Description

Technical Field

[0001] This utility model relates to the field of electric roller technology, specifically to an oil-cooled electric roller with a brake. Background Technology

[0002] An electric roller conveyor is a new type of drive device that integrates the motor and reducer inside the roller. It is mainly used in stationary and mobile belt conveyors, replacing traditional separate drive devices where the motor and reducer are located outside the drive roller. Electric roller conveyors offer numerous advantages, including compact structure, high transmission efficiency, low noise, long service life, smooth operation, reliable performance, good sealing, small footprint, and easy installation. They are suitable for operation in various harsh environments. Oil-cooled electric roller conveyors utilize oil cooling technology, using circulating cooling oil to remove heat generated by the motor and gears, thus achieving cooling and lubrication.

[0003] In the prior art, such as the Chinese patent with publication number CN220097578U entitled "An Oil-Cooled Electric Roller for Easy Heat Dissipation," the disclosed technical solution describes a device with a heat-conducting ring on the outer wall of the motor, and multiple mounting plates on the outer wall of the heat-conducting ring. Heat sinks are provided on the side of the mounting plates away from the heat-conducting ring. The use of heat sinks improves the heat dissipation effect of the electric roller on the motor, increasing the continuous operating time of the electric roller. However, during the cooling process, due to the influence of heat sources such as the motor and gears, the cooling oil in the roller may have uneven temperature. This unevenly heated cooling oil can be splashed onto the motor and gears. Different parts of the motor and gears will experience uneven heat dissipation due to the varying temperatures of the cooling oil they come into contact with, thus affecting the overall heat dissipation effect. Utility Model Content

[0004] This utility model provides an oil-cooled electric roller with a brake to solve the above problems.

[0005] This utility model adopts the following technical solution: an oil-cooled electric drum with a brake, comprising a drum body, a motor, a transmission mechanism, a braking mechanism, and a heat dissipation mechanism; a first end cover and a second end cover are fixedly installed at both ends of the drum body, the second end cover having an oil filling port, and a fixed shaft rotatably mounted at the center of the first and second end covers; fixed seats are provided on both sides of the drum body, and the fixed shaft and the fixed seats are fixedly connected; a junction box is fixedly installed on the fixed shaft rotatably mounted at the center of the second end cover; the motor is located in the drum body, and the motor and the drum body are coaxial; a first flange is fixedly installed at the end of the motor near the first end cover, and the first flange is fixedly connected to the fixed shaft; a second flange is fixedly installed at the end of the motor near the second end cover, and the second flange is fixedly connected to the fixed shaft; the first flange is a semi-circular irregular flange; the transmission mechanism is located on the first flange and is used to rotate the drum body; the braking mechanism is located on the fixed shaft and is used to stop the drum body from rotating; the heat dissipation mechanism includes an elastic... The drum is equipped with multiple elastic scraper blades, which are fixedly installed on the inner wall of the drum along its circumference, and both ends of the elastic scraper blades are movable. Two matching rods are fixedly installed at the lower ends of the first and second flanges, respectively. Cooling oil is added to the drum through the filling port. When the electric drum is working, the motor drives the drum to rotate through the transmission mechanism. The drum drives the elastic scraper blades to rotate, and as they rotate, they lift the cooling oil in the drum and pour it onto the motor and transmission mechanism. The cooling oil then falls back to the bottom of the drum, carrying away the heat generated by the motor and transmission mechanism. When the elastic scraper blade rotates and contacts the matching rod, the matching rod causes both ends of the elastic scraper blade to bend. After the elastic scraper blade passes the matching rod, its ends return to their original position and swing under its own elasticity, agitating the cooling oil at the bottom of the drum. This makes the temperature of the cooling oil at the bottom of the drum more uniform and facilitates cooling.

