Abstract
The utility model relates to an improved type ball mill comprising two bearings (1) and a cylinder body (2), wherein hollow shaft heads at both ends of the cylinder body (2) are fixedly supported by the two bearings (1), and supporting devices are arranged outside the cylinder body (2); and the supporting devices are in a single group or a plurality of groups and comprise transmission belts or transmission rings (3), rolling devices (4) and supporting seats (5), wherein the transmission belts or transmission rings (3) are sleeved on the outer circumference of the cylinder body (2), and the rolling devices (4) are engaged with the transmission belts or transmission rings (3) and are fixed by the supporting seats (5). The structure adopts the mode that a plurality of supports are arranged in the length of the cylinder body, which ensures multi-point supporting in the running process of equipment, decreases the bearing capacity at both ends, decreases the fatigue damage of the cylinder body and can ensure the long-time normal running of the equipment.
Description
Technical field
The utility model relates to a kind of ball mill, especially has the ball mill of fixed bearing device, specifically a kind of modified ball mill.
Background technology
Ball mill master tube rotating mechanism generally adopts the two ends hollow shaft head at present, and with the supporting of rolling self-aligning bearing, and the main tube of assurance is pressed the certain orientation rotation.But,, cause phenomenons such as some position cracks, fracture because long-time load running state produces fatigue damage to the axle head connecting portion, thereby cause equipment to run well, cause consequences such as stopping production, and maintenance is also very difficult, the loss that causes can't be estimated.
Summary of the invention
The purpose of this utility model is because long-time load running state produces fatigue damage to the axle head connecting portion at the main tube of ball mill, cause the problem of phenomenons such as some position cracks, fracture, propose a kind of modified ball mill that has the fixed bearing device or have adjusting device.
The technical solution of the utility model is:
A kind of modified ball mill, it comprises two bearings and cylindrical shell, the hollow shaft head at cylindrical shell two ends is characterized in that being provided with some supporting arrangements by the two bearings fixed bearing outside cylindrical shell.
Supporting arrangement of the present utility model is single group or many groups.
Supporting arrangement of the present utility model comprises driving-belt or transmission circle, tourelle and bearing, and described driving-belt or transmission snare are contained on the excircle of cylindrical shell, tourelle and driving-belt or the engagement of transmission circle, and tourelle is fixed by bearing.
The beneficial effects of the utility model:
Product of the present utility model is in order to overcome the problems referred to above, avoid defective to produce, pass through structure of modification, make equipment operation normal, this structure adopts some supportings is set in cylindrical shell length, guarantees multi-point support in the equipment operation process, reduces the bearing capacity of two ends and middle cylinder, thereby reduce fatigue damage, can guarantee the long-time normal operation of equipment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, a kind of modified ball mill, it comprises two bearings 1 and cylindrical shell 2, the hollow shaft head at cylindrical shell 2 two ends is characterized in that outside cylindrical shell 2 supporting arrangement being set by two bearings 1 fixed bearing.
Supporting arrangement of the present utility model is single group or many groups; Supporting arrangement comprises driving-belt or transmission circle 3, tourelle 4 and bearing 5, and described driving-belt or transmission circle 3 are sleeved on the excircle of cylindrical shell 2, and tourelle 4 meshes with driving-belt or transmission circle 3, and tourelle 3 is fixing by bearing 5
This structure adopts some supportings is set in cylindrical shell length, guarantees multi-point support in the equipment operation process, reduces the two ends bearing capacity, reduces the fatigue damage of cylindrical shell, can guarantee the long-time normal operation of equipment.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
