Abstract
The utility model relates to a fan motor, in particular to a vertical fan motor for engine, which resolves the defects of the vertical fan motor foe engine in the prior art that the shaft is easy being burned and weared during rotating with high speed. The utility model comprises a rotating shaft driving the fan and four points contacting ball bearings arranged between the non-transmission end of the rotating shaft and a frame as well as a single line cylinder roller bearing positioned between the non-transmission end of the rotating shaft and the frame. The capacity of the motor beared vertical force increases 90 per cent and the beared radial capacity of 50 per cent compared with the original structure; the bearing, with the service life under the biggest vibration acceleration, meets the mechanical property requirement of the vertical motor for engine. After implemented the bearing structure of single line cylinder roller bearing-four points contacting bearing, it has operated safely for 300 thousand Km at present without failures as bearing damage and rupture of maintain rack, which provides guarantee for normal operation for engine.
Description
Technical field
The utility model relates to a kind of fan electromotor, is specially the vertical fan electromotor of a kind of locomotive.
Background technology
The fan electromotor of traditional bearing structure (as figure one) comprises the rotating shaft 3 that drives fan, and between the non-transmision end of rotating shaft 3 and the support 1 is cylinder roller bearing 5, is double-row angular contact bal bearing 6 between the driving end of rotating shaft and the support 1.When main line moved, locomotive running speed was higher, when crossing track, produced dither; Because the locomotive vertical vibration is excessive, the maximum vibration acceleration reaches 60m/s
2, and the unbalanced moments of fan is bigger, during high speed rotating, the plain bearing that support is had fan produces bigger radial load, cause the life-span of bearing to be reduced, calculate by shaft strength analysis and bearing life, the discovery original structure is worked as the axial force acceleration and is reached 20m/s
2, bearing life is original 15%, and reaches 50m/s when the axial force acceleration
2, bearing life is 2%, can not satisfy former designing requirement, faults such as bearing burnt, retainer fracture frequently take place in motor after 200,000 kilometers of operations.
Summary of the invention
The utility model for solve the locomotive that exists in the prior art with the axle of vertical fan electromotor bearing when the high speed rotating burn out easily, wear problems and provide a kind of locomotive vertical fan electromotor with new structure.
The utility model is realized by following technical scheme, the vertical fan electromotor of a kind of locomotive, comprise the rotating shaft that drives fan, be provided with four-point contact ball between the non-transmision end of rotating shaft and the support, be provided with single row roller bearing between the driving end of rotating shaft and the support.Four-point contact ball has carried the axial force of the acceleration that the deadweight, locomotive up-down vibration of fan produce in the rotating shaft rotating process.
The type drive of motor end mainly is subjected to radial load, and the single row roller bearing radial force is better, and non-transmision end mainly is subjected to the impact of vibration acceleration generation and the deadweight of rotor, and the four-point contact ball axially loaded is good.The energy force rate original structure that this motor bears vertical force increases by 90%, bearing radial force ability 50%, and bearing life satisfies locomotive vertical machine mechanical performance requirement under the situation of maximum vibration acceleration.After the bearing arrangement of single row roller bearing-four-point contact ball is implemented, 300,000 kilometers of safe operations at present, faults such as bearing burnt, retainer fracture did not appear in operational excellence more at present, and normal operation provides guarantee to locomotive.