[0006] Furthermore, the transmission mechanism includes a first gear, a rotating shaft, a second gear, a third gear, and an internal gear ring; the first gear is fixedly mounted on the motor output shaft, the rotating shaft is rotatably mounted on the upper end of the first flange, the second gear is fixedly mounted on the rotating shaft, and the second gear meshes with the rotating shaft; the third gear is fixedly mounted on the rotating shaft and is located on the side of the second gear near the first end cover; the internal gear ring is fixedly mounted on the inner wall of the cylinder, and the internal gear ring meshes with the third gear; the motor drives the second gear to rotate through the first gear, the second gear drives the third gear to rotate through the rotating shaft, and finally the third gear drives the cylinder to rotate through the internal gear ring.

[0007] Furthermore, the braking mechanism includes a brake sleeve, a hydraulic telescopic rod, and a brake caliper. The brake sleeve is fixedly installed at the end of the first end cover away from the cylinder, and the brake sleeve and the first end cover are coaxial. The brake sleeve and the fixed shaft are rotatably connected. The hydraulic telescopic rod is located on one side of the first end cover and is fixedly installed on a fixed base. The brake caliper is located below the brake sleeve and is fixedly connected to the upper end of the hydraulic telescopic rod. When the electric drum is working, the brake caliper and the brake sleeve are separated. When the electric drum stops running, the hydraulic telescopic rod drives the brake caliper to move upward so that the brake caliper and the brake sleeve abut against each other, thereby stopping the electric drum from rotating.

[0008] The beneficial effects are: when the elastic scraper blade rotates with the drum, the two ends of the elastic scraper blade swing under its own elasticity through the cooperation of the connecting rod, which agitates the cooling oil at the bottom of the drum, making the temperature of the cooling oil at the bottom of the drum more uniform and conducive to cooling down the cooling oil, thereby improving the heat dissipation efficiency of the motor and gears in the drum.

[0009] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0015] An embodiment of the oil-cooled electric drum with brake of this utility model is as follows: Figures 1 to 4As shown: An oil-cooled electric drum with a brake includes a drum body 100, a motor 200, a transmission mechanism, a braking mechanism, and a cooling mechanism. A first end cover 110 and a second end cover 120 are fixedly installed at both ends of the drum body 100, respectively. An oil filling port 121 is provided on the second end cover 120. A fixed shaft 150 is rotatably mounted at the center of the first end cover 110 and the second end cover 120. Fixed seats 140 are provided on both sides of the drum body 100, and the fixed shaft 150 and the fixed seats 140 are fixedly connected. A junction box 180 is fixedly installed on the fixed shaft 150 rotatably mounted at the center of the second end cover 120. The motor 200 is located on the drum body 100. In the first end cap 110, the motor 200 and the cylinder 100 are coaxial; a first flange 210 is fixedly installed on the end of the motor 200 near the first end cap 110, and the first flange 210 is fixedly connected to the fixed shaft 150; a second flange 220 is fixedly installed on the end of the motor 200 near the second end cap 120, and the second flange 220 is fixedly connected to the fixed shaft 150; the first flange 210 is a semi-circular irregular flange; a transmission mechanism is located on the first flange 210, and the transmission mechanism is used to rotate the cylinder 100; a braking mechanism is located on the fixed shaft 150, and the braking mechanism is used to stop the rotation of the cylinder 100; the heat dissipation mechanism includes... The cylinder 100 is equipped with multiple elastic scraper blades 300, which are fixedly installed circumferentially on the inner wall of the cylinder 100, and both ends of the elastic scraper blades 300 are movable. Two matching rods 310 are fixedly installed at the lower ends of the first flange 210 and the second flange 220, respectively. Cooling oil is added to the cylinder 100 through the oil filling port 121. When the electric drum is working, the motor 200 drives the cylinder 100 to rotate through the transmission mechanism, which in turn drives the elastic scraper blades 300 to rotate. The cooling oil in the cylinder 100 is lifted and poured onto the motor 200 and transmission mechanism. The cooling oil then falls back to the bottom of the cylinder 100, carrying away the heat generated by the motor 200 and transmission mechanism. When the elastic scraper 300 rotates and contacts the mating rod 310, the two ends of the elastic scraper 300 bend under the obstruction of the mating rod 310. After the elastic scraper 300 rotates past the mating rod 310, the two ends of the elastic scraper 300 return to their original position and swing under their own elasticity, stirring the cooling oil at the bottom of the cylinder 100. This makes the temperature of the cooling oil at the bottom of the cylinder 100 more uniform and is conducive to cooling down the cooling oil.

