Description

Technical Field

[0001] The utility model belongs to the technical field related to vertical mills, in particular to a vertical mill reducer and a bevel gear of a driving system. Background Art

[0002] At present, domestic cement production lines are gradually developing towards scale and large-scale. At the same time, with the continuous improvement of environmental protection requirements, the demand for grinding slag, water slag and steel slag has also increased accordingly. As an important operating equipment for grinding conditions, vertical mills are adapted to the supporting construction needs of large-scale dry cement production lines and slag grinding lines. In order to drive the vertical mill with a lower power motor and reduce the cost of use, complex reducer equipment is used. However, it still has the following disadvantages in actual use:

[0003] The overall dimensions of the reducer equipment matched with the vertical mill are large, and the weight of the equipment is overweight, which makes it difficult to lift, transport, maintain and arrange the space. During the work, more manpower and equipment are required, and the cost is high.

[0004] During the operation of the reducer equipment matched with the vertical mill, after the motor is installed, its output shaft is usually set horizontally. However, when the vertical mill is working, the rotation axis of the grinding disc is perpendicular to the horizontal plane, so a complex transmission structure is required for transmission. During the transmission process, due to the use of multiple transmission structures, the power loss of the motor will be large, affecting the economy of the vertical mill. Utility Model Content

[0005] The purpose of the utility model is to provide a vertical mill reducer and a bevel gear for a drive system. By arranging a grinding disc main body, a fixed seat, a transmission assembly and a synchronous motor, the utility model solves the problems of great difficulty in lifting, transporting, maintaining and spatially arranging the reducer equipment matched with the vertical mill, and the use of multiple transmission structures will cause a large power loss of the motor.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a vertical mill reducer and a bevel gear drive system, comprising a grinding disc body, a fixed seat, a transmission assembly and a synchronous motor. A conical gear ring is fixed on the peripheral side of the grinding disc body, a fixed seat is arranged below the conical gear ring, both sides of the fixed seat and one end away from the grinding disc body are rotatably connected with a rotating plate, a transmission assembly is arranged on the top of the fixed seat, and a synchronous motor is arranged on the side of the fixed seat away from the center of the grinding disc. When working, the grinding disc body is rotated to drive the vertical mill to work, the transmission assembly is supported on it by the fixed seat, the power generated by the synchronous motor is transmitted to the transmission assembly, and under the transmission of the transmission assembly, the conical gear ring is driven to drive the grinding disc body to rotate.

[0008] Furthermore, the lower end of the grinding disc body is rotatably connected to a base, which is supported on the lower end of the grinding disc body and forms a movable support with the grinding disc body and the conical gear ring through the thrust bearing and positioning bearing inside the grinding disc body.

[0009] Furthermore, a fixed triangle plate is fixed to the bottom of the fixed seat, the fixed triangle plate is fixed to the peripheral side of the base, a limiting strip is fixed to the side of the longitudinal center line of the top surface of the fixed seat away from the rotating plate, the fixed seat is fixed to the base through the fixed triangle plate, and the fixed seat limits the position of the support seat thereon through the limiting strip.

[0010] Furthermore, the transmission assembly includes a support seat, which is arranged on the top of the fixed seat, both sides of the support seat and the side away from the grinding wheel body are in contact with the rotating plate, and the side of the support seat close to the grinding wheel body is abutted against the limit bar, and the transmission assembly supports the transmission shaft on the fixed seat through the support seat.

[0011] Furthermore, the transmission assembly also includes a transmission shaft, a half-coupling 1 and a bevel gear. The center of the support seat is connected to a transmission shaft that passes through and rotates along the transverse center line. A bevel gear is fixed to the end of the transmission shaft close to the grinding disc body, and the bevel gear and the bevel gear ring are meshed with each other. A half-coupling 1 is fixed to the end of the transmission shaft away from the bevel gear. After half-coupling 1 transmits the power of half-coupling 2, it drives the transmission shaft to rotate, driving the bevel gear to rotate, and the grinding disc body is driven to rotate through the meshing of the bevel gear and the bevel gear ring.

[0012] Furthermore, a fixed base is fixed at the bottom of the synchronous motor, a driving shaft is fixed at the output end of the synchronous motor, a half-coupling 2 is fixed at the end of the driving shaft away from the synchronous motor, and the half-coupling 1 and the half-coupling 2 are engaged with each other. After the synchronous motor drives the driving shaft to rotate, it drives the half-coupling 2 to rotate, and drives the half-coupling 1 to rotate.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem of great difficulty in lifting, transporting, maintaining and spatially arranging the reducer equipment matched with the vertical mill by arranging a grinding disc main body, a fixed seat and a transmission assembly. When it is necessary to disassemble the transmission assembly on the fixed seat, firstly loosen the half coupling one and the half coupling two, remove the synchronous motor, rotate the rotating plate on the fixed seat, rotate the rotating plate to not contact the support seat, and then push the support seat to separate the bevel gear and the bevel gear ring from each other, completing the disassembly of the transmission assembly. Due to the use of fewer transmission structures, the lifting, transportation, maintenance and spatial arrangement of the reducer equipment matched with the vertical mill are less difficult and convenient to use.

[0015] The utility model solves the problem that the reducer equipment matched with the vertical mill adopts multiple transmission structures for transmission, which will cause a large power loss of the motor, by arranging a fixed seat, a transmission component and a synchronous motor. The power generated by the synchronous motor drives the drive shaft to rotate, and after the half coupling one and the half coupling two are driven, the drive shaft is driven to drive the bevel gear to rotate. The bevel gear and the bevel gear ring are meshed with each other. When the bevel gear rotates, it drives the bevel gear ring to rotate, drives the grinding disc main body to work, and drives the vertical mill to work. When working, the high-speed coupling, right-angle reducer, low-speed coupling and other speed change mechanism components used in the traditional vertical mill reducer are omitted, thereby reducing wear and saving costs.
