Abstract
The utility model provides a special tool for heating a bearing. The special tool comprises a heating box body, wherein an oil inlet is formed in the upper part of the heating box body, and an oil outlet is formed in the lower part of the heating box body; a main control device is arranged on the heating box body; the special tool is characterized in that a heating pipe is arranged in the heating box body; heat transfer oil is arranged in the position outside the heating pipe; the oil outlet is connected with a filtering pump through an oil delivery pipe; the filtering pump is connected with two cooling fans through the oil delivery pipe; one of the two cooling fans is connected with the oil inlet through the oil delivery pipe; support plates with holes are arranged on the heating pipe. The special tool can heat various types of bearings, and is simple in structure, easy to operate and high in safety.
Description
Technical field
The utility model belongs to technical field of wind power generating equipment, relates in particular to a kind of for heating the specific purpose tool of bearing.
Background technology
During bearing assemble, if the fit system of bearing inner race and axle journal is interference fit, generally need the heating bearing, during general bearing heating, temperature need to be more than 100 ℃, because temperature is higher, bring trouble with regard to the operation of giving the workman, also increased the danger of operation.Existing bearing heating mode generally adopts Electromagnetic Heating or heats with fire is roasting, the shortcoming of Electromagnetic Heating is, Electromagnetic Heating generally can only heat the bearing of medium and small model, oversize bearing, can not use Electromagnetic Heating, Electromagnetic Heating easily changes the material of bearing, causes the mechanical property of bearing to change, reduced the life-span of bearing, and danger is higher; By the shortcoming of the roasting heating of fire, be, directly roasting with fire, there is no corresponding safeguard procedures, danger is very high.
Summary of the invention
The utility model provides a kind of for heating the specific purpose tool of bearing in order to solve the problem in background technology.
The technical solution of the utility model is achieved in that a kind of for heating the specific purpose tool of bearing, comprise the heating casing, heating casing top is provided with oil-in, oil-out is arranged at bottom, and the heating casing is provided with master control set, it is characterized in that heating in casing being provided with heating tube, heating tube is provided with conduction oil outward, oil-out is connected with filter pump by petroleum pipeline, and filter pump is connected with two cooling fans by petroleum pipeline, and cooling fan is connected with oil-in by petroleum pipeline;
Be provided with gripper shoe with holes above heating tube.
The beneficial effects of the utility model are: the utility model can heat the bearing of Multiple Type, simple in structure, and easy operating is safe.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Part explanation: 1, filter pump, 2, oil-out, 3, cooling fan, 4, cooling fan, 5, petroleum pipeline, 6, master control set, 7, oil-in, 8, the heating casing, 9, heating tube, 10, conduction oil, 11, gripper shoe.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described: a kind of for heating the specific purpose tool of bearing, comprise heating casing 8, heating casing 8 tops are provided with oil-in 7, oil-out 2 is arranged at bottom, heating casing 8 is provided with master control set 6, be provided with heating tube 9 in heating casing 8, the outer conduction oil 10 that is provided with of heating tube 9, be provided with gripper shoe with holes 11 above heating tube 9, the effect of gripper shoe 11 is for fear of bearing, heating tube 9 to be damaged by pressure, gripper shoe 11 is set, can protect heating tube 9, can make again 10 circulations of the upper and lower conduction oil of gripper shoe 11, oil-out 2 is connected with filter pump 1 by petroleum pipeline, filter pump 1 is connected with cooling fan 4 with cooling fan 3 by petroleum pipeline, cooling fan 4 is connected with oil-in 7 by petroleum pipeline 5.
When the temperature of conduction oil 40 ℃ of left and right, bearing is put into to heating casing 8, when the temperature of conduction oil reaches 110 ℃, keep this temperature, after a while, after bearing heating completes, bearing is taken out, carry out assembly manipulation, because the temperature of 8 li conduction oils 10 of heating casing is very high, the temperature of conduction oil could continue the next bearing of heating after need to be lowered, at this moment the conduction oil 10 that heats 8 li of casings flows out from oil-out 2, by filter pump 1, filter out the impurity in conduction oil, conduction oil continues by two cooling fans, the temperature of conduction oil is reduced, by oil-in 7, flow in heating casing 8 again, when the temperature of 8 li conduction oils 10 of heating casing is reduced to 40 ℃ of left and right, filter pump 1 and cooling fan quit work, the bearing that need to heat the next one is put into the 8 continuation heating of heating casing, the temperature of whole process is controlled and is realized by master control set 6, if the bearing size of heating is less, can once heat a plurality of bearings.
