Description

Export axle allocation mechanism
Technical field
The utility model belongs to technical field of transmission equipment, and in particular to a kind of output axle allocation mechanism.
Background technique
As shown in Fig. 4, existing output shaft and speed reducer fit system are as follows: output shaft one end protrudes into speed reducer and passes through key Connection transmission, the other end stretch out speed reducer and connect idler wheel;In the process of running, due to the high-speed rotation of output shaft, axis is easily caused To play;Only one axial positioning step on the mechanism output shaft can only prevent axial lower play, can not prevent output shaft Upward play;The power of the upward play of output shaft acts on bearing, and since bearing outer ring both ends are limited, bearing inner race is then defeated It is detached under the action of the upward play power of shaft, leads to bearing damage.
Utility model content
The purpose of the utility model is to provide a kind of output axle allocation mechanisms, by output shaft tail end setting locking knot Structure increases the axially position of output shaft other direction, reduces the play phenomenon up and down in output shaft operational process, and extending bearing makes Use the service life.
Purpose of the utility model is realized as follows: a kind of wheel body exports axle allocation mechanism, including speed reducer, output Mounting hole is arranged in axis, speed reducer, and output shaft cooperates in mounting hole, and speed reducer is stretched out in one end of output shaft;It is arranged on output shaft Positioning step, positioning step are contradicted in speed reducer front end face, and the mounting hole extends to speed reducer rear end face, speed reducer rear end face Conflict has lock washer, is connected with clamping screw between lock washer and the end face of the output shaft other end.
Further, spring washer is arranged on the clamping screw, spring washer is located at lock washer and clamping screw Between head.
Further, the end face of the output shaft other end is located in mounting hole, and keeps between the lock washer One fixed spacing.
Further, the clamping screw is vertically connected on the end face center of the output shaft other end.
Further, caulking groove is arranged in speed reducer front end face in the mounting hole, and the positioning step cooperation is in caulking groove It is interior.
Further, bearing is arranged on the output shaft, speed reducer front end face is fixed with gland, bearing outer ring both ends limit Between gland and speed reducer front end face, bearing inner race limits positioning step in caulking groove for position.
Compared with the prior art, the utility model has prominent and beneficial technical effects that:
The utility model is matched by extending output shaft, and in the axial positioning structure of output shaft tail portion setting other direction Close positioning step realize output shaft can not up and down play purpose, preferably protect bearing.
Detailed description of the invention
Fig. 1 is the scheme of installation that axle allocation mechanism is exported in the utility model embodiment;
Fig. 2 is the partial enlarged view of Fig. 1;
Fig. 3 is the structural schematic diagram of speed reducer;
Fig. 4 is the scheme of installation for exporting axle allocation mechanism in the prior art.
Appended drawing reference: 1, idler wheel is exported;2, output shaft;2a, positioning step;3, gland;4, bearing;5, speed reducer;5a, peace Fill hole;5b, caulking groove;6, clamping screw;7, spring washer;8, lock washer.
Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
A kind of output axle allocation mechanism, including speed reducer 5 specifically see that mounting hole 5a, mounting hole 5a is arranged in Fig. 3, speed reducer 5 Through the front/rear end of speed reducer 5, and caulking groove 5b is set at front end face;In conjunction with Fig. 1, output shaft 2 is combined in mounting hole 5a, 2 one end of output shaft is stretched out from 5 front end face of speed reducer, and is connected with the export structures such as output idler wheel 1;Positioning is set on output shaft 2 Step 2a, positioning step 2a cooperate in caulking groove 5b;Bearing 4 is arranged on output shaft 2, bearing 4 is located above positioning step 2a, 4 inner ring of bearing limits positioning step 2a in caulking groove 5b, gland 3 is combined with outside 4 outer ring of bearing, gland 3 passes through fastener It is fixed on 5 front end face of speed reducer, thus Limit Bearing 4.
2 other end of output shaft is extended downward into close to 5 rear end face of speed reducer combined with Figure 1 and Figure 2, in 5 rear end face of speed reducer The lock washer 8 that upper conflict has size to be greater than mounting hole 5a, the axial internal screw thread of the end face center setting of 2 other end of output shaft Hole, the screw rod of clamping screw 6 pass through lock washer 8, protrude into mounting hole 5a and be threadedly coupled with internal thread hole, apply to output shaft 2 Add downward axial lock clamp force;Downward play phenomenon of the positioning step 2a from 5 front end face of speed reducer limitation output shaft 2, lock pad Piece 8 is then from the upward play phenomenon of 5 rear end face of speed reducer limitation output shaft 2;To realize the axis in the process of running of output shaft 2 To stability, reduce influence of the play to bearing 4.
The other end of output shaft 2 is arranged in mounting hole 5a herein, and does not extend out mounting hole 5a, is to guarantee to lock Gasket 8 and output shaft have certain spacing between 2 end face, and when clamping screw 6 axially downwardly draws output shaft 2, output shaft 2 is being pacified Dress hole 5a has certain axially downwardly activity;In order to realize the locking of clamping screw 6, the sheathed spring pad on clamping screw 6 Circle 7, spring washer 7 is located between 6 head of lock washer 8 and clamping screw.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without deviating from the technical principle of the utility model, several improvement and replacement can also be made, these change It also should be regarded as the protection scope of the utility model into replacement.
