Detailed Description
In order that the above-recited objects, features and advantages of the present invention will be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, without conflict, the embodiments of the present invention and features in the embodiments may be combined with each other.
As shown in fig. 1, the present invention provides a compressor, in which the wear rate of the roller 2 and the crankshaft 1 is relatively small during operation and the service life is long, and a refrigerating apparatus based on the compressor. The compressor comprises a crankshaft 1, rollers 2 and a sliding limiting part 3, wherein the rollers 2 are matched with the crankshaft 1 to perform compression work; in order to install the sliding limiting part 3, the crankshaft 1 may be provided with an installation cavity 11, where the installation cavity 11 has an opening 111, so that, during the working process of the compressor, along with the rotation of the crankshaft 1, the sliding limiting part 3 can contact with the roller 2 through the opening 111 under the action of centrifugal force, that is, a sliding friction relationship is generated between the sliding limiting part 3 and the roller 2, and under the action of the aforementioned friction force, the roller 2 can be prevented from rotating around the crankshaft 1, thereby reducing the wear degree of the roller 2 and the crankshaft 1, and improving the service life of the compressor. Specifically, the mounting cavity 11 may be formed on the crankshaft 1 by drilling, etc., and the mounting cavity 11 may be a through hole or a blind hole, which is not limited herein. In order to improve the limiting effect, the sliding limiting part 3 can be made of hard materials such as metal, the abrasion rate of the sliding limiting part 3 can be reduced, the specific size and the material selection of the sliding limiting part 3 can be determined according to actual conditions, the centrifugal force of the sliding limiting part 3 can be changed, and different limiting effects can be further generated. Of course, as shown in fig. 1, the compressor further includes components such as a motor 5, a bearing 6, a liquid separator 7, and a cylinder 8, all of which are installed in a housing 9, and the details are omitted here in view of brevity. The axial direction may be the direction a in fig. 1.
In addition, in the design process of the current rotary compressor, in order to prevent the roller 2 from being jammed or to prevent the end face of the roller 2 from being worn during the operation process, the height of the cylinder 8 is generally larger than the height of the roller 2 (the height is the dimension along the axial direction of the crankshaft), so that a set gap exists between the cylinder and the roller. However, due to a certain height difference between the roller 2 and the cylinder 8, the roller 2 inevitably moves in the cylinder 8 along with the compressor, and then impacts the bearings 6 arranged above and below the roller 2, and the compressor with the structure provided by the invention hardly has the problems. Specifically, during the working process of the compressor, along with the rotation of the crankshaft 1, the sliding limiting part 3 is in sliding fit with the roller 2, and sliding friction force exists between the sliding limiting part 3 and the roller 2, when the roller 2 generates a trend of moving along the axial direction, the sliding limiting part 3 can also generate a trend of correspondingly inhibiting the movement of the roller 2, and once the roller 2 generates certain displacement along the axial direction and during the displacement process, interaction force along the axial direction is generated between the sliding limiting part 3 and the roller 2, so that the movement of the roller 2 is limited.
In order to enhance the limiting effect of the sliding limiting portion 3 on the roller 2, it is preferable that the sliding limiting portion 3 extends from the opening 111 along the direction perpendicular to the axial direction, so that during the rotation of the crankshaft 1, the centrifugal force generated by the sliding limiting portion 3 is substantially completely applied to the roller 2, so as to increase the friction force between the sliding limiting portion 3 and the roller 2 in a manner of enhancing the utilization rate of the centrifugal force, thereby enhancing the limiting effect.
In order to further enhance the limiting effect, the friction force between the sliding limiting portion 3 and the roller 2 can be increased by increasing the magnitude of the centrifugal force. Specifically, the installation cavity 11 may be formed on the eccentric portion of the crankshaft 1, and the expansion and contraction direction of the sliding limiting portion 3 (in a normal case, the axial direction of the installation cavity 11 is equivalent Yu An) is overlapped with a straight line where the diameter of the eccentric portion passes through the axis of the installation cavity, and the opening 111 is located at one side far away from the axis of the eccentric portion, so that in the rotation process of the eccentric portion, due to the larger rotation radius of the sliding limiting portion 3, the generated centrifugal force is correspondingly larger, so as to achieve the purpose of improving the limiting effect between the sliding limiting portion 3 and the roller 2.
Since the sliding limiting portion 3 tends to shrink inwards away from the roller 2 after hitting the roller 2, the limiting effect generated between the sliding limiting portion 3 and the roller 2 is very limited only under the action of centrifugal force, and in order to further ensure that a reliable limiting relationship can be formed between the sliding limiting portion 3 and the roller 2, preferably, the compressor provided by the invention further comprises an elastic portion 4, the elastic portion 4 is arranged in the mounting cavity 11, and the elastic portion 4 is abutted against the sliding limiting portion 3, so that the sliding limiting portion 3 has a tendency to be separated from the mounting cavity 11 from the opening 111 during rotation of the crankshaft 1; since the roller 2 is disposed outside the crankshaft 1, the sliding limiting portion 3 is blocked by the roller 2, and the sliding limiting portion 3 is urged to retract into the mounting chamber 11 by the blocking action of the roller 2. By arranging the elastic part 4 in the installation cavity 11, the invention can prevent the sliding limit part 3 from shrinking inwards under the action of the elastic part 4, even if the sliding limit part 3 still shrinks inwards, the elastic part 4 is compressed to generate elasticity, and the sliding limit part 3 can be pushed to contact with the roller 2 under the action of the elasticity, so that a reliable limit relation is formed between the sliding limit part 3 and the roller 2, and the occurrence of the conditions of autorotation, up-down movement and the like of the roller 2 in the working process is prevented. Specifically, the elastic part 4 can be a compression spring, and the elastic part 4 with the structure has the advantages of convenience in material taking, lower cost and better elastic performance. In order to improve the connection reliability between the elastic portion 4 and the sliding limit portion 3, it is preferable that the end surface of the sliding limit portion 3 near the elastic portion 4 be provided in a flat surface so as to improve the reliability when it abuts against the elastic portion 4.
