Description
Technical field
The utility model belongs to and connects securing means technical field, is specifically related to a kind of stacker-reclaimer bucket wheel live axle and connects fastening device with speed reducer.
Background technique
Bucket wheel reducer adopts Floating connection mode to connect with bucket wheel axle and combines, and is born the weight of speed reducer 3.4t by bucket wheel axle as fulcrum.For meeting duty requirements, bucket wheel axle and speed reducer output shaft spline tooth are connected end and are designed to be that a short cylindrical platform coordinates with cylindrical hole by former design, meet the coaxality requirement of speed reducer output shaft and bucket wheel axle.This design seems reasonable, but in practical application, for the ease of installing, end coordinates the fit tolerance (± 0.025) that employing is larger, the coaxial accuracy of bucket wheel reducer output shaft and bucket wheel axle is caused to reduce, there is slanted angle in diaxon axis, progressively can cause the wearing and tearing of shaft end, axis hole in equipment operation process.Along with the increasing of wearing and tearing, bucket wheel axle axis and speed reducer output shaft shaft angle increase, and the tilt angle of increase can produce an axial thrust load in rotary motion, and under axial thrust load effect, bucket wheel reducer disengaging bucket wheel axle causes and comes off.
Existing design comes off under axial thrust load effect to prevent bucket wheel reducer, bucket wheel axle devises locking ring device, fixes bucket wheel reducer with locking ring device.But this locking ring device design existing defects: the one end connected with bucket wheel axle can meet operating mode, the one end connected with speed reducer output shaft, only links together by 6 M16 bolts and speed reducer output shaft spline tooth sleeve end.The bucket wheel reducer occurred in recent years is separated release failure with bucket wheel axle, and main cause is exactly these 6 M16 connecting bolts or fracture or " stripped thread ", cause keep in repair after breaking down more difficult.This illustrates this design existing defects, can not meet working condition requirement.
Summary of the invention
The purpose of this utility model is exactly will provide a kind of in operation process, to be frequently separated the fault come off with bucket wheel axle for solving stacker-reclaimer bucket wheel reducer, can equipment reliability be improved, and be convenient to the dismounting of bucket wheel axle and bucket wheel reducer connect positioning device.
The utility model is achieved through the following technical solutions:
A kind of stacker-reclaimer bucket wheel live axle connects fastening device with speed reducer, comprise bucket wheel axle 1, be arranged on the tapered roller bearing 2 on bucket wheel axle 1 one end, tapered roller bearing 2 is socketed with speed reducer axle sleeve 3, speed reducer axle sleeve 3 is connected with speed reducer output shaft 4, speed reducer axle sleeve 3 is coaxially connected by the first snap ring 5 with bucket wheel axle 1, bucket wheel axle 1 the other end is provided with fastening, this fastening is by the first end plate 6, second snap ring 7, 3rd snap ring 8 and the second end plate 9 form, the first described end plate 6, second snap ring 7, 3rd snap ring 8 and the second end plate 9 are socketed on bucket wheel axle 1 successively.
In order to better realize the purpose of this utility model, the first snap ring 5 is taper snap ring.
Compared with prior art, the beneficial effects of the utility model are:
1) tapered roller bearing 2 of bucket wheel axle 1 one end installation, the outer ring of circular cone rod bearing 2 is arranged in speed reducer axle sleeve 3 spline tooth axle sleeve hole, facilitate bucket wheel axle 1 to locate with " centering " of speed reducer output shaft 4 spline tooth axle sleeve hole, and convenient control bucket wheel axle axis and speed reducer output shaft shaft angle.
2) common snap ring is modified as the first snap ring 5 of tapered structure, bucket wheel axle 1 and the join strength of speed reducer axle sleeve 3 can be improved on the one hand, be convenient to bucket wheel axle 1 on the other hand and overhaul with speed reducer dismounting.
3) the utility model is thoroughly eliminated stacker-reclaimer bucket wheel reducer and is separated release failure with bucket wheel axle, improves production operation efficiency, and the input of the time that minimizing overhaul of the equipments takies, manpower, fund, removes hidden trouble of equipment, improves equipment reliability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. bucket wheel axle, 2. tapered roller bearing, 3. speed reducer axle sleeve, 4. speed reducer output shaft, 5. the first snap ring, 6. the first end plate, 7. the second snap ring, 8. the 3rd snap ring, 9. the second end plate.
Embodiment
Below the utility model is described further:
As shown in Figure 1, a kind of stacker-reclaimer bucket wheel live axle connects fastening device with speed reducer, comprise bucket wheel axle 1, be arranged on the tapered roller bearing 2 on bucket wheel axle 1 one end, tapered roller bearing 2 is socketed with speed reducer axle sleeve 3, speed reducer axle sleeve 3 is connected with speed reducer output shaft 4, speed reducer axle sleeve 3 is coaxially connected with first snap ring 5 of bucket wheel axle 1 by cone structure, bucket wheel axle 1 the other end is provided with fastening, this fastening is by the first end plate 6, second snap ring 7, 3rd snap ring 8 and the second end plate 9 form, wherein the first end plate 6, second snap ring 7, 3rd snap ring 8 and the second end plate 9 are socketed on bucket wheel axle 1 successively.
The utility model is when specifically using, tapered roller bearing 2 outer ring is arranged in the speed reducer axle sleeve 3 of speed reducer output shaft 4 spline tooth, first snap ring 5 is enclosed within bucket wheel axle 1, bucket wheel reducer and bucket wheel axle 1 are assembled, tapered roller bearing 2 is relied on to meet the coaxality requirement of speed reducer output shaft 4 and bucket wheel axle 1, the utility model can connect bucket wheel reducer and bucket wheel axle 1, prevent from bucket wheel reducer from skidding off under axial thrust load effect to come off, thoroughly solve bucket wheel reducer and be separated with bucket wheel axle 1 fault come off.
