the elasticity of internal layer shock absorbing ring 8 is in reasonable range, is convenient for abundant shock-absorbing.In the present embodiment, outer layer is subtracted
Shake circle 7 is set as rigid shock absorbing ring, is elastic shock attenuation circle by internal layer shock absorbing ring 8, elastic shock attenuation circle is for improving rigid shock absorbing ring
Deformation quantity, to improve shock-absorbing effect.
As shown in figure 5, the outer ring of the deep groove ball bearing is socketed with above-mentioned subtract the present invention also provides a kind of deep groove ball bearing
Ring is shaken, runs noise to reduce it.
As described above, the present invention is by setting primary dampening assembly and advanced dampening assembly for shock ring, it can be abundant
The damping effect for improving deep groove ball bearing is only subtracted by the performance of primary dampening assembly when the deep groove ball bearing is in primary vibration
Shake effect, when the deep groove ball bearing is in advanced vibration, plays damping by primary dampening assembly and advanced dampening assembly jointly
Effect.The configuration of the present invention is simple, and damping effect is fabulous.
The above is only the preferred embodiment of the present invention, it is noted that those skilled in the art are come
It says, without departing from the technical principles of the invention, several improvements and modifications can also be made, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