Preferably, during the assembly process of the compressor, the size of the installation cavity 11 and the sliding limiting part 3, or the model of the elastic part 4 can be changed, when the compressor is stopped, the elastic part 4 also has a set initial elastic force, so that the sliding limiting part 3 is pushed to contact with the roller 2 under the action of the elastic force to form a static friction relationship, and once the crankshaft 1 starts to rotate, the sliding limiting part 3 can further lift the friction force with the roller 2 under the action of centrifugal force. More specifically, the magnitude of the initial elastic force of the elastic portion 4 may be set according to the actual situation of the compressor.
Alternatively, a part of the elastic portion 4 may be in a relatively fixed relationship with the crankshaft 1, so that during operation of the compressor, the elastic portion 4 can always provide a certain elastic force for the sliding limiting portion 3, no matter how the sliding limiting portion 3 is operated, so as to ensure that a reliable limiting relationship can be formed between the sliding limiting portion 3 and the roller 2. Specifically, the elastic portion 4 may be fixed to the cavity wall of the installation cavity 11 by means of a snap-fit; or the elastic part 4 can be always in a compressed state in the working process by changing the sizes or structures of the mounting cavity 11, the sliding limiting part 3 and the elastic part 4, and the like, so that the end part of the elastic part 4 far away from the sliding limiting part 3 can be always fixed relative to the mounting cavity 11; alternatively, the end of the elastic portion 4 may be directly fixedly connected to the wall of the mounting cavity 11 by welding, bonding, or the like, which is not limited herein.
In addition, the two opposite ends of the installation cavity 11 may be provided with openings 111, in which case, an elastic portion 4 and a sliding limiting portion 3 may be installed in the installation cavity 11, and a relatively fixed relationship may be formed between the elastic portion 4 and the installation cavity 11; or the elastic part 4 and the installation cavity 11 can be movably connected. Specifically, in the compressor of such a structure, the sliding and limiting parts 3 and 4 installed in the installation cavity 11 can form sliding friction relationship with the roller 2, and in order to further enhance the limiting effect, it is preferable that the sliding and limiting parts 3 be provided on opposite sides of the elastic part 4, respectively, and the structures of the two sliding and limiting parts 3 be identical, in which case, the elastic part 4 need not be fixed on the installation cavity 11, and the two sliding and limiting parts 3 can protrude from the two openings 111, respectively, and form sliding friction relationship with different positions of the roller 2, respectively, thereby further enhancing the limiting effect acting on the roller 2. In addition, in the case that the installation cavity 11 has a bottom structure, the crankshaft 1 (or the eccentric portion) may be provided with a plurality of sliding limiting portions 3, and each of the sliding limiting portions 3 is provided with an elastic portion 4, and the plurality of sliding limiting portions 3 may be uniformly distributed around the axial direction of the crankshaft 1, which may further promote the limiting effect acting on the roller 2.
In order to further improve the effect of the sliding limiting portion 3 in suppressing the play of the roller 2 during the operation thereof, preferably, as shown in fig. 2 and 3, the inner side surface of the roller 2 may be provided with a groove 21, and the sliding limiting portion 3 may be mutually matched with the groove 21, thereby further preventing the roller 2 from moving along the aforementioned axial direction during the operation of the sliding limiting portion 3, and as described above, in the case that the sliding limiting portion 3 is provided with the elastic portion 4, under the action of the elastic portion 4, the sliding limiting portion 3 may be basically ensured to be mutually matched with the groove 21 all the time, so as to further improve the effect of suppressing the play of the roller 2. Considering that the roller 2 inevitably rotates about the crankshaft 1 during movement, it is preferable that, as shown in fig. 3, the groove 21 may be provided on the inner side surface of the roller 2 around the aforementioned axial direction, thereby forming an annular groove 21, which allows the sliding stopper 3 to be always brought into a mating relationship with the groove 21 regardless of the rotation of the roller 2 about the crankshaft 1, preventing the roller 2 from moving in the aforementioned axial direction.
Further, considering that the roller 2 and the crankshaft 1 are both circular structures, and both the roller 2 and the crankshaft 1 rotate during the working process, in order to further improve the connection tightness between the sliding limiting portion 3 and the groove 21, preferably, as shown in fig. 2, one end, in contact with the roller 2, of the sliding limiting portion 3 may be provided with an arc surface 31, and the arc surface 31 may be a circular arc surface, a cylindrical side surface or a spherical surface, which is further beneficial to improving the smoothness of sliding fit between the sliding limiting portion 3 and the roller 2, further reducing the wear rate of the sliding limiting portion 3 and the roller 2, and improving the service life of the sliding limiting portion 3 and the roller 2.
