Abstract
The utility model discloses an aircraft instrument bearing, which solves the problems of the prior aircraft instrument bearing that the work precision of the aircraft instrument is influenced by the error which is accumulated during the processing and the reading error of the instrument is large, and the aircraft instrument bearing comprises a rotating shaft, a bearing main body which is mounted on the rotating shaft and a flange which is connected with the end part of the rotating shaft, and is characterized in that the flange is integrated with the rotating shaft into a whole body, and the flange and the rotating shaft are integrally formed, so that the periphery of the connection position between the flange and the rotating shaft is provided with a chamfer angle surface.
Description
Technical field
The utility model relates to a kind of bearing, relates in particular to a kind of bearing that is used for aircraft instrument.
Background technique
On aircraft instrument, generally all need to be provided with bearing,, between each transmission shaft, realize smooth and easy transmission in order to power as the supporting member of relevant transmission shaft.Aircraft instrument is as a kind of precision type instrument, its reading whether accurate be with each transmission shaft between the accuracy of transmission of power be associated.For the usage requirement that guarantees that aircraft instrument is realistic, the required precision of these transmission paries in production and assembly process is very high.Existing aircraft instrument bearing all is that bearing body is assemblied in the rotating shaft, and an end of rotating shaft is connected with flange, and this flange is used for linking with other parts.Wherein, flange is to be connected to the end of rotating shaft by the mode of welding or be threaded, but after adopting this Placement, the coaxality of flange and rotating shaft can not be guaranteed.Successively flange and rotating shaft are being processed, and in the welding or the operating process that is threaded to both, can produce certain error respectively, in the present finished product rotating shaft of these error accumulations and final body, make that the up-to-standard rate of rotating shaft is lower, rub-moment and starting torque during its work are bigger, and the stability of rotating shaft transmission of power and accuracy can not be guaranteed, this is difficult to satisfy its job requirement concerning sensitivity requires high aircraft instrument, the accuracy of aircraft instrument reading can not guarantee.In addition, the aircraft instrument bearing of existing this structure after being assembled on the aircraft instrument, also needs to match with other more parts.As a kind of aircraft instrument of precision type instrument, its inner installing space own is little, and this has caused the assembly manipulation inconvenience of aircraft instrument on the one hand; Restriction owing to assembly space can not be given full play to the function of instrument on the other hand.
Summary of the invention
For overcoming the above-mentioned defective that existing aircraft instrument bearing is had, the technical problem that the utility model need solve is: a kind of novel aircraft instrument bearing is provided, machining accuracy of rotating shaft can be guaranteed on it, helps the accuracy of reading that instrument reflects.
Another technical problem that the utility model need solve is: a kind of aircraft instrument bearing of being convenient to assemble and can effectively control assembly error is provided.
For solving the problems of the technologies described above, the empty Yi Biao of a kind of Hang of the technical solution of the utility model Schedule-of-Routes bearing, comprise rotating shaft, be assemblied in bearing body in the rotating shaft, be connected the flange of roller end, it is characterized in that, described flange and rotating shaft are a single piece, they are one-body molded, and be connected with the rotating shaft periphery of position of flange has chamfer surface.Are flange and rotating shaft processed into blank for one turning, then its blank are carried out the fine finishing moulding, at last running in bearings body in rotating shaft? Application.Described chamfer surface is generally the cambered surface of ring-type, and this cambered surface is along the whole extending circumferentially of flange and rotating shaft touching position.
As preferably, be provided with connecting hole on the exterior edge face of described flange prejudicially, connecting hole is along the axial setting of rotating shaft.This connecting hole is used for cooperating with other biography parts grafting of aircraft instrument, to realize the transmission of power.
As preferably, described connecting hole is a blind hole.
For effectively reducing number of components and parts on this aircraft instrument bearing, improve assembling speed, inner ring and rotating shaft in the described bearing body are connected as a single entity, and the raceway groove on this inner ring is formed on the outer circumferential face of described rotating shaft.After bearing body is assemblied in the rotating shaft, in rotating shaft, do not need to be provided with other the bounding means that is used for bearing body is carried out axially locating, think that the inside of aircraft instrument vacates certain space, be convenient to assemble in these spaces other some functional parts, so that the giving full play to of aircraft instrument function.
As preferably, be socketed with joint sleeve on the outer ring of described bearing body, transition fit between the outer ring of joint sleeve and bearing body.Joint sleeve is used to protect bearing body, and after this bearing was assembled on the aircraft instrument, joint sleeve directly contacted with miscellaneous part.
As preferably, described joint sleeve is a blind nested structure, and described rotating shaft is plugged in the joint sleeve away from an end of flange, is provided with connecting column prejudicially on the cecum face of joint sleeve, and connecting column extends axially along joint sleeve.This connecting column makes joint sleeve be convenient to realize stable position in aircraft instrument, makes bearing body have good stable.
As preferably, described connecting column and joint sleeve are a single piece, and they are one-body molded.They are formed in one, and have made things convenient for manufacturing, and gained product qualified rate height.
Therefore, the beneficial effects of the utility model:
Because in this aircraft instrument bearing, flange and rotating shaft are one whole, they are integrated, with respect to flange and rotating shaft is that manufacturing respectively and the mode by welding link together, reduced the cumulative error of product, accuracy and sensitivity that this is beneficial to the aircraft instrument bearing action make the accuracy of reading height that aircraft instrument reflected.Inner ring and rotating shaft in the bearing body are connected as a single entity, and have reduced number of components and parts, have improved the convenience of the empty instrument assembling of space flight.
