Description

Technical Field

[0001] The utility model relates to the technical field of shaft sleeves, in particular to a special shaft sleeve for impact-resistant compressors. Background Art

[0002] Referring to the patent document with application number "CN202220806087.1" and titled "An impact-resistant sleeve structure for a screw compressor", this patent document uses an impact-resistant sleeve structure to store lubricating oil in an oil storage chamber, and the extrusion plate in the oil storage chamber continuously squeezes the oil storage cotton under the action of centrifugal force, and squeezes the lubricating oil into the impact-resistant sleeve body for continuous lubrication, which is beneficial to extend the service life of the equipment.

[0003] In the prior art, the impact resistance of the sleeve is achieved through an oil storage cavity and a rubber layer. Although the oil inside the oil storage cavity can continuously increase the lubrication effect, the effect on the impact force is minimal. A large impact force may cause the oil storage cylinder of the sleeve to rupture, and the impact force cannot be resolved, resulting in the sleeve being unable to be used normally, thereby reducing the service life of the sleeve.

[0004] For this reason, we have designed a special sleeve for shock-resistant compressors. Utility Model Content

[0012] Preferably, the rubber column is fixedly connected to the lifting shaft through a fixing buckle, and the lifting shaft is slidably connected to the lifting rod.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model adopts the arrangement of the hydraulic shaft and the compression spring, so that when the first sleeve is subjected to the impact force brought by the second sleeve, the impact force can be dispersed through the resistance of the hydraulic shaft and the compression spring, so that when the second sleeve is subjected to the impact, the minimum force can be transmitted to the first sleeve, so as to ensure the service life of both, and at the same time improve the dispersion of the impact force, and extend the use effect of the first sleeve and the second sleeve.

[0021] Reference Figure 1-Figure 4A special sleeve for an impact-resistant compressor includes a first sleeve 1 and a second sleeve 2, both of which are special sleeves for compressors in the prior art. A slide groove 9 is opened at the tail end of the first sleeve 1, and the tail end is the contact surface with the second sleeve 2. The slide groove 9 is opened along the arc edge of the first sleeve 1, and the pressure groove is a contact groove for the compressor to impact the second sleeve 2.

[0022] A first sleeve 3 for connecting to the second sleeve 2 is symmetrically provided on the first sleeve 1. The first sleeve 3 is used to protect a portion of the hydraulic shaft 6 and the trigger body 8 to prevent external factors from affecting the normal operation of the two. One end of the first sleeve 3 is fixedly connected to the first sleeve 1, and the first sleeve 3 is fixedly connected to the second sleeve 2 through the second sleeve 4. The diameter of the second sleeve 4 is slightly larger than that of the first sleeve 3, and one end is fixed to the end face of the second sleeve 2, and the second sleeve 4 is adapted to the first sleeve 3. When the second sleeve 2 is subjected to a large impact force, the second sleeve 4 will produce an overlapping effect with the first sleeve 3 according to the size of the impact force to ensure the normal stretching action of the hydraulic shaft 6 and the trigger body 8.

[0023] The first sleeve 1 is provided with a plurality of hydraulic shafts 6 for absorbing the impact of the second sleeve 2. The hydraulic shaft 6 is a prior art, and achieves the effect of damping and deceleration through its own hydraulic characteristics, thereby reducing the impact force of the second sleeve 2. A plurality of circular grooves 5 are provided at one end of the first sleeve 1, and the circular grooves 5 are placement grooves for the hydraulic shafts 6. The depth of the circular grooves 5 depends on the length of the hydraulic shafts 6, and the specific specifications shall be determined according to the length of the first sleeve 1. The diameter of the circular grooves 5 is the same as the inner wall diameter of the first sleeve 3. One end of the hydraulic shaft 6 is fixed in the circular groove 5 by a fastener, and the fastener is a snap-on component. A compression spring 7 for improving the efficiency of the hydraulic shaft 6 is provided in the circular groove 5. The compression spring 7 is arranged around the hydraulic shaft 6, and its length is only two-thirds of the hydraulic shaft 6. The compression spring 7 is mainly used to prevent the second sleeve 2 from directly contacting the first sleeve 1, and at the same time provide resistance to the hydraulic shaft 6 during the extrusion process, thereby improving the efficiency of impact force dispersion.

[0024] A trigger body 8 is provided on the hydraulic shaft 6. The trigger body 8 is equivalent to a component that can react after being touched and has its own sensitivity. A long groove is opened on the hydraulic shaft 6. The long groove is used to accommodate the trigger body 8. The shape of the trigger body 8 is composed of a cylinder and two rectangles, and the long grooves are protruding from the two ends of the rectangles, and the trigger body 8 is adapted to the long groove. One end of the trigger body 8 is against the compression spring 7. By means of the abutment, the compression spring 7 can be quickly squeezed with the movement of the hydraulic shaft 6, forming a resistance trend.

[0025] A plurality of lifting rods 10 matched with the trigger body 8 are arranged in the slide groove 9. The lifting rod 10 is a component that generates a lifting action by contracting the trigger body 8, and the lifting height depends on the setting of the lifting shaft. The slide groove 9 is connected with the circular groove 5, and the maximum effective force of the lifting rod 10 can be achieved only when it is connected. A lifting shaft is arranged on the lifting rod 10, and the lifting shaft is driven by the force exerted on the lifting rod 10, and the lifting shaft and the internal components of the lifting rod 10 are in a compatible state. The two ends of the lifting rod 10 are fixedly connected to the trigger body 8 through a traction rod. The traction rod is a force transmission component between the trigger body 8 and the lifting rod 10, and the traction rod has a rebound characteristic, and a spring is arranged inside it.

[0026] The lifting rod 10 is provided with a plurality of rubber columns 11 for buffering the impact of the second sleeve 2. The rubber columns 11 mainly resist the second sleeve 2 in the impact state and disperse the remaining impact force of the second sleeve 2, thereby achieving the effect of impact resistance. The rubber columns 11 are fixedly connected to the lifting shaft through a fixing buckle, and the lifting shaft is slidably connected to the lifting rod 10, and the lifting shaft slides vertically.

[0027] The working principle of the utility model is as follows: when the second sleeve 2 is subjected to a small impact, the impact force will be directly decomposed by the hydraulic shaft 6 and the compression spring 7, reducing the direct impact of the second sleeve 2 on the first sleeve 1; when the second sleeve 2 is subjected to a large impact force, the trigger body 8 will contract under the action of the impact force, and quickly transfer the force to the lifting rod 10, forcing the lifting shaft to lift upward, and making the rubber column 11 press against the contact surface of the second sleeve 2.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