[0016] The transmission mechanism includes a first gear 230, a rotating shaft 240, a second gear 250, a third gear 260, and an internal gear ring 270. The first gear 230 is fixedly mounted on the output shaft of the motor 200, the rotating shaft 240 is rotatably mounted on the upper end of the first flange 210, the second gear 250 is fixedly mounted on the rotating shaft 240, and the second gear 250 meshes with the rotating shaft 240. The third gear 260 is fixedly mounted on the rotating shaft 240 and is located on the side of the second gear 250 near the first end cover 110. The internal gear ring 270 is fixedly mounted on the inner wall of the cylinder 100, and the internal gear ring 270 meshes with the third gear 260. The motor 200 drives the second gear 250 to rotate through the first gear 230, the second gear 250 drives the third gear 260 to rotate through the rotating shaft 240, and finally the third gear 260 drives the cylinder 100 to rotate through the internal gear ring 270.

[0017] The braking mechanism includes a brake sleeve 130, a hydraulic telescopic rod 160, and a brake caliper 170. The brake sleeve 130 is fixedly installed at the end of the first end cover 110 away from the cylinder 100. The brake sleeve 130 and the first end cover 110 are coaxial, and the brake sleeve 130 is rotatably connected to the fixed shaft 150. The hydraulic telescopic rod 160 is located on one side of the first end cover 110 and is fixedly installed on the fixed base 140. The brake caliper 170 is located below the brake sleeve 130 and is fixedly connected to the upper end of the hydraulic telescopic rod 160. When the electric drum is working, the brake caliper 170 and the brake sleeve 130 are separated. When the electric drum stops running, the hydraulic telescopic rod 160 drives the brake caliper 170 to move upward so that the brake caliper 170 and the brake sleeve 130 abut against each other, thereby stopping the electric drum from rotating.

[0018] Based on the above embodiments, the working principle and process of this utility model are as follows: Cooling oil is added to the cylinder 100 through the oil filling port 121; when the electric drum is working, the brake caliper 170 and the brake sleeve 130 are separated, the motor 200 drives the second gear 250 to rotate through the first gear 230, the second gear 250 drives the third gear 260 to rotate through the rotating shaft 240, and finally the third gear 260 drives the cylinder 100 to rotate through the internal gear ring 270;

[0019] The cylinder 100 drives the elastic scraper 300 to rotate. When the elastic scraper 300 rotates, it lifts the cooling oil in the cylinder 100 and pours it onto the motor 200 and the transmission mechanism. Afterward, the cooling oil falls back to the bottom of the cylinder 100, carrying away the heat generated by the motor 200 and the transmission mechanism. When the elastic scraper 300 rotates and contacts the mating rod 310, the two ends of the elastic scraper 300 bend under the obstruction of the mating rod 310. After the elastic scraper 300 rotates past the mating rod 310, the two ends of the elastic scraper 300 return to their original position and swing under their own elasticity, stirring the cooling oil at the bottom of the cylinder 100. This makes the temperature of the cooling oil at the bottom of the cylinder 100 more uniform and is conducive to cooling down the cooling oil.

[0020] When the electric drum stops running, the motor 200 is turned off, and the hydraulic telescopic rod 160 drives the brake caliper 170 to move upward so that the brake caliper 170 and the brake sleeve 130 come into contact, thereby stopping the electric drum from rotating.
