Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a suspension conveyor, in particular to a driving gear assembly for a suspension conveyor. Background Art

[0002] The gear suspension conveyor is a commonly used continuous conveying device and is widely used in various industrial fields for continuously conveying finished articles and bulk materials in a factory or on an assembly line.

[0003] An existing conveyor such as a gear transmission line (application number: CN201721722487.X) disclosed in a Chinese patent includes a bottom plate, a motor, a bevel gear box, a vertical frame, a transmission shaft and a transmission rail. The motor, the bevel gear box, the transmission shaft and the vertical frame are fixed on the floor. The bevel gear box, the transmission rail and the transmission shaft are located inside the vertical frame. A transmission chain sprocket is provided on one side of the bevel gear box. A transmission spur gear is provided at the end of the bevel gear box. A driving chain sprocket is provided at the end of the motor. A transmission chain sprocket and a clamping tooth disc are fixed at the upper end of the transmission shaft. The transmission chain sprocket is located above the clamping gear. A transmission spur gear disc is fixed at the lower end of the transmission shaft. The transmission chain sprocket is connected and driven to the driving chain sprocket through a chain. The transmission spur gear meshes with the transmission spur gear disc. A chain belt meshing with the transmission chain sprocket is provided on the transmission rail. A plurality of hooks are evenly arranged below the chain belt. When the hook turns into the transmission chain sprocket, it just gets stuck in the disc tooth gap of the clamping tooth disc.

[0004] In the above-mentioned transmission line, the transmission shaft is vertically arranged. During actual installation, there are relative position accuracy requirements for the gears and the transmission rail arranged on the transmission shaft. Limited by the influence of installation and processing accuracy, when there is a position installation deviation between the transmission rail and the above-mentioned gears, it is necessary to adjust the position height of the entire transmission rail, which is rather inconvenient. Summary of the Utility Model

[0005] The purpose of the present utility model is to address the above problems existing in the prior art and propose a driving gear assembly for a suspension conveyor that is conducive to the assembly of the suspension conveyor.

[0006] The purpose of the present utility model can be achieved by the following technical solutions: The driving gear assembly for a suspension conveyor includes a vertically arranged long shaft and a driving gear sleeved and fixed on the long shaft. It is characterized in that a short shaft is coaxially arranged above the long shaft, and a driven gear is integrally formed on the outer wall of the short shaft. A connecting column is vertically formed on the top surface of the long shaft, and a slot is correspondingly provided on the short shaft. The connecting column is inserted into the slot and the two are connected by a spline. A lower flange is formed on the outer wall of the upper end of the long shaft, and a circle of lower threaded holes is provided on the lower flange. An upper flange is formed on the outer wall of the short shaft, and a circle of upper threaded holes is provided on the upper flange. The number of the upper threaded holes and the lower threaded holes is the same, and the correspondingly positioned upper threaded holes and lower threaded holes are screwed with the same screw.

[0007] The connecting column and the slot are connected by spline fit, and the long shaft and the short shaft are detachably fixed by the cooperation of the upper flange, the lower flange and the screws. On the premise of ensuring that the long shaft and the short shaft are fixedly connected with high coaxiality, after unscrewing the screws, the short shaft can axially slide relative to the long shaft to finely adjust the position of the driven gear, thereby compensating for the installation position deviation of the driven gear and facilitating the assembly of the suspension conveyor.

[0008] In the above-mentioned drive gear assembly for a suspension conveyor, a connecting cavity matching the upper end of the long shaft is provided on the bottom wall of the short shaft. The axis of the connecting cavity is vertically arranged, and the above-mentioned slot is arranged on the bottom wall of the connecting cavity. The upper end of the long shaft is inserted into the connecting cavity. The upper end of the long shaft is inserted into the connecting cavity to close the orifice of the connecting cavity, so that the connection position of the slot and the connecting column is in a relatively closed space, reducing the influence of the outside on the connection of the short shaft and the long shaft and ensuring the stable operation of the drive gear assembly.

[0009] In the above-mentioned drive gear assembly for a suspension conveyor, an annular groove is formed on the outer wall of the upper end of the long shaft, and an O-ring is arranged in the annular groove, and the outer peripheral surface of the O-ring is pressed against the inner wall of the connecting cavity. Under the action of the O-ring, the strength of closing the orifice of the connecting cavity is enhanced, and the structural stability of the drive gear assembly is further ensured.

[0010] In the above-mentioned drive gear assembly for a suspension conveyor, a triangular reinforcing rib is formed between the top surface of the upper flange and the outer wall of the lower end of the short shaft to enhance the strength of the upper flange and the lower end of the short shaft at the same time, making the structure of the drive gear assembly more stable.

[0011] In the above-mentioned drive gear assembly for a suspension conveyor, a tapered guiding surface is formed on the outer wall of the upper end of the long shaft. The guiding surface is above the above-mentioned annular groove, the diameter of the guiding surface gradually increases from top to bottom, and the guiding surface extends to the top surface position of the long shaft. The setting of the guiding surface is used for guiding the insertion of the long shaft and facilitating assembly.

