Abstract
The utility model provides a reducer casing for a bar mill. The reducer casing for the bar mill comprises an upper case body and a lower case body. An input gear shaft and a first output gear shaft are arranged in a joint position of the upper case body and the lower case body. Bearings at one end of the input gear shaft are a pair of conical bearings. A gear is arranged on the first output gear shaft. The input gear shaft and the first output gear shaft are horizontally arranged and are meshed with each other through the gear. A second output gear shaft is arranged at the lower end of the first gear shaft in a parallel mode. The first output gear shaft and the second output gear shaft are mutually meshed. Output ends of the first output gear shaft and the second output gear shaft are respectively provided with a flange. The reducer casing has the advantages that the input gear shaft is in first-level horizontal transmission, the output gear shafts are in first-level vertical parallel transmission, the bearings at one end of the input gear shaft are the conical bearings, four corners of each conical bearing are fixed in a bearing sleeve, bearings at the other end of the input gear shaft are self-aligning bearings, and axial directions of outer diameters of the self-aligning bearings can be adjusted freely so that the centripetal force of the bearings can be overcome. The reducer casing further has the advantages of being simple in structure, convenient to use, good in braking effect, and the like.
Description
Technical field
The utility model belongs to the speed reducer field, especially relates to a kind of speed reducer for bar mill.
Background technique
In the production line of making bar, need to use bar mill that bar is processed, in bar mill, need to use speed reducer that bar mill is braked.In existing technology, the axial force when work of the gear shaft in the speed reducer in the bar mill is larger, has the bad technical problem of braking effect.
Summary of the invention
Problem to be solved in the utility model provides a kind of speed reducer for bar mill, is particluarly suitable for processing in the milling train of bar using.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of speed reducer for bar mill, comprise upper box and lower box, be provided with input gear axle and the first output gear shaft in the junction of described upper box and lower box, the bearing of described input gear axle one end is a pair of conical bearing, its Corner Strapped is in bearing housing, the bearing of the other end is selfaligning bearing, described the first output gear shaft is provided with gear, described input gear axle and described the first output gear shaft are horizontally disposed with and mesh by gear, parallel second output gear shaft that is provided with is respectively equipped with flange on the output terminal of described the first output gear shaft and described the second output gear shaft in the lower end of described the first output gear shaft.
Further, described the first output gear shaft, the second output gear shaft and input gear axle are helical gear shaft, and described gear is helical gear.
Further, described the first output gear shaft and described the second output gear shaft velocity ratio are 1:1.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, the input gear axle is the horizontal transmission of one-level, output gear shaft is up and down parallel drive of one-level, the bearing of input gear axle one end is conical bearing, its Corner Strapped is in bearing housing, the bearing of the other end is selfaligning bearing, but its external diameter axial direction free adjustment can overcome the centripetal force of bearing; Have the advantages such as simple in structure, easy to use, good braking effect.
