Description
One, technical field
The utility model belongs to geared machine, is specifically related to the driving mechanism of the medium-and-large-sized grinding machine of cement industry.
Two, background technique
Domestic large-scale cement grinding machine adopts the center transmission speed reducer to realize driving usually.The system layout space of this center transmission speed reducer is big, and the output shaft of capital investment height, particularly main gear reducer is directly to drive grinding machine by transmission shaft, and rotating speed is low, moment of torsion is big, the requirement reduction speed ratio is big, transmission capacity is big, thereby manufacture difficulty is big, the equipment manufacturing cost height; In addition, adopt the center transmission speed reducer also to be unfavorable for grinding the tail exhaust.In recent years, in order to overcome the drawback of center transmission speed reducer, begin to use the external nineties and ask that a kind of monolateral pair of transmission speed reducer in city drives the large-scale cement grinding machine.But, existing monolateral pair of transmission speed reducer, structurally have some serious problems: particularly its input shaft adopts 4 static indeterminacy supportings, make supporting point stressed uncertain, gear shaft stressed back distortion produces to be interfered, thereby driveline vibrations and increasing rapidly occur, finally cause broken teeth, off-axis, even gearwheel skids; Simultaneously, the housing structure of speed reducer only adopts somatotype up and down, and it is not quick detachable to cause importing gear shaft, and maintain and replace is inconvenience very; In addition, monolateral pair of transmission speed reducer of existing structure, driving gear to all carrying property of engagement synchronism, power dividing and all carrying property of grinding machine bull gear teeth directional load aspect all not really desirable.The existence of above-mentioned defective will certainly cause cement production line to be difficult to run well.
Three, summary of the invention
Goal of the invention of the present utility model is the problem at existing monolateral pair of transmission speed reducer existence, do structural improvement, make speed reducer compact structure, transmission efficiency height, safe and reliable to operation, easy to maintenance, and cost is lower, can guarantee the normal operation of large-scale cement grinding machine.
The technological scheme that the utility model adopted is as follows.
A kind of monolateral pair of transmission speed reducer, include an input shaft, floating axle and two parallel live axles up and down, the input gear is arranged on the input shaft, be equipped with one-level gearwheel and secondary small gear on the floating axle, be respectively fitted with dextrorotation secondary gearwheel or left-handed secondary gearwheel and self correction type small gear on two parallel up and down live axles, also include the speed reducer casing, it is characterized in that: input shaft adopts 2 radial bearings to realize 2 statically determinate structure supportings; The speed reducer casing is combined by left box body, upper box, right case and lower box four parts, to make things convenient for the dismounting maintenance of body.Its feature is that also the secondary small gear on the floating axle adopts a pair of herringbone tooth that is symmetrical in the one-level gearwheel, and the cylindrical bearing supporting that no axial limiting is adopted at the floating axle two ends realizes dynamically all carrying of power bi-shunting.On two parallel up and down live axles, offer the high pressure oil inlet hole respectively, and be provided with the reaming oil groove in the position of assembling dextrorotation secondary gearwheel or left-handed secondary gearwheel, so that the secondary gearwheel can circumferentially be rotated, the sideshake adjustment of self correction type small gear and grinding machine bull gear is even, realize that the engagement of self correction type small gear and grinding machine bull gear is synchronous fully.The self correction type small gear adopts the drum-type gear coupling assembling on the live axle, realizes that the axle of moment upward transmits; Adopt drum-type gear coupling and angular contact articulated bearing radial support, make the self correction type small gear can produce and follow the motion and adjusting automatically of grinding machine bull gear; The engagement driving of guaranteeing self correction type small gear and grinding machine bull gear is all carried along the tooth length direction.
The transmission process of monolateral pair of transmission speed reducer of the utility model is: energy is by the one-level gearwheel on the input gear driven floating axle on the input shaft, a pair of secondary small gear by being symmetrical in the one-level gearwheel is with power bi-shunting again, pass to the left and right secondary gearwheel that revolves on the two root architectures live axle identical, parallel symmetry up and down respectively, by self correction type small gear on the live axle and the engagement of grinding machine bull gear, turn round at last thereby drive cement mill.
Monolateral pair of transmission speed reducer of the utility model structure, owing to adopted 2 statically determinate structure supportings of input shaft radial bearing, supporting point is stressed to be determined, thereby the distortion behind stand under load of the defeated axle of input tooth is determined, can not produce interference, the accident that broken teeth, off-axis and the gearwheel of therefore having avoided prior art to occur skids takes place; The speed reducer casing adopts somatotype structure up and down, and keeping in repair for the dismounting of body provides great convenience; Simultaneously its power bi-shunting dynamically all carrying property is good, the self correction type small gear is good with synchronism all carrying property good, teeth directional load that the grinding machine bull gear meshes.In a word, monolateral pair of transmission speed reducer of the utility model structure, compact structure, transmission efficiency height, safe and reliable to operation, easy to maintenance, and cost is lower are well suited for the large-scale cement grinding machine supportingly, also are fit to the supporting use of large-scale lapping machine with other field.
