Description

Technical Field

[0001] The invention relates to an ice maker, in particular to a reduction box for the ice maker. Background Art

[0002] After the ice maker has finished making ice, the whole block of ice needs to be broken up by a rotating blade head, which is fixed on the output shaft of the reduction motor. The reduction motor of the ice maker consists of a motor and a reduction box. In order to reduce the length of the reduction motor and reduce the size of the ice maker, an L-shaped reduction motor is usually used. The motor of the reduction motor is connected and fixed to the fixed frame in the ice maker. Due to the large load of the ice maker and the blade head deviating from the fixed position of the reduction motor and the fixed frame, the reduction motor is prone to shaking, noisy, and has a short service life when used. Summary of the invention

[0003] The object of the present invention is to provide a reduction box for an ice maker which can make the reduction motor more stably fixed, thereby reducing the noise during use and prolonging the service life.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a reduction gearbox for an ice maker, comprising a case body, a case cover matched with the case body and a reduction gear assembly arranged in the case body, the reduction gear assembly comprising an output shaft, the output shaft extending from the front end surface of the case body, a first bearing chamber for fixing a first bearing is provided in the case cover at a position corresponding to the inner end of the output shaft, the bottom of the first bearing chamber protrudes to the outside of the case cover to form a first boss, the inner end of the output shaft is rotatably supported in the first bearing chamber by the first bearing, the case cover is provided with at least three second bosses around the first boss, the second bosses are higher than the first boss, each of the second bosses is formed with a threaded hole for reducing gearbox installation, and the at least three second bosses are arranged in a ring-shaped manner with the axis of the first boss as the center.

[0005] The second boss of the reduction box of the present invention is used to be fixed with the fixing frame by fixing screws. When the output shaft rotates, the force generated by the collision between the cutter head and the ice cube will be transmitted to the fixing frame through the second boss to reduce the force borne by the reduction box body, so as to avoid the deformation of the reduction box, thereby extending the service life of the reduction box; the fixing point of the second boss of the reduction box and the fixing frame is located at the rear side of the output shaft and is close to the output shaft, so that the fixing stability of the reduction box is better, and the rotation of the output shaft is difficult to drive the reduction box body to shake, so as to reduce the noise of the reduction box of the present invention when it is used. Among them, the second boss is arranged in an annular interval with the first boss as the center, so that the force transmitted by the output shaft to the box body cover can be more evenly distributed to the fixing frame. Among them, a part of the first bearing chamber is located in the first boss, so that the internal space of the reduction box is smaller, so that the box body is smaller, and when the same amount of lubricating oil is added, the lubrication effect of the reduction assembly in the reduction box of the present invention can be better, so as to further reduce the noise of the reduction box of the present invention when it is used. Among them, the fixing point of the fixing frame and the reduction box is located at the L-shaped corner of the entire reduction motor, and the fixing frame does not occupy additional space, which can make the internal structure of the ice maker more compact and smaller.

[0006] Preferably, the second bosses are arranged in a ring shape with the axis of the first boss as the center and at even intervals. The above arrangement enables the force on the box to be more evenly transmitted to the fixing frame, thereby reducing the shaking amplitude of the reduction box, further reducing noise, and extending the service life.

[0007] Preferably, the number of the second bosses is six. The six second bosses are provided to reduce the connection between the reduction box and the fixing frame, thereby reducing the assembly process, and ensuring the connection strength between the reduction box body and the fixing frame, ensuring the fixing stability of the reduction box, and reducing the shaking amplitude of the reduction box.

[0008] Preferably, the height of the second boss is 2-5 times the height of the first boss. The above arrangement makes the structural strength of the second boss higher, the second boss is not easily damaged, and the connection between the second boss and the fixing frame is more stable.

[0009] Preferably, a first reinforcing rib is connected between the side wall of the second boss and the side wall of the first boss. By providing the first reinforcing rib, the second boss is connected to the first boss, so that the force received by the output shaft can be better transmitted to the fixing frame through the first bearing, the first boss and the second boss, so as to further reduce the shaking amplitude and noise of the reduction box.

[0010] Preferably, the height of the first reinforcing rib close to the second boss is greater than the height of the first reinforcing rib close to the first boss, and the reinforcing rib is in a trapezoidal structure or a triangular structure. The height of the first reinforcing rib at the connection with the second boss is greater than the height of the first reinforcing rib at the connection with the first boss, so that the second boss is not easily damaged or cracked, thereby making the connection and fixation between the reduction gearbox and the fixing frame more stable.

[0011] Preferably, the reduction assembly includes an input gear, a linkage gear and an output gear, the input gear sleeve is fixed on the input shaft and meshes with the linkage gear, the linkage gear is fixed to the linkage shaft and meshes with the output gear, the output gear sleeve is fixed on the output shaft, a second bearing chamber for fixing the second bearing is provided in the housing, the bottom of the second bearing chamber protrudes to the outside of the housing to form a third boss, the front end of the linkage shaft is rotatably supported in the second bearing chamber through the second bearing, a third bearing chamber for fixing the third bearing is provided in the housing cover, the bottom of the third bearing chamber protrudes to the outside of the housing cover to form a fourth boss, the rear end of the linkage shaft is rotatably supported in the third bearing chamber through the third bearing, and the second boss is higher than the fourth boss.

[0012] Among them, a part of the second bearing chamber is located in the third boss to make the internal space of the box body smaller, and a part of the third bearing chamber is located in the fourth boss to make the size of the reduction box smaller. When an equal amount of lubricating oil is added, the lubrication effect of the reduction assembly in the reduction box of the present invention can be better, so as to further reduce the noise when the reduction box of the present invention is used.

[0013] Preferably, a plurality of second reinforcing ribs are connected between the side wall of the fourth boss and the end face of the box cover, and the plurality of second reinforcing ribs are evenly spaced and arranged in a ring shape with the axis of the fourth boss as the center. By arranging the second reinforcing ribs, the fixing strength between the fourth boss and the box cover is higher, and at the same time, the force borne by the output shaft can be transmitted to the box cover through the output gear, the linkage gear, and the linkage shaft, and then transmitted to the fixing frame, so as to further reduce the shaking amplitude of the reduction box.

[0014] The invention has the advantages of being able to make the reduction motor more stably fixed, thereby reducing noise during use and extending the service life. BRIEF DESCRIPTION OF THE DRAWINGS
