Abstract
The utility model relates to a drum-shaped tooth coupling, which is suitable for the transmission on rotary disk aerators or other heavy machines. The utility model comprises an internal tooth semi-coupling which is connected with a speed reducer driving shaft and an external tooth semi-coupling which is connected with a rotation shaft, and the drum-shaped external tooth of the external tooth semi-coupling and the internal tooth of the internal tooth semi-coupling are engaged. The driving shaft is provided with a self-aligning bearing which is arranged in the inner hole of the external tooth seimi-coupling of the self-aligning bearing and is contacted and matched with the external tooth semi-couling. The utility model can bear radial load of a plurality of tons, and meanwhile, the utility model can accomplish automatic aligning. The good running of a transmission system can protect the operation safety and quality of a main machine and a transmission shaft, and the utility model can save power consumption, decrease maintenance load and extend service life.
Description
Technical field
The utility model relates to the coupling that a kind of mechanical transmission is used, and refers to a kind of crown gear coupling especially, is specially adapted to the transmission on plate-spinning aerator or other heavy machinery.
Background technique
Crown gear coupling generally is made up of inside and outside gear ring and end cap etc., external tooth directly meshes transmitting torque in relying on, when using it for the plate-spinning aerator, because the axle of aerator is that weight is very big, need establish a support in addition, three strong points are just arranged like this, for an axis if there is any to go wrong, some pressure at place will be excessive at certain, thereby influence is rotated.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency, but provide a kind of can transmission the crown gear coupling of bearing load again, and can be under the situation of decentraction self-aligning, improvements of the present utility model are selfaligning bearing is installed on driving shaft, place the endoporus of external tooth half-coupling and contact with the external tooth half-coupling simultaneously to connect.Specifically be achieved like this: crown gear coupling, comprise the internal tooth half-coupling that connects with the speed reducer driving shaft, the external tooth half-coupling that connects with rotating shaft, the cydariform external tooth of external tooth half-coupling and the engagement of the internal tooth of internal tooth half-coupling, it is characterized in that being equipped with on the driving shaft selfaligning bearing, described selfaligning bearing places the endoporus of external tooth half-coupling and contacts with the external tooth half-coupling and connects.By contacting the selfaligning bearing that connects with external tooth half shaft coupling, it can be the double-row self-aligning ball bearing, it also can be painstaking bigger biserial spheric roller bearing, like this in transmitting torque, can be directly delivered to reducer pedestal to the whole weight of oxidation ditch plate-spinning aeration arbor system, avoid being provided with again in addition bearing spider, more reasonable stressed by two point-supported axis, this in addition application that can transmit the crown gear coupling of suspended load by cydariform external tooth and selfaligning bearing, strengthened center adjusting value, make coupling reach 1 ° 30 ' center adjusting value and the axial stretching amount of δ≤5mm, thereby make the transmission system can good operation.
The utility model is provided with seal ring in addition to guarantee the lubricated of parts between external tooth half-coupling and internal tooth half-coupling.
The diameter of axle that coupling of the present utility model transmitted can design according to actual needs, and the best application diameter of axle is between the φ 80mm-φ 600mm.
The utility model is just by installing selfaligning bearing on driving shaft; selfaligning bearing places the endoporus of external tooth half-coupling and contacts with the external tooth half-coupling simultaneously and connects; make coupling can bear several tons of radial loads and transmitting large torque; realize self-aligning simultaneously; the good operation of transmission system can be protected the security of operation and the quality of main frame and transmission shaft well; energy efficient reduces maintenance load, has prolonged working life.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
