The first-stage intermediate shaft and the input shaft are coaxially arranged in the box body through the short shaft, the width of the box body is not increased under the condition of the same output ratio, the length of the box body is reduced, the size and the weight of the box body are reduced, and the structure is compact.
Description
Technical Field
The utility model relates to a speed reducer field, concretely relates to steel mill ring is speed reducer for cold machine.
Background
The rotary motion transmission device of the ring cooling machine for the steel factory mainly has two forms of friction wheel transmission and pin tooth transmission, and the pin tooth transmission is accurate and convenient to maintain, and the rotary motion transmission device of the small and medium-sized ring cooling machine adopts pin tooth transmission more and more. The rotary transmission of the large-scale circular cooler is single, and the large-scale circular cooler is driven by friction wheels. Since the circulation cooler needs a large torque during operation, the reduction ratio of the reduction gear tends to be 2000 or more. This requires the reduction gear to use multiple intermediate drives to achieve the reduction requirement. When the jackshaft of speed reducer increases, the volume of speed reducer also can increase, causes the field installation and maintains the difficulty.
Disclosure of Invention
In order to solve the defect that the high reduction ratio speed reducer of the ring cooling machine in the prior art is large, the utility model aims to provide a speed reducer for the ring cooling machine of a steel mill with compact structure.
In order to achieve the above purpose, the utility model adopts the technical proposal that:
speed reducer for steel mill ring cooling machine, including the box, the box comprises last box and lower box, goes up the box and installs input shaft, multistage jackshaft and output shaft down between the box, input shaft, multistage jackshaft and output shaft are supported in the box by the bearing, including four jackshafts, the input shaft is installed between first jackshaft and third jackshaft, and second jackshaft and the coaxial setting of input shaft, by input gear pair transmission between input shaft and the first jackshaft, by first transmission gear pair transmission between first jackshaft and the second jackshaft, by second transmission gear pair transmission between second jackshaft and the third jackshaft, by third transmission gear pair transmission between third jackshaft and the fourth jackshaft, by output gear pair transmission between fourth jackshaft and the output shaft.
Furthermore, one end of the input shaft and one end of the second intermediate shaft are respectively supported in bearing holes of the front side wall and the rear side wall of the box body through bearings, and the other end of the input shaft and the other end of the second intermediate shaft are respectively supported in bearing holes of a supporting wall in the middle of the box body through bearings.
Further, the extending ends of the input shaft and the output shaft are positioned on the same side of the box body.
Furthermore, the top of lower box is equipped with the oil groove of each dead eye of round series connection, the oil groove is connected the lubricating oil import.
After taking above technical scheme, the beneficial effects of the utility model are that: the first-stage intermediate shaft and the input shaft are coaxially arranged in the box body through the short shaft, the width of the box body is not increased under the condition of the same output ratio, the length of the box body is reduced, the size and the weight of the box body are reduced, and the structure is compact.

fig. 2 is a cross-sectional 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, the speed reducer for the ring cooling machine in the steel mill comprises a box body consisting of an upper box body 1 and a lower box body 2, wherein an input shaft 3, a four-stage intermediate shaft and an output shaft 4 are arranged between the upper box body 1 and the lower box body 2, the shafts are parallel and coplanar, two ends of each shaft are respectively supported by bearings, and the bearings are arranged in bearing holes between the upper box body 1 and the lower box body 2. In order to lubricate the bearing, a circle of lubricating oil groove 5 which is connected with each bearing hole in series is processed on the top surface box wall of the lower box body, and the oil groove 5 is connected with at least one oil inlet 6. The input shaft 3 is arranged between the first intermediate shaft 7 and the third intermediate shaft 9, the second intermediate shaft 8 and the input shaft 3 are short shafts and are coaxially arranged, one end of the input shaft 3 and one end of the second intermediate shaft 8 are respectively supported in bearing holes in the front side wall and the rear side wall of the box body through bearings, and the other end of the input shaft 3 and the other end of the second intermediate shaft are respectively supported in bearing holes in a supporting wall 10 in the middle of the box body through bearings. The protruding ends of the input shaft 3 and the output shaft 4 are positioned on the same side of the box body. And an end cover and a sealing element are respectively arranged on the outer side of the bearing hole corresponding to each shaft.
An input gear pair is used for transmission 11 between the input shaft 3 and the first intermediate shaft 7, a first transmission gear pair is used for transmission 12 between the first intermediate shaft 7 and the second intermediate shaft 8, a second transmission gear pair is used for transmission 13 between the second intermediate shaft 8 and the third intermediate shaft 9, a third transmission gear pair 15 is used for transmission between the third intermediate shaft 9 and the fourth intermediate shaft 14, and an output gear pair 16 is used for transmission between the fourth intermediate shaft 14 and the output shaft 4.
