Abstract
A drum-shaped tooth safe coupler is divided into three parts; a driven end flange is connected with an internal tooth sleeve by bolts; a drive end flange is connected into a whole with a coupler and an external tooth sleeve and is then connected with a safety pin; the internal tooth is designed as a direct tooth; the external tooth is designed as a drum-shaped tooth; two core adjusting roller bearings are adopted between the coupler and the external tooth sleeve to support the transmission; a spigot is adopted for positioning; the interference fit is adopted between an bearing external ring and an external tooth sleeve internal hole; the dynamic matching is adopted between the bearing internal ring and the coupler. The connection positioning among the three parts are exact; when in normal work, the coupler wholly transmits larger torque to condensate the radial position, angle displacement and axial displacement between two shafts. When malfunction or disoperation happens in line rolling, the drive end disconnects transmission from the driven end and rotates by inertia; the driven end stops rotation, thus having the safe protection function on a speed increasing box, a motor and a coupler body. The utility model has the advantages of light weight, good rigidity, simple manufacture process, good reliability, saved manufacture cost, etc.
Description
Technical field:
The utility model belongs to the coupling technical field, a kind of crowned teeth safety coupling.
Background technique:
Conventional crown gear coupling just is used for connecting diaxon, it is together rotated and a kind of rigidity high movable coupling of transmitting torque, and this coupling is the connection of gear as axle, transmitting torque, the angular displacement of compensation diaxon.But do not have the safety protection effect with coupling self to coupled.In high-speed rod-rolling mill finishing mill unit, the coupling of going between the axle at speedup box shaft and finishing mill gear distribution box requires not only have transmission than high pulling torque, to possess also when compensating the radial position, angular displacement of two between centers and axial displacement that the rolling line of preventing breaks down and during misoperation, moment increases the function of causing damage for speedup box, motor and coupling itself suddenly.
Summary of the invention:
In order to overcome the above-mentioned defective of prior art; the utility model provides a kind of crowned teeth safety coupling; this crowned teeth safety coupling is to go into axle for connection speedup box shaft and finishing mill gear distribution box in high-speed rod-rolling mill finishing mill unit; the realization moment of torsion transmits, and protection speedup box, motor and coupling self.
In order to realize the foregoing invention purpose, the utility model has adopted following technological scheme.
A kind of crowned teeth safety coupling, this coupling divide three parts, driven end flange and internal tooth casing Bolt Connection; The drive end flange is connected by safety pin with joining shaft, joining shaft and after external tooth cover is connected into one by lining with the three; Internal tooth is designed to straight-tooth, and external tooth is designed to crowned teeth, with two aligning roller bearing supporting transmissions, is located by seam between joining shaft and the external tooth cover; Bearing outer ring and external tooth cover endoporus are interference fit, and bearing inner race and joining shaft are for movingly.
Owing to adopted technological scheme as mentioned above, the utlity model has following good effect:
1, the drum type tooth is used for the transmission of coupling tooth, but transfer larger torque, and compensate radial position, angular displacement and the axial displacement of two between centers.
2, located by seam respectively between the crowned teeth safety coupling each several part, centering is easy during installation, and the operator changes safety pin, the time and labour saving.
3, the crowned teeth safety coupling adopts the supporting of aligning roller bearing, and bearing outer ring and external tooth cover endoporus adopt interference fit, and inner ring and coupling shaft adopt movingly, between external tooth cover and the coupling shaft safety pin are set.During proper functioning; coupling connects moving two ends of principal and subordinate and high speed rotating with it; whole transmitting torque; when generation of rolling line fault or misoperation, safety pin is cut off, and the transmission of principal and subordinate moved end disconnects; but drive end inertia rotates; and driven end stops operating, but the each several part axis is still on same straight line, thereby plays the effect of protection speedup box, motor and coupling self.
4, the crowned teeth safety coupling have that in light weight, good rigidity, manufacturing process are simple, good reliability, saving manufacture cost and other advantages.
Description of drawings:
Accompanying drawing is the structural drawing of crowned teeth safety coupling.
Among the figure: 1, driven end flange, 2, bolt, 3, internal tooth casing, 4, bearing, 5, external tooth cover, 6, safety pin, 7, lining, 8, joining shaft, 9, the drive end flange, 10, seam.
Concrete implementing measure:
The crowned teeth safety coupling divides three parts, and driven end flange (1) is connected with bolt (2) with internal tooth casing (3); Drive end flange (9) with connect with safety pin (6) with external tooth cover (5) again after joining shaft (8) links into an integrated entity with bolt, because in gear pair, the geometric parameter of profile of tooth and sideshake size have determined the maximum angular displacement that is allowed, this maximum angular displacement is the key factor that influences bearing capacity, therefore internal tooth adopts straight-tooth, and external tooth adopts crowned teeth; Adopt two aligning roller bearings (4) supporting between joining shaft and the external tooth cover, bearing outer ring and external tooth cover endoporus adopt interference fit, and bearing inner race and joining shaft adopt movingly, and each several part is located by seam (10) respectively.
Driven end and finishing mill gear distribution box are gone into axle and are connected during work, and drive end connects with the speedup box shaft.When accident generation or misoperation; safety pin is cut off; the transmission of principal and subordinate moved end disconnects; but drive end inertia rotates; and driven end stops operating; because the supporting role of bearing is arranged, driven end still can keep concentric with drive end, makes coupling play protection speedup box, motor and the effect of self when running up.
In order to install and remove coupling easily under not moving by the situation of online tool, it is floating type that the tooth drive part is designed to internal tooth, adopts external diameter centering, otherwise can be because some vibrations in transmission, the radially runout of internal tooth casing is strengthened, produce uneven running, influence the quality of transmitting torque.Internal tooth and outer teeth material all adopt the quenching with Subsequent tempering of alloy structure steel forgings, and the processing of gear shaping method is adopted in internal tooth tooth face hardness HB＞262; Generating process processing is adopted in external tooth tooth face hardness HB＞293, and interior external tooth grade of accuracy is 7 grades.Master and slave moved end connecting flange and joining shaft material adopt the quenching with Subsequent tempering of alloy structure steel forgings, and lagging material adopts alloy structure steel forgings carburizing and quenching to handle.Because the working speed of this coupling reaches 3000r/min, the intact back of each several part fine finishing single-piece is done the dynamic balancing check, needs integral body to do the dynamic balancing check after the whole assembling, and balance accuracy grade G6.3 guarantees that coupling turns round steadily when high speed.
Claims (1)
