The utility model has compact, simple and practical structure, and also has the advantages of convenient installation and easy maintenance in particular to the use of a plurality of large-scale shafting components.
Description
Technical field
The utility model belongs to engineering machinery shaft drive technical field, particularly relates to a kind of shaft drive.
Background technique
Axle is a strength member forming machinery, and it is supporting other rotating component revolutions and is transmitting moment of torsion, and it is connected with frame by bearing again simultaneously.All parts on shaft all center on shaft axis and do rotation motion, and having formed one is the assemblying body of benchmark---shaft components with the axle.So, when the discussion shaft components, can not only consider axle itself, also must maintain close ties with the total of axle system zero, parts.
At present, the structure of large-scale shaft components on big machineries such as some engineering machinery, mining machinery installed and used, and still continues to use traditional methods.Axle is directly connected in the outside frame of work by bearing.Yielding distortion when live axle bears big load.The shortcoming of this type of transmission device is a complex structure, and inconvenience is installed, and particularly repairs very difficult.And when easily damaged parts in the big profile shaft system such as seal ring etc. damaged, repairing not only needed to remove axle, bearing, but also needed to remove large-sized structural parts such as whole equipment, keeped in repair very inconvenient.
Summary of the invention
The utility model provides a kind of simple and practical shaft drive for solving the problem that existing known technology exists.
The shaft drive that the utility model provides, when axle drive parts on shaft was done rotation motion, the equipment of complete machine also will rotate around its shaft axis.When this transmission device is handled above-mentioned situation, increased bearing housing, can make axle avoid bearing huge additional load and deform.Specifically on bearing housing, be connected with a gland, it not only can reach the purpose that bearing compresses, and, also making only needs the gland that this step bearing put is pulled down when easily damaged partss such as replacing seal ring, baffle plate, just the easily damaged partss such as seal ring of axle together with bearing and required replacing can be taken out, and needn't remove whole equipment structure.
The utility model is taked following technological scheme:
Shaft drive is made up of live axle, driving sprocket wheel, bearing, bearing housing, gland, seal ring and end cap, its assembling linkage structure is: the two ends of axle are equipped with bearing, bearing is equipped with bearing housing outward, bearing housing is connected with frame with bolt, gland is housed on the bearing housing, and it is connected with bolt with bearing housing, is equipped with seal ring between axle and the bearing housing, seal ring is contained in the end cap, and axle is connected with sprocket wheel by key.
The utility model can also adopt following technical measures:
Above-mentioned shaft drive is characterized in being equipped with gland on the bearing housing, and gland is fastened on the bearing housing by bolt.
Above-mentioned shaft drive is characterized in that sprocket wheel is a split type, and sprocket wheel connects by two keys and bolt.Install and use bolt the two halves sprocket wheel fixedly is assemblied in live axle, live axle and sprocket wheel have keyway, and live axle and sprocket wheel are by the key transfer torque load.
Above-mentioned shaft drive is characterized in that end cap is a split type, and two and half end caps connect by bolt, and are connected on the bearing housing by bolt.
Above-mentioned shaft drive is characterized in that bearing is a tapered roller bearing, needs pretension and can bear big load.
Description of drawings
Fig. 1 linkage structure generalized section of the present utility model.
The utility model transmission device is embedded with by two bearings and reaches equipment and frame The purpose that connects. The ring flange that bearing overlaps an end is connected with frame by bolt. Namely in frame On increase thick circle cover of weldering, put at circle and be provided with the bolt hole, this bolt hole and bearing are overlapped one The bolt hole of end flanges dish aligns, and connects bolted with end face. Bearing at one end puts Be connected with a gland, and be bolted. Bearing is contained in the inner ring of bearing cover, simultaneously Also reach pre-tight purpose by this side pressure lid. Driving shaft supports by bearings at both ends. Drive Axle drives by two keys and drives chain crop rotation revolution motion. Sealing ring of the present utility model is contained in In the end cap, and be bolted and be fixed on bearing and put. But end cap is the dissection type end cap, Link together with bolt. Drive chain and become the dissection type sprocket wheel, and make two and half by bolt Wheel links together.
The advantage that the utlity model has and good effect:
1. put at bearing and be fixedly connected with a gland, pull down this gland, just axle can be connected Same bearing, sealing ring etc. easily decrease part and from then on hold taking-up, like this, and to axle, bearing And sealing ring just can carry out very easily dismounting or replacing.
2. sprocket wheel is the dissection type sprocket wheel, and it is next more convenient than the Integral chain wheel dismounting. And Be connected with axle by two keys, make the driving performance more reliable.
3. end cap is the dissection type end cap, and it gets up more convenient than the integral end cap dismounting.
4. equipment is connected with frame by the bearing cover, and like this, equipment just can be not Just can reach the order of doing the revolution motion around its axial line by directly being connected with axle . And equipment is then born by frame to the substantial load that complete machine brings, Thereby avoided driving bearing but huge load and guarantee higher safety system Number.
In sum, the utlity model has the structure compactness, simple and practical; Particularly right In the use of some large shaft parts, have again easy for installation, easy to maintenance etc. excellent The point.
