Abstract
The utility model discloses a not fragile band pulley connection structure mainly relates to the band pulley and connects technical field, including axle, flange, band pulley and two dish bearings, two dish bearings all set up in the band pulley inside and concentric with the band pulley, and the axle passes flange and two dish bearings, and the connection can be dismantled to flange and axle, and the flange setting just can dismantle the connection with the band pulley in the terminal surface outside of band pulley. The belt wheel of the utility model is provided with the bearing which is not in direct contact with the shaft, thereby reducing the surface abrasion of the shaft; the shaft is set to be the spline shaft, the belt wheel is connected with the spline shaft through the flange and the spline, the connection strength is increased, the belt wheel is not easy to damage, the flange can be directly replaced even if the belt wheel is damaged, the labor cost is reduced, the time for replacing parts is saved, and the cost is saved.
Description
Technical Field
The utility model relates to a band pulley connection structure, especially a not fragile band pulley connection structure.
Background
Traditional band pulley and axle are all through the key-type connection, and such connection easily produces wearing and tearing through long-time operation, just need change after the keyway wearing and tearing of axle, and this kind of condition both time-wasting also increases the running cost.
SUMMERY OF THE UTILITY MODEL
The utility model provides a simple structure's not fragile band pulley connection structure has solved the easy wearing and tearing that exists among the prior art, the difficult problem of changing, cost are higher.
The utility model discloses a solve the technical scheme that above-mentioned technical problem adopted and be: including axle, flange, band pulley and two dish bearings, two dish bearings all set up in the band pulley inside and with the band pulley concentric, the axle passes flange and two dish bearings, the connection can be dismantled to flange and axle, the flange setting just can dismantle with the band pulley in the terminal surface outside of band pulley and be connected.
Preferably, the shaft is provided with a key, and the shaft is connected with the flange through the key.
Preferably, the shaft is a splined shaft and the keys are splines.
Preferably, the shaft is provided with a shaft sleeve, and the two disc bearings are sleeved on the shaft sleeve.
Preferably, a retainer ring is arranged between the two adjacent end faces of the two disc bearings, and the retainer ring is sleeved on the shaft sleeve.
Preferably, a bearing cap for fixing the bearing position is connected to the end face of the pulley on the side away from the flange by a plurality of screws.
Preferably, the pulley is connected by a plurality of screws and a flange.
Preferably, the screws are all countersunk head screws, and the number of the screws is 4-8.
The utility model adopts the above structure, following advantage has: the belt wheel is provided with the bearing, so that the belt wheel is not in direct contact with the shaft any more, and the surface abrasion of the shaft is reduced; the shaft is set to be the spline shaft, the belt wheel is connected with the spline shaft through the flange and the spline, the connection strength is increased, the belt wheel is not easy to damage, the flange can be directly replaced even if the belt wheel is damaged, the labor cost is reduced, the time for replacing parts is saved, and the cost is saved.
Drawings
Fig. 1 is a schematic view of the vertical full-section structure of the present invention.
In the figure, 1, a bearing; 2. a shaft; 3. a key; 4. a flange; 5. a pulley; 6. a retainer ring; 7. a bearing cap; 8. a shaft sleeve; 9. and (4) screws.
Detailed Description
In order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments in combination with the accompanying drawings.
As shown in fig. 1, two dish bearings 1 all set up at band pulley 5 inside and with band pulley 5 concentric, axle 2 passes flange 4 and two dish bearings 1, flange 4 and axle 2 can dismantle the connection, flange 4 sets up the terminal surface outside of band pulley 5 and can dismantle the connection with band pulley 5, be provided with key 3 on the axle 2, axle 2 passes through key 3 and flange 4 and connects, axle 2 is the integral key shaft, key 3 is the spline, be provided with axle sleeve 8 on the axle 2, two dish bearings 1 all suit are on axle sleeve 8, be provided with retaining ring 6 between the adjacent both ends face of two dish bearings 1, retaining ring 6 suit is on axle sleeve 8, band pulley 5 is connected with the bearing cap 7 that is used for fixed bearing 1 position through a plurality of screws 9 on the terminal surface of one side of keeping away from flange 4, band pulley 5 is connected with flange 4 through a plurality of screws 9, a plurality of screws 9 all are countersunk screw, the quantity is 4 ~ 8.
During operation, fix the suit on axle sleeve 8 with two dishes of bearings 1 through retaining ring 6 and bearing cap 7, avoid taking place the axial float, band pulley 5 passes through flange 4 and key and hub connection, and band pulley 5 drives flange 4 and rotates, and flange 4 passes through 3 drive shaft 2 rotations of key, and band pulley 5 does not with axle 2 direct contact, and axle 2 is difficult wearing and tearing or damage like this, if damage can directly change flange 4 or screw 9, and need not change axle 2.
Wherein, bearing 1, band pulley 5, countersunk screw, integral key shaft and spline are all prior art.
The above-mentioned specific embodiments can not be regarded as the restriction to the scope of protection of the utility model, to technical personnel in this technical field, it is right the utility model discloses any replacement improvement or transform that embodiment made all fall within the scope of protection of the utility model.
The parts of the present invention not described in detail are the known techniques of those skilled in the art.
