[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , a new type of bearing heating device, including a base 1, on which a plurality of support rollers 2 are provided. The support rollers 2 are arranged in a circular array. Bearing seats 10 are provided at both ends of the support rollers 2. The bearing seats 10 are arranged on the base 1. A driving component 3 is connected to the end face of the support roller 2. The driving component 3 is used to drive the support roller 2 to rotate clockwise. A heater 6 is provided on the base 1 at a position between two support rollers 2. The heater 6 is slidably matched with the base 1, and a cylinder 9 is provided on the front surface of the heater 6. The other end of the cylinder 9 is connected to the base 1. A heating groove 7 is provided on the front surface of the heater 6, and a heating pipe 8 is provided in the heating groove 7;

[0021] In the present invention, the support roller 2 and the cylinder 9 are provided. The support roller 2 uses the arrangement method of circular array, so that the slewing bearing can be placed, and the slewing bearing is driven to rotate by the driving component 3, so that the slewing bearing can gradually enter and exit the area of the heating groove 7, realizing the purpose of heating the slewing bearing with a small-volume heater 6. The cylinder 9 can push the heater 6 to move, and the heater 6 can be moved away when placing or taking out the slewing bearing, and the heater 6 is moved back during work.

[0022] The driving component 3 includes a driving motor 301, a first bevel gear 302, a second bevel gear 303, a rotating shaft 304 and a chain wheel set 305. The chain wheel set 305 is arranged on the end face of the support roller 2. The rotating shaft 304 is connected to the base 1 through a bearing and is connected to the chain wheel set 305. The second bevel gear 303 is arranged on the end face of the rotating shaft 304. The first bevel gear 302 is arranged on the rotating shaft 304 of the driving motor 301, and the second bevel gear 303 meshes with the first bevel gear 302. The driving motor 301 is fixedly connected to the base 1;

[0023] By setting the first bevel gear 302 and the second bevel gear 303, the first bevel gear 302 can change the direction of the rotational power and transmit it to the second bevel gear 303, and drive the rotating shaft 304 and the chain wheel set 305 to work by using the second bevel gear 303. Moreover, the second bevel gears 303 on both sides of the first bevel gear 302 rotate in opposite directions during rotation, so that the support rollers 2 arranged oppositely rotate in opposite directions, thereby achieving the purpose of rotating the support rollers 2 arranged in an annular array clockwise or counterclockwise.

[0024] Two limit rods 5 are provided at the positions between the support rollers 2 on the base 1. The two limit rods 5 are arranged oppositely and are located outside the outer ring of the bearing.

[0025] By setting the limit rods 5, the slewing bearing can be positioned by using the limit rods 5, so that the center of the slewing bearing is aligned with the centers of the support rollers 2 arranged in an annular array, ensuring that the slewing bearing can rotate smoothly and guaranteeing the normal operation of the heating work.

[0026] An adjusting component 4 is provided under the limit rod 5. The adjusting component 4 is used to adjust the distance between the two limit rods 5. The adjusting component 4 includes a slide rail 401, a bidirectional lead screw 402, a slide block 403 and an adjusting motor 404. The slide rail 401 is arranged on the base 1. The bidirectional lead screw 402 is rotatably connected in the slide rail 401 and is connected to the adjusting motor 404 at one end. The slide block 403 is in threaded cooperation with the bidirectional lead screw 402, and there are two slide blocks 403 which are respectively connected to the two limit rods 5.

[0027] By setting the bidirectional lead screw 402, when the bidirectional lead screw 402 rotates, it will drive the slide blocks 403 on both sides to move towards or away from each other simultaneously, so that the slide blocks 403 drive the limit rods 5 to adjust the distance. Moreover, it is ensured that the center of the distance between the limit rods 5 is always consistent with the centers of the support rollers 2 arranged in an annular array, achieving a positioning effect and being able to adapt to slewing bearings of various sizes at the same time.

[0028] A rubber ring 12 is rotatably connected to the side surface of the limit rod 5, and the rubber ring 12 is in contact with the outer ring of the bearing.

[0029] By setting the rubber ring 12, the rubber ring 12 can make the limit rod 5 contact the slewing bearing flexibly, avoiding wear problems between the two. In addition, the rubber ring 12 is beneficial to the rotational connection with the limit rod 5, so that it can rotate along with the slewing bearing when contacting the slewing bearing, further reducing the wear problem.

[0030] A roller 11 is rotatably connected under the heater 6, and the roller 11 is in contact with the base 1.

[0031] By setting the roller 11, the roller 11 can support the heater 6 and bear the gravity of the heater 6. At the same time, when the heater 6 moves, the roller 11 uses rotation to offset the frictional force with the base 1, making the movement of the heater 6 smoother and reducing the generation of noise.

[0032] Working principle:

[0033] During operation, the cylinder 9 pushes out the heater 6, and the heater 6 slides backward using the roller 11 to place the slewing bearing on the support roller 2. Then, the adjustment motor 404 drives the bidirectional lead screw 402 to rotate, and the bidirectional lead screw 402 drives the slide block 403 to move. The slide block 403 drives the rubber ring 12 to fit with the outer ring of the slewing bearing through the limit rod 5 to position the slewing bearing. Then, the motor drives the second bevel gear 303 to rotate through the first bevel gear 302. The second bevel gear 303 drives the chain wheel set 305 to move through the rotating shaft 304. The chain wheel set 305 drives the support roller 2 to rotate, and the support roller 2 drives the slewing bearing to rotate. Then, the cylinder 9 pulls back the heater 6 so that the heating groove 7 covers the slewing bearing, and then the slewing bearing is heated using the heating tube 8.

[0034] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements, or modifications made based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present invention.
