Abstract
The utility model discloses a kind of locking nut anti-loose structures of cylindrical mixer Idler bearing, including roller carrier shaft, it is connected through a screw thread on carrying roller shaft end and the locking nut with left hand thread is set, uniformly four keyways are arranged in interval on the axial periphery face of carrying roller shaft end, uniformly 8 grooves are arranged in interval in the locking nut end face outside, radial arrangement of 8 grooves each along locking nut, it is respectively inlaid in four keyways by the fixed four anti-loose keies of bolt spacings, the lower end of four anti-loose keies in groove.The utility model, which can guarantee, generates nut in production enough locking torque, eliminates the accident that the carrying roller failure caused by bearing lock nut rotation loosens causes equipment downtime.
Description
Technical field
The utility model is related to a kind of locking nut anti-loose structures of cylindrical mixer Idler bearing.
Background technology
Sintering Plant batch mixer is mainly by transmission device, cylinder assembly, support device, catch wheel device, transmission, lube system
The compositions such as system, feeding equipment and material scattering preventing shield, discharge device, water injector, waste gas exhausting device.Cylinder is round steel construction.
Respectively there are one rolling rings at both ends, are sitting on four carrying rollers and are rotated.The feed end of cylinder mixing machine drum body is higher than discharge end, makes cylinder
Body has certain inclination angle.Up to 63 tons, four carrying rollers bear entirely to turn round weight in general 265m2 mixing machine of sintering machine production processes
Partial weight, and make cylinder, rolling ring smooth rotation.Support roller device uses ringfeder rolling bearing, design, the fixed roller carrier shaft of manufacture
The locking screw for holding inner ring is dextrorotation, and locking using conventional check washer.Sintering put into operation occurred so far it is a lot of
Generate heat machine halt trouble and 2 lubricating grease pyrophoricity accidents.Analysis finds, two carrying rollers of batch mixing machine actuating device side, close
The operating rotation direction of batch mixing machine drum body exit side roller carrier shaft is consistent with bearing lock nut rotation direction, and when rotating Vortex the more can turn the more loose；
Secondly, check washer cannot meet the torsional forces that actual production rotation generates, and lead to locking failure.Bearing block is caused to generate heat, such as
It was found that, processing not in time, can seriously lead to bearing damage, lubricating grease burning in carrying roller roll surface lubrication groove, cause fire disaster and
Equipment breakdown.
Invention content
The purpose of this utility model is to provide a kind of locking nut anti-loose structures of cylindrical mixer Idler bearing, can
Eliminate the hidden danger of the failure caused by bearing lock nut rotation loosens.
The purpose of this utility model is achieved in that a kind of anti-untwisting of locking nut of cylindrical mixer Idler bearing
Structure, including roller carrier shaft are connected through a screw thread on carrying roller shaft end and the locking nut with left hand thread are arranged, carrying roller shaft end
Axial periphery face on uniformly interval four keyways are set, uniformly interval is arranged 8 in the locking nut end face outside
A groove, 8 grooves each along locking nut radial arrangement, by the fixed four anti-loose keies of bolt spacings in groove, four
The lower end of a anti-loose key is respectively inlaid in four keyways.
The utility model processes the bolt hole of 8 grooves and fixed anti-loose key in locking nut side, while on roller carrier shaft
4 keyways of symmetrical machining require adjustment locking nut keyway and the corresponding position of carrying roller shaft key groove, installation 4 according to bearing clearance
The anti-loose key of part, is used in combination fixing bolt to fix, and it is locking to make original check washer into key；Locking nut is prevented by the bearing capacity of key
It loosens.Ensure to generate nut in production enough locking torque, eliminate because bearing lock nut rotation loosen cause carrying roller therefore
Barrier causes the accident of equipment downtime.
Description of the drawings
The utility model is described in further detail below in conjunction with attached drawing.
Fig. 1 is the main view cross-sectional view of the utility model；
Fig. 2 is the side structure schematic diagram of the utility model locking nut.
Specific implementation mode
A kind of locking nut anti-loose structure of cylindrical mixer Idler bearing, as shown in Figure 1 and Figure 2, including roller carrier shaft 6, support
It is connected through a screw thread on 6 end of roll shaft and the locking nut 1 with left hand thread is set, the axial periphery face of 6 end of roller carrier shaft
Four keyways 5 are arranged in upper uniformly distributed interval, are uniformly spaced in 1 end face outside of locking nut and 8 grooves 2,8 are arranged
Groove 2 is each along the radial arrangement of locking nut 1, and groove 2 is interior to be spaced fixed four anti-loose keies 4 by bolt 3, and four locking
The lower end of key 4 is respectively inlaid in four keyways 5.
Claims (1)
