Description

High-precision heavy-duty gear box

Technical Field

The utility model relates to a high accuracy heavily loaded combination gear case, but wide application is on metallurgical equipment such as rolling mill.

Background

The rolling mill is one of the most important devices in the field of metallurgical rolling, and the technical advancement and the use stability of the rolling mill are directly related to the yield and the quality of products in a rolling line. At present, the on-line roll gap adjustment can be realized by a rolling mill and a large-scale cogging mill on a plate strip production line, and other rolling mills cannot be realized, so that the roll gap adjustment in production needs to be stopped, the productivity of the rolling line is influenced, and the labor intensity of workers is increased. The utility model discloses to this problem, combine engineering practice to design a gear box of high accuracy heavy load, this gear box weight matches with traditional rolling mill roll gap adjustment gear box, and it is convenient to maintain, has great meaning to improving productivity, reduction cost of labor.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a high accuracy heavy load gear box can realize the area and carry the adjustment rolling mill roll gap.

In order to achieve the above object, the utility model discloses a high accuracy heavy load gear box, include: the power system is in transmission connection with the first transmission box body through a shaft; the first transmission box body is in transmission connection with the second transmission box body through a clutch; a detection system is arranged on the first transmission box body;

the transmission case body includes: the worm gear is meshed with the gears of the 1 st gear shaft and the second gear shaft through gears; and a detection shaft of the detection system is in transmission connection with the worm shaft.

Wherein, the detection system is an encoder.

Preferably, the worm and gear assemblies are double-enveloping worm and gear pairs.

Preferably, the gear is a modified helical gear.

The utility model discloses this gear box is because used the vice helical gear that shifts of secondary envelope worm gear worm, and its transmission precision is high, bearing capacity is strong, uses and to realize the area and carry the adjustment roll gap on the rolling mill.

Fig. 2 is a schematic structural diagram of a transmission case.

Fig. 3 is a schematic structural diagram of the detection system.

Detailed Description

The invention will be described in further detail with reference to the following drawings and detailed description:

as shown in figure 1, the device comprises a power element 1, a detection system 2, a coupling 3, a clutch 4, a first transmission case 5 and a second transmission case 6.

Wherein, the power element is a hydraulic motor; the hydraulic motor is connected with the worm 51 through a flat key, the worm 51 drives the worm wheel 52 to rotate, and the worm wheel 52 transmits torque to the gear 54 and the gear 55 through the worm wheel shaft 53 to rotate together; and drives the detection system 2 via the gear shaft 56.

Besides the transmission, the worm wheel 12 in the first transmission box body drives the worm in the second box body to rotate through the coupler and the clutch, and the structure of the second transmission box body is the same as that of the first box body, so that the details are not repeated.

And each gear shaft of the two transmission case bodies can output power to drive other transmission systems.

The detection system comprises an encoder 21, as shown in fig. 3, the shaft of the encoder 21 is mounted on an intermediate shaft 23 through a set screw 22; the intermediate shaft 23 is connected with the gear shafts through threads, and the motion conditions of the gear shafts can be monitored in real time due to synchronous motion of the gear shafts.

Therefore, the utility model discloses a transmission box has used the vice and helical gear that shifts of secondary envelope worm gear worm, and its transmission precision is high, bearing capacity is strong, uses and to realize the area and carry the adjustment roll gap on the rolling mill.
