Abstract
The utility model belongs to the drive device technical field and particularly relates to a belt conveyor tail wheel shaft sealing device. The belt conveyor tail wheel shaft sealing device comprises a tail wheel shaft and a bearing pedestal. A rolling bearing is arranged at the tail end of the tail wheel shaft. The bearing pedestal is arranged on a shaft neck position. Sliding friction between the tail wheel shaft and the bearing pedestal in operation is changed into rolling friction, and then friction losses are reduced. A bearing cover is arranged on the external end surface of the bearing pedestal, a felt seal ring is arranged on a shaft shoulder position, so that the bearing cover is only needed to regularly demount and filled with lubricating oil, then lubricating and sealing environment of the whole bearing is improved, and service life of the whole device is prolonged.
Description
Technical field
The utility model belongs to the driving device technical field, especially relates to a kind of belt conveyer tail-gear spindle sealing arrangement.
Background technology
Tail-gear spindle is supported on the slide through whole plain bearing in the existing belt conveyer spiral tensioning device, and slide can slide the plain bearing cascade oiling relatively on support.Screw rod runs through the nut on slide top, and when screw rod rotated, it is mobile together that slide drives tail-gear spindle, makes the load-transfer device tension.The lubricant effect of this belt conveyer spiral tensioning device is poor, and bearing weares and teares and externally easily deposition of screw thread easily, and damaged screw is adjusted difficulty.Therefore it is low to install workability, frequent et out of order, cost of maintenance man-hour.
The utility model content
The utility model can provide a kind of lubricated, the better belt conveyer tail-gear spindle of sealing effectiveness sealing arrangement.
In order to solve the problems of the technologies described above, provide following technical scheme: belt conveyer tail-gear spindle sealing arrangement comprises tail-gear spindle, bearing seat, the tail-gear spindle end is provided with antifriction-bearing box, the axle journal place is provided with bearing seat, and the bearing seat outer face is provided with bearing cap shim, and shaft shoulder place is provided with the felt seal ring.
Adopt above-mentioned technical scheme, in the utility model, the tail-gear spindle end of belt conveyer tail-gear spindle sealing arrangement is provided with antifriction-bearing box, and the axle journal place is provided with bearing seat, so the tail-gear spindle of running and the cliding friction between the bearing seat are become friction of rolling, thereby reduce friction loss.The bearing seat outer face is provided with bearing cap shim, and shaft shoulder place is provided with the felt seal ring, so only needs the regular bearing cap shim of taking apart, adds lubricating oil, has improved lubricated, the sealed environment of whole bearing, the service life of having improved whole device.
Further, described tail-gear spindle outside face is provided with axle sleeve, can protect tail-gear spindle.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model belt conveyer tail-gear spindle sealing arrangement.
The specific embodiment
As shown in Figure 1: belt conveyer tail-gear spindle sealing arrangement, comprise tail-gear spindle 1, bearing seat 2, tail-gear spindle 1 end is provided with antifriction-bearing box, the axle journal place is provided with bearing seat 2, bearing seat 2 outer faces are provided with bearing cap shim 3, and shaft shoulder place is provided with felt seal ring 4, and tail-gear spindle 1 outside face is provided with axle sleeve 5.
In the present embodiment, tail-gear spindle 1 end of belt conveyer tail-gear spindle sealing arrangement is provided with antifriction-bearing box, and the axle journal place is provided with bearing seat 2.Change plain bearing of the prior art into antifriction-bearing box, so in the running, the cliding friction between tail-gear spindle 1 and the bearing seat 2 becomes friction of rolling, thereby reduces friction loss.Bearing seat 2 outer ends are provided with bearing cap shim 3; shaft shoulder place is provided with felt seal ring 4; so only need the regular bearing cap shim 3 of taking apart; add lubricating oil; lubricated, the sealed environment of whole bearing have been improved; improved the service life of whole device, tail-gear spindle 1 outside face is provided with axle sleeve 5 simultaneously, can protect whole bearing not easy to wear.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; should be considered as protection domain of the present utility model, these can not influence effect and practical applicability that the utility model is implemented yet.
