Abstract
The utility model relates to a fan shaft structure with easy dismounting. The utility model comprises a fan shaft. One end of the fan shaft is connected with an air wheel, and the other end of the fan shaft is connected with a belt pulley. The fan shaft is assembled with bearings and bearing seats. Two sides of the bearing are provided with bearing axial positioning devices. One section between the two bearings of the fan shaft is a step shape. The fan shaft which is positioned on one side of the air wheel is assembled with the large bearing, and the fan shaft which is positioned on one side of the belt pulley is assembled with the small bearing. The utility model has advantages that the air wheel is not dismounted, the bearings are conveniently and rapidly changed, the production is not stopped when in maintenance, the time is saved, the labor is saved, the structure is reasonable, and the use is reliable.
Description
The utility model relates to a kind of blower fan structure, particularly a kind of detachable mounted blower fan axle construction.
In industrial production, the general rotor diameter of blower fan commonly used is bigger, also very heavy, and wind wheel dismounting in volute is very inconvenient, after blower fan load facility system, has just more increased the difficulty of wind wheel dismounting.Conventional blower fan axle is bearing on two rolling bearings, and in use bearing often damages easily, if the damage of bearings of close blower fan one end, when needing to change bearing, must earlier wind wheel be decomposed to get off, the bearing that damages could be pulled down then, change new bearing, refill wind wheel.The whole operation process not only wastes time and energy, and needs to stop production, and causes very big loss to production, therefore demands providing a kind of easy-to-dismount blower fan axle construction now urgently, thereby addresses this problem.
The purpose of this utility model provides a kind of easy dismantle type blower fan axle construction, needn't unload wind wheel, can be convenient for changing bearing, does not stop production, and is time saving and energy saving, is easy to apply.
The purpose of this utility model is achieved in that it comprises that an end connects wind wheel, the blower fan axle of the other end connecting belt wheel, assembling bearing and bearing support on the blower fan axle, the bearing both sides are provided with the bearing axial direction positioning device, its technological scheme main points are: one section is step-like between the two bearings of blower fan axle, the blower fan axle is positioned at a side of wind wheel and assembles big bearing, and a side that is positioned at belt pulley is assembled little bearing.
Above-mentioned bearing axial direction positioning device is in the side that the blower fan axle is positioned at wind wheel the thrust convex shoulder to be set, and big bearing one side abuts on the thrust convex shoulder, and assembling location axle sleeve and be screwed nut on the blower fan axle of big bearing opposite side holds macro-axis and is pressed on the thrust convex shoulder.
The utility model has the advantages that: need not pull down wind wheel, can change bearing quickly and easily, not stop production during maintenance, time saving and energy saving, help producing, and rational in infrastructure, use reliable.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
See Fig. 1, concrete structure is as follows: an end connects wind wheel 1, the blower fan axle 2 of the other end connecting belt wheel 13, and it has thrust convex shoulder 3 near wind wheel one side, and big bearing 4 one sides dress leans against on the thrust convex shoulder 3; Big bearing 4 opposite side suit axle sleeves 6,2 on axle sleeve 6 and blower fan axle are equipped with flat key 7, to limit relatively rotating of 2 on axle sleeve 6 and blower fan axle.The outer end of axle sleeve 6 is screwed round nut 9, and lock washer 8 is housed, and big bearing 4 is pressed on the thrust convex shoulder 3.One section 10 is step-like between thread section that is screwed round nut 9 and little bearing 11, and this section is the thrust surface of little bearing 11 near the end of belt pulley one side.Big bearing support 5 and small bearing bracket 12 are fixed on the motor cabinet 14.
The process of changing big bearing 4 is as follows: at first belt pulley 13 is pulled down, pulled down little bearing 11 then, open lock washer 8, back out round nut 9, extract axle sleeve 6, can pull down big bearing 4.Installation process is undertaken by above-mentioned reverse order.
Claims (2)
1, a kind of easy dismantle type blower fan axle construction, it comprises that an end connects wind wheel, the blower fan axle of the other end connecting belt wheel, assembling bearing and bearing support on the blower fan axle, the bearing both sides are provided with the bearing axial direction positioning device, it is characterized in that: one section is step-like between the two bearings of blower fan axle, and the blower fan axle is positioned at a side of wind wheel and assembles big bearing, and a side that is positioned at belt pulley is assembled little bearing.
2, easy dismantle type blower fan axle construction according to claim 1, it is characterized in that: the bearing axial direction positioning device is in the side that the blower fan axle is positioned at wind wheel the thrust convex shoulder to be set, big bearing one side abuts on the thrust convex shoulder, and assembling is located axle sleeve and is screwed nut on the blower fan axle of big bearing opposite side.
