Abstract
The invention provides a bearing pedestal for a cooling fan. A transmission shaft (5) is inserted into a bearing pedestal body (2), and a rolling bearing (7) capable of resisting axial thrust is arranged between the transmission shaft (5) and the bearing pedestal body (2); a stop washer (9) is arranged at the input end of the transmission shaft (5); the end surface of the input end of the bearing pedestal body (2) is directly fixed on a power unit (1) by which the bearing pedestal body (2) is driven; the input end of the transmission shaft (5) is connected with the driving shaft of the power unit (1), by which the transmission shaft (5) is driven; and the output end of the transmission shaft (5) is connected with a cooling fan via a mounting seat (6) for the cooling fan. The invention has the following advantages: the cooling fan can rotate stably and smoothly, while the interaction of the axial force between the cooling fan and the power unit driving the cooling fan can be avoided in the operation, thus improving the operating reliability and service life of the cooling fan and the power unit.
Description
Technical field
The present invention relates to the bearing pedestal for cooling fan that a kind of cooling fan is connected with driver part, relate to a kind of bearing pedestal for cooling fan that can reduce the cooling fan axial force preferably specifically.
Background technique
Cooling fan and the power unit that drives it, for example cooling fan and oil hydraulic motor or motor adopt directly to connect usually.When this connecting means was worked, the axial force that causes cooling fan itself to produce can impact the power unit that drives it, and its functional reliability and working life are descended; When the same power unit that drives cooling fan was worked, the axial force that itself produces also had influence on the functional reliability and the working life of cooling fan.
Summary of the invention
Technical problem to be solved by this invention provides a kind of bearing pedestal for cooling fan, as the connection set of cooling fan with the power unit that drives it.Be sleeved on the rolling bearing that can resist end thrust on the transmission shaft, make transmission shaft can play the effect of isolation from the axial force of the live axle of cooling fan and its power unit of driving.
This bearing pedestal for cooling fan that is connected with the power unit that drives it as cooling fan, transmission shaft inserts in the bearing seat, be provided with the rolling bearing that can resist end thrust between the two, the input end of transmission shaft is provided with lock washer, the input end end face of bearing seat directly is fixed on the power unit body that drives it, the input end of transmission shaft is connected with the live axle of the power unit that drives it, and the output terminal of transmission shaft is connected with cooling fan by the cooling fan fitting seat.
The input end of transmission shaft is that key is connected with the live axle of the power unit that drives it.
The input end end face of bearing seat closely contacts with the power unit body end face that drives it, and the surface of contact sealing leaks outside to prevent the lubricant oil in the oil pocket.
Transmission shaft is a diminished shaft, is sleeved between two rolling bearing inner rings on the transmission shaft to locate with positioning ring.
Transmission shaft is positioned in the bearing seat, is provided with the rolling bearing that can resist end thrust between the two and makes transmission shaft can play the effect of isolation from the axial force of the live axle of cooling fan and its power unit of driving.
Be provided with oil leab in bearing seat, oil leab is communicated with lubricating cup, and lubricant oil enters oil leab through lubricating cup, lubricated rolling bearing.
The input end end face of bearing seat closely contacts with the power unit body end face that drives it, the surface of contact sealing.To prevent that the lubricant oil in the oil pocket from leaking outside.
In order to prevent that lubricant oil output terminal direction to bearing seat in the oil pocket from spilling, on the output terminal end face of bearing seat, sealing cover is set, adopt the labyrinth type oil seal structure that oil pocket is sealed on it.
Compared with prior art the present invention has following advantage: when having avoided work, cooling fan and its power unit of driving be influencing each other of axial force between the two, improved both functional reliability and working life.For solving the problem that above-mentioned prior art exists, the invention provides a kind of bearing support that connects cooling fan and drive its power unit, can make the cooling fan stability of rotation smooth and easy, in the time of simultaneously can avoiding work, influencing each other of axial force between the two improved both functional reliability and working life.
Description of drawings

Embodiment
Be described in detail below in conjunction with 1 pair of the specific embodiment of the present invention of accompanying drawing: in bearing pedestal for cooling fan structure sectional view shown in Figure 1, bearing pedestal for cooling fan is made up of oil hydraulic motor 1, bearing seat 2, lubricating cup 3, sealing cover 4, transmission shaft 5, cooling fan fitting seat 6, rolling bearing 7, positioning ring 8, lock washer 9 etc., solderless access node structure relies on structure to connect fully.
The input end end face of bearing seat 2 directly is fixed on the oil hydraulic motor 1 that drives cooling fan, and the surface of contact sealing leaks outside to prevent the lubricant oil in the oil pocket.
The input end of transmission shaft 5 is that key is connected with the live axle of the oil hydraulic motor 1 that drives cooling fan, and the output terminal of transmission shaft 5 is connected with cooling fan by cooling fan fitting seat 6.The input end of transmission shaft 5 is provided with lock washer 9.
Be provided with oil leab in bearing seat 2, lubricant oil can add from lubricating cup 3, enters the lubricated rolling bearing 7 of oil pocket.
In order to prevent that lubricant oil output terminal direction to bearing seat 2 in the oil pocket from spilling, on the output terminal end face of bearing seat 2, sealing cover 4 is set, adopt the labyrinth type oil seal structure that oil pocket is sealed on it.
Though described embodiments of the present invention in conjunction with the accompanying drawings, those of ordinary skill in the art can make various distortion or modification within the scope of the appended claims.
