Abstract
The invention provides a gearbox for a scraper conveyor. The gearbox comprises a gearbox body, an input shaft and an output shaft. The input shaft is arranged on the gearbox body transversely, and the output shaft is arranged on the gearbox body longitudinally. A jointing plate is sleeved on the outer side of the input shaft, at least two bearings are arranged between the jointing plate and the input shaft, and both sides of the outmost bearing are provided with sealing surfaces. Two ends of the output shaft are flush with the upper side and the lower side of the gearbox body, and glands capable of sealing the two ends of the output shaft are arranged on the surface of the gearbox body. Compared with the prior art, the gearbox for the scraper conveyor has the advantages of reasonable design, simple structure, convenience in use, high practicability and promotion easiness; the sealing performance of the input shaft is improved effectively, then safety performance thereof is improved, and the problem of oil leakage on the jointing face is solved thoroughly.
Description
Technical field
The present invention relates to the gear case technology that a kind of scraping transporter is used, specifically a kind of scraping transporter gear case of simple in structure, favorable sealing property.
Background technology
In the Coal Transportation process of prior art, need to use scraping transporter, and a significant points of scraping transporter is gear case, current gear case comprises an axle and two axles, be input shaft and output shaft, between input shaft and the casing of gear case, be provided with a plurality of bearings, owing to there is gap between bearing and input shaft, cause sealing effectiveness poor, leakage of oil point is many, and this axle bearing collocation is unreasonable simultaneously; Output shaft stretches out gear case, and its sponson is used for tight sprocket wheel, tension chain, the easy like this poor safety performance that causes whole gear case, the service life of shortening gear case.
Summary of the invention
Technical assignment of the present invention is to solve the deficiencies in the prior art, and a kind of scraping transporter gear case that is easy to use, favorable sealing property is provided.
Technical scheme of the present invention realizes in the following manner, this scraping transporter gear case, its structure comprises gear case body for slat conveyer, be arranged on horizontal input shaft on gear case body and output shaft longitudinally, the outside socket of described input shaft is provided with in conjunction with panel, this is in conjunction with being provided with at least two bearings between panel and input shaft, wherein outermost bearing both sides are provided with sealing surface; The two ends of described output shaft are provided with the surface mutually concordant and gear case body, both sides up and down of gear case body can be by the gland of its both ends sealing.
In this technical scheme, by the bearing arrangement that adopts two sides all to seal, can effectively improve the one axle bearing sealing of slat conveyer gear case, the bearing felt of input shaft, improves a sealing performance; Output shaft no longer stretches out gear case, improves the general safety performance of gear case, and then extends the service life of gear case.
As preferably, sealant sealing is all passed through in the junction between junction, bearing and input shaft between described combination panel and bearing.
Further, described sealant is that model is the high-performance plane sealant of TS515.Maximum filling gap 0.25 ㎜ of sealing glue, the larger sealing effectiveness of pressure is better.
The beneficial effect that the present invention compared with prior art produced is:
Scraping transporter of the present invention has simple in structure, easy to use, the feature such as be skillfully constructed with gear case, by effective slat conveyer gearbox input shaft bearing felt that improves, improves input shaft sealing property; Structure by transformation output shaft, improves its safety performance; High-performance plane sealant is used in faying face sealing, has thoroughly solved faying face oil leakage phenomenon, and integral structure is cheap for manufacturing cost, practical, is easy to promote.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Mark in accompanying drawing represents respectively:
1, gear case body, 2, input shaft, 3, in conjunction with panel, 4, output shaft, 5, bearing, 6, sealing surface, 7, gland, 8, sealant.
The specific embodiment
Below in conjunction with accompanying drawing, scraping transporter of the present invention is described in detail below with gear case.
As shown in Figure 1, this scraping transporter gear case, its structure comprises gear case body 1 for slat conveyer, be arranged on horizontal input shaft 2 on gear case body 1 and output shaft 4 longitudinally, described input shaft 2 outside sockets are provided with in conjunction with panel 3, this is in conjunction with being provided with at least two bearings 5 between panel 3 and input shaft 2, and wherein outermost bearing 5 both sides are provided with sealing surface 6; The two ends of described output shaft 4 are provided with the surface mutually concordant and gear case body 1, both sides up and down of gear case body 1 can be by the gland 7 of its both ends sealing.
Junction between junction between described combination panel 3 and bearing 5, bearing 5 and input shaft 2 all seals by sealant 8.
Described sealant 8 is that model is the high-performance plane sealant of TS515.
Embodiment: input shaft 2 and in conjunction with using two bearings between panel 3, inboard bearing is 7309AC bearing, outer bearing is that 6309-2RZ profile shaft holds, this can bear footpath, axial connected load, realizes the two-way axial location of doing.This class bearing also has certain aligning ability, and actv. has solved an axle leakage of oil.The tight sprocket part of output shaft 4 is removed, directly with gland, seal, solved a serious leakage of oil point, also solved the potential safety hazard of using tight sprocket wheel tensioning scraper chain crowbar to injure personnel simultaneously.
Except the technical characterictic described in specification sheets, be the known technology of those skilled in the art.