[0012] In the above-mentioned drive gear assembly for a suspension conveyor, the short shaft and the driven gear are integrally cast.

[0013] Compared with the prior art, the drive gear assembly for a suspension conveyor of the present invention has the following advantages:

[0014] 1. The connecting column and the slot are connected by spline fit, and the long shaft and the short shaft are detachably fixed by the cooperation of the upper flange, the lower flange and the screws. On the premise of ensuring that the long shaft and the short shaft are fixedly connected with high coaxiality, after unscrewing the screws, the short shaft can axially slide relative to the long shaft to finely adjust the position of the driven gear, thereby compensating for the installation position deviation of the driven gear and facilitating the assembly of the suspension conveyor.

[0015] 2. The upper end of the long shaft is inserted into the connection cavity, and under the action of the O-ring, the orifice of the connection cavity is sealed, so that the connection position of the slot and the connection column is in a relatively enclosed space, reducing the influence of the outside on the connection of the short shaft and the long shaft, and ensuring the stable operation of the drive gear assembly.

[0020] The following are specific embodiments of the present invention and in combination with the attached drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0021] As Figure 1 and Figure 2 shown, the drive gear assembly for this suspension conveyor includes a vertically arranged long shaft 1 and a driving gear 2 sleeved and fixed on the long shaft 1.

[0022] Among them,

[0023] As Figure 2 and Figure 3 shown, a short shaft 3 is also coaxially arranged above the long shaft 1, and at this time the short shaft 3 is vertically arranged. A driven gear 3a is integrally formed on the outer wall of the short shaft 3, and the driven gear 3a and the short shaft 3 are coaxially arranged. As Figure 1 shown, a connection column 1a is vertically formed on the top surface of the long shaft 1, and the connection column 1a and the long shaft 1 are coaxially arranged. A slot 3b is correspondingly provided on the short shaft 3, and the connection column 1a is inserted into the slot 3b and the two are connected by a spline, so as to form a high-precision circumferential fit between the short shaft 3 and the long shaft 1. A lower flange 1b is formed on the outer wall of the upper end of the long shaft 1, the lower flange 1b and the long shaft 1 are coaxially arranged, and the lower flange 1b has a circle of lower threaded holes. An upper flange 3c is formed on the outer wall of the short shaft 3, the upper flange 3c and the short shaft 3 are coaxially arranged, and the upper flange 3c has a circle of upper threaded holes. The number of the upper threaded holes and the lower threaded holes is the same, and the same screw 4 is screwed into the corresponding upper threaded hole and lower threaded hole.

[0024] It is set that the connecting column 1a and the slot 3b are connected by spline fit, and the long shaft 1 and the short shaft 3 are detachably fixedly connected through the upper flange 3c, the lower flange 1b and the screw 4. On the premise of ensuring that the long shaft 1 and the short shaft 3 are fixedly connected with high coaxiality, after unscrewing the screw 4, the short shaft 3 can axially slide relative to the long shaft 1 to finely adjust the position of the driven gear 3a, so as to make up for the installation position deviation of the driven gear 3a and facilitate the assembly of the suspension conveyor unit.

[0025] Further explanation: A connecting cavity 3d matching the upper end of the long shaft 1 is provided on the bottom wall of the short shaft 3. The axis of the connecting cavity 3d is vertically arranged, and the above slot 3b is arranged on the bottom wall of the connecting cavity 3d. The upper end of the long shaft 1 is inserted into the connecting cavity 3d. The upper end of the long shaft 1 is inserted into the connecting cavity 3d to close the orifice of the connecting cavity 3d, so that the connection position of the slot 3b and the connecting column 1a is in a relatively closed space, reducing the influence of the outside on the connection between the short shaft 3 and the long shaft 1 and ensuring the stable operation of the drive gear assembly. Preferably, an annular groove is formed on the outer wall of the upper end of the long shaft 1, and the annular groove is coaxially arranged with the long shaft 1. An O-ring 5 is arranged in the annular groove, and the outer peripheral surface of the O-ring 5 is pressed against the inner wall of the connecting cavity 3d. Under the action of the O-ring 5, the strength of closing the orifice of the connecting cavity 3d is enhanced, and the structural stability of the drive gear assembly is further ensured.

[0026] As Figure 2 and Figure 3 shown, a triangular reinforcing rib 3e is formed between the top surface of the upper flange 3c and the outer wall of the lower end of the short shaft 3 to enhance the strength of both the upper flange 3c and the lower end of the short shaft 3 at the same time, making the structure of the drive gear assembly more stable. A tapered guiding surface 1c is formed on the outer wall of the upper end of the long shaft 1. The guiding surface 1c is above the annular groove, and the diameter of the guiding surface 1c gradually increases from top to bottom, and the guiding surface 1c extends to the top surface position of the long shaft 1. The setting of the guiding surface 1c is used for guiding the insertion of the long shaft 1 and facilitating the assembly.

[0027] In the actual product, the short shaft 3 and the driven gear 3a are integrally cast.

[0028] The specific embodiments described herein are only illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
