DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1-4 As shown, a double-motor single-output mechanism of a roller machine provided by an embodiment of the utility model includes a frame 1, an active roller 3 and a driven roller 2 are connected to the inside of the frame 1 through bearings, a motor 1 6 and a motor 2 8 are fixed to the top of the frame 1, and an output shaft 13 of the motor 1 6 and the motor 2 8 are respectively fixed with a driving pulley 1 7 and a driving pulley 2 9, a reducer 4 is fixed to the top outer wall of the frame 1, and the reducer 4 includes a shell 11, an input shaft 12 and an output shaft 13 are connected to the inside of the shell 11 through bearings, and both ends of the input shaft 12 extend to the outside of the shell 11 and are fixed with driven pulleys 5, the two driven pulleys 5 are respectively connected to the driving pulley 1 7 and the driving pulley 2 9 through belt transmission, and a coupling 10 is fixed between the output shaft 13 and the active roller 3.

[0022] Specifically, in this embodiment, a frame 1 is included, wherein a driving roller 3 and a driven roller 2 are connected to the inside of the frame 1 through bearings, a motor 1 6 and a motor 2 8 are fixed to the top of the frame 1, and a driving pulley 1 7 and a driving pulley 2 9 are fixed to the output shafts 13 of the motor 1 6 and the motor 2 8, respectively, and a reducer 4 is fixed to the top outer wall of the frame 1, and the reducer 4 includes a housing 11, and an input shaft 12 and an output shaft 13 are connected to the inside of the housing 11 through bearings, and both ends of the input shaft 12 extend to the outside of the housing 11 and are fixed with driven pulleys 5, and the two driven pulleys 5 are respectively located on both sides of the housing 11, and the two driven pulleys 5 are respectively connected to the driving pulley 1 7 and the driving pulley 2 9. Pulley 2 9 is connected by belt drive, so that motor 1 6 and motor 2 8 drive input shaft 12 to rotate together when working. A coupling 10 is fixed between output shaft 13 and active roller 3. When output shaft 13 rotates, it drives active roller 3 to rotate. The coupling 10 can effectively prevent the vibration generated by active roller 3 from being transmitted to the reducer, so that the service life of the reducer is extended. The power generated by the motor is output to a single active roller 3, so that a differential speed is formed between driven roller 2 and active roller 3, so that the stone is in a tumbling state when being crushed, so that the sharp angle formed after the stone is crushed is removed, thereby improving the processing quality of the stone.

[0023] The utility model provides a double-roller machine with a dual-motor single-output mechanism, in which the dual motors consisting of a motor 1 6 and a motor 2 8 drive the input shaft 12 of the reducer 4 to rotate, thereby making the double-roller machine work with greater power, achieving a stronger performance of the double-roller machine, making stone crushing more efficient, and also making the forces at both ends of the input shaft 12 of the reducer 4 achieve a balanced effect, which can effectively extend the service life of the reducer 4.

The diameter of the side gear 16 is much smaller than that of the driven gear 17. When the side gear 16 drives the driven gear 17 to rotate, the torque is increased again. The driven gear is driven to rotate by the tooth column 14 to increase the torque at the first level. The driven gear 17 is driven to rotate by the side gear 16 to increase the torque at the second level. The active roller 3 obtains a greater torque. When in use, lubricating oil is added to the inside of the shell 11 to reduce the wear of the gears inside the shell 11 during meshing transmission.

[0025] In another embodiment provided by the utility model, a delivery pump 18 is fixed to an outer wall of one side of the housing 11, and the delivery pump 18 is located at a low position of the housing 11, and the inlet of the delivery pump 18 is connected to the housing 11, so that the delivery pump 18 can extract the lubricating oil, and a filter housing 19 is fixed to an outer wall of one side of the housing 11, and a filter cartridge 21 is arranged inside the filter housing 19, and a connecting pipe 23 is connected between the outer wall of one side of the filter housing 19 and the outlet of the delivery pump 18, and the delivery pump 18 is used to deliver the lubricating oil to the inside of the filter housing 19, so that the iron filings generated by the gear wear in the lubricating oil of the filter cartridge 21 are filtered, so as to achieve the effect of removing impurities in the lubricating oil, thereby enabling the lubricating oil of the reducer 4 to maintain good lubrication performance, so that the reducer 4 operates more stably; the end of the filter housing 19 away from the housing 11 is connected with a sealing cover 20 by a thread, and the filter cartridge 21 is fixed to the sealing cover 20. After the sealing cover 20 and the filter cartridge 21 are disassembled, the filter cartridge 21 can be pulled out from the inside of the filter housing 19, and the provided sealing cover 20 is threadedly connected to the filter housing 19, so that the filter cartridge 21 can be conveniently taken out and cleaned from the filter housing 19, thereby making it more convenient for the reducer 4 to maintain the filter cartridge 21; a retaining ring 22 is fixed to the end of the filter cartridge 21 away from the sealing cover 20, and the retaining ring 22 is adapted to the filter housing 19, and a sealing ring is fixed to the outer circle of the retaining ring 22, so that the filter cartridges 21 can be sealed with each other, thereby ensuring that the lubricating oil passes through the filter housing 19 for effective filtration.

[0026] Working principle: When in use, the sealing cover 20 is separated from the filter housing 19, and a sufficient amount of lubricating oil is added from the filter housing 19 to the inside of the housing 11, and then the filter cartridge 21 is inserted into the inside of the filter housing 19, and the sealing cover 20 is threadedly connected to the filter housing 19, and then the motor 16 and the motor 28 respectively drive the driving pulley 17 and the driving pulley 29 to rotate, and then the driven pulley 5 and the input shaft 12 are driven to rotate through the belt, and the rotation of the input shaft 12 drives the gear column 14 to rotate, and the rotation of the gear column 14 drives the driven gear 15 and the side gear 16 to rotate, and the rotation of the side gear 16 drives the driven gear 2 17 to rotate, so that the driven gear 2 17 drives the input shaft 12 to rotate. The output shaft 13 rotates, and the output shaft 13 drives the active roller 3 to rotate, so that the stone between the active roller 3 and the driven roller 2 is crushed; when the tooth column 14, the driven gear 15, the side gear 16 and the driven gear 2 17 rotate, they are lubricated by the lubricating oil inside the housing 11, and at the same time, the delivery pump 18 delivers the lubricating oil inside the housing 11 to the inside of the filter housing 19, so that the filter cartridge 21 inside the filter housing 19 filters the iron filings in the lubricating oil, and the filtered lubricating oil flows back from the filter housing 19 to the inside of the housing 11. When it is necessary to clean the filter cartridge 21, the sealing cover 20 is threadedly separated from the filter housing 19, so that the filter cartridge 21 is taken out from the inside of the filter housing 19 for cleaning.
