Abstract

The utility model relates to a speed reducer field provides a ladle turret speed reducer of steel mill. The bevel gear box is characterized by comprising a box body, wherein a bearing is vertically supported in the box body and is provided with a first intermediate shaft, a second intermediate shaft and an output shaft, the first intermediate shaft is driven by an intermediate gear pair to drive the second intermediate shaft, the second intermediate shaft is driven by an output gear pair to drive the output shaft, a large bevel gear is installed on the first intermediate shaft of the box body, the box body is internally supported by a bearing seat and is provided with the first input shaft and the second input shaft, the first input shaft and the second input shaft are bevel gear shafts, the first input shaft and the second input shaft are meshed with the large bevel gear at the same time, and the first input shaft and the second input shaft are vertically arranged. When the motor of one input shaft fails, the motor of the other input shaft is input, so that the continuous operation of the input rotary table is maintained. Meanwhile, the problem of motor installation caused by the limitation of the space of the rotary table can be avoided; the applicability of deceleration is improved.

Description

Ladle turret speed reducer of steel mill

Technical Field

The utility model relates to a speed reducer field, concretely relates to ladle turret speed reducer of steel mill.

Background

The ladle turret of a steel plant is used for supporting and transferring a ladle, the ladle filled with molten steel is transferred to a steel casting position through the rotation of the ladle turret, and an empty ladle after casting is transferred to a ladle receiving position. The rotation of revolving platform is driven by the speed reducer, because the revolving platform is in the environment of high temperature high vibration, the driving motor of speed reducer breaks down easily, and needs regularly to maintain and overhaul, and the revolving platform needs to shut down, influences production.

Disclosure of Invention

In order to satisfy the requirement of steel mill bale continuous operation, the utility model aims to provide a steel mill bale revolving platform speed reducer of dual input.

In order to achieve the above purpose, the utility model adopts the technical proposal that:

the utility model provides a steel mill bale revolving platform speed reducer, includes the box, has the vertical supporting of bearing to have first jackshaft, second jackshaft and output shaft in the box, first jackshaft is by the vice drive second jackshaft of intermediate gear, and the second jackshaft is by the vice drive output shaft of output gear, install big bevel gear on the first jackshaft of box, there are first input shaft and second input shaft by the bearing frame supporting in the box, first, second input shaft is bevel gear shaft, first, second input shaft simultaneously with big bevel gear meshing, first, second input shaft set up perpendicularly.

Furthermore, the first input shaft is arranged at the left and the right of the box body, and the second input shaft is arranged at the rear side of the box body.

And furthermore, the top of the output shaft extends out of the box body, and two keys are installed at the extending end of the output shaft.

After taking above technical scheme, the beneficial effects of the utility model are that: when the motor of one input shaft fails, the motor of the other input shaft is input, so that the continuous operation of the input rotary table is maintained. Meanwhile, the problem of motor installation caused by the limitation of the space of the rotary table can be avoided; the applicability of deceleration is improved.

Drawings

fig. 2 is a top view of the present invention.

Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings: as shown in the figure, a steel mill bale revolving platform speed reducer, includes the box, and the box comprises last box 1 and lower box 2, and upper and lower box 1,2 are supported by bearing frame 3 within a definite time has first input shaft 4 and second input shaft 5, and is first,

second output shaft

4,5 be horizontal axis and mutually perpendicular, and is first,

second input shaft

4,5 are bevel gear axle, and first input shaft 4 stretches out the end and is located the left side of box, and the end that stretches out of second input shaft 5 is located the rear side of box. A first intermediate shaft 6, a second intermediate shaft 7 and an output shaft 8 are vertically supported in the box body through bearings, a large bevel gear 9 is installed on the first intermediate shaft 6, and the first input shaft 4 and the second input shaft 5 are simultaneously meshed with the large bevel gear 9 to provide double input. The first intermediate shaft 6 drives the second intermediate shaft 7 via an intermediate gear pair 10, and the second intermediate shaft 7 drives the output shaft 8 via an output gear pair 11. The output shaft 8 is output from the top of box, and two keys 12 are installed to the output of output shaft 8 for be connected with the revolving platform, and the phase difference of two keys is 120 degrees.

Because the speed reducer is input by vertical double input shafts, single input can be selected during practical application, and a proper input shaft is selected to be connected with an input motor according to the structure of the rotary table and the installation space of the motor; two input shafts can be selected to be simultaneously connected with input motors, the two motors can be used and standby, and when one motor fails, the other motor is switched to avoid influencing production; one motor can drive the rotary table to rotate forwards, and the other motor can drive the rotary table to rotate backwards, so that the rotary table speed reducer can rotate; and one input shaft can be connected with an input motor, and the other input shaft is connected with a brake device, so that soft brake is provided when the rotary table rotates to a fixed position, the vibration and impact of the rotary table and a bale are reduced, and the safety performance is improved.
