Abstract
The utility model discloses an induced draught fan motor bearing pedestal lubrication composition comprising a bearing pedestal, a bearing inner end cap and a bearing outer end cap; a ball bearing is arranged in an inner side of the bearing pedestal; a cylinder roller bearing is arranged on an outer side of the bearing pedestal; an inner lubricating oil cavity is arranged between the ball bearing and the bearing inner end cap; an outer lubricating oil cavity is arranged between the cylinder roller bearing and the bearing outer end cap; the bearing pedestal is provided with two oil injection holes, wherein one oil injection hole is connected with the outer lubricating oil cavity, and the other oil injection hole is connected with the inner lubricating oil cavity. The advantages are that the induced draught fan motor is observed after 24 hours of operation, and in a high temperature season of July, the bearing temperature is 42 DEG C in daytime and 38 DEG C in night time, so operation state is excellent, and operation requirements of the equipment are satisfied, thereby providing effective guarantee for long term stable safe operation of the equipment.
Description
Technical field
The utility model relates to a kind of id-motor bearing pedestal lubrication system.
Background technology
The induced draft fan unit that is applied to CFBB removes blower fan, and this is external, main also have fluid coupling, motor, slow rotating device, regulating device for differential guide vane, blower fan to import and export the compositions such as expansion joint, can motor normally move, be one of visual plant of the whole blower fan unit of impact, and whether the vibration of bearing, temperature index are normally the key links whether motor normally moves.
Id-motor drive end bearing moves under the high temperature environment in 90 ℃ of left and right for a long time, has had a strong impact on the long period stability and safety operation of equipment.It mainly causes because motor bearing seat structural design is unreasonable.Motor drive terminal bearing is two dish bearings, near inboard bearing, it is ball bearing, outside is cylinder roller bearing, two dish bearing combinations are installed, the lubricated employing lithium saponify of bearing is forced to inject lubricated, two grease fitting difference horizontal distribution are in both sides, lubricating oil all enters in the cavity of bearing pedestal innermost end, inboard bearing can be lubricated fully, outboard bearing Lubrication Design thinking is that lubricating grease is inside forced or splashed by bearing roller to enter, after dismounting, observe near outboard bearing and almost belong to oil-free lubrication state, outboard bearing is worked under the semi-dry friction state of being everlasting, it is the main cause that causes bearing temperature high.
Utility model content
The purpose of this utility model is to provide a kind of id-motor bearing pedestal lubrication system.
The purpose of this utility model is implemented by following technical scheme, a kind of id-motor bearing pedestal lubrication system, it comprises bearing pedestal, end cap inside bearing, end cap outside bearing, described bearing pedestal inner side is provided with ball bearing, described bearing pedestal outside is provided with cylinder roller bearing, inside described ball bearing and described bearing, between end cap, be provided with inner side lubricating oil cavity, outside described cylinder roller bearing and described bearing, between end cap, be provided with outside lubricating oil cavity, described bearing pedestal is provided with two oil filler points, a described oil filler point is communicated with described outside lubricating oil cavity, give the cylinder roller bearing oiling in outside, described in another, oil filler point is communicated with described inner side lubricating oil cavity, gives the ball bearing oiling of inner side.Such two dish bearings have all obtained lubricated fully, and bearing temperature has just lowered naturally.
The utility model has the advantage of, every dish bearing is provided with the oiling passage of specializing in, and can guarantee that two dish bearings are lubricated fully.Id-motor is observed through operation for 24 hours, and in the high temperature season in July, the bearing temperature on daytime is 42 ℃, be 38 ℃ night, and operation conditions is good, met the operation needs of equipment, for the long period stability and safety operation of equipment, provide strong assurance.Working strength and the useful life of bearing pedestal have been extended.
