Known via above-mentioned technological scheme, compared with prior art, the utility model discloses a kind of speed reducer, comprise the oil-sealing arrangement of the mounting hole being arranged on casing and stretch out the transmission shaft of mounting hole, it also comprises and being set on transmission shaft, and seals the lining be arranged between oil-sealing arrangement and transmission shaft.By sheathed lining on transmission shaft in the application, directly contact with oil-sealing arrangement to make lining, transmission shaft is stoped to contact with oil-sealing arrangement, therefore, make oil-sealing arrangement to liner wear, namely effectively prevent transmission shaft and oil-sealing arrangement relative movement in speed reducer working procedure and make oil-sealing arrangement to the wearing and tearing of transmission shaft.When can direct more resleeve after liner wear, to ensure that speed reducer normally uses, in addition, also avoid the replacing to transmission shaft, because liner size is less, thus reduce cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiment of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the accompanying drawing provided.
The structural representation of Fig. 1 speed reducer disclosed in the utility model embodiment;
Fig. 2 is the partial enlarged drawing of A in Fig. 1;
Fig. 3 is arranged on the structural representation of the oil-sealing arrangement had on the transmission shaft of lining disclosed in the utility model embodiment.
Embodiment
Core of the present utility model is to provide a kind of speed reducer, avoids transmission shaft to wear and tear, to reduce costs.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-Figure 3, the utility model discloses a kind of speed reducer, comprise the oil-sealing arrangement 2 of the mounting hole being arranged on casing and stretch out the transmission shaft 1 of mounting hole, it also comprises and being set on transmission shaft 1, and seals the lining 3 be arranged between oil-sealing arrangement 2 and transmission shaft 1.By sheathed lining 3 on transmission shaft 1 in the application, directly contact with oil-sealing arrangement 2 to make lining 3, transmission shaft 1 is stoped to contact with oil-sealing arrangement 2, therefore, oil-sealing arrangement 2 pairs of linings 3 are worn and torn, namely effectively prevent transmission shaft in speed reducer working procedure 1 and oil-sealing arrangement 2 relative movement and make the wearing and tearing of oil-sealing arrangement 2 pairs of transmission shafts 1.Can direct more resleeve 3 after lining 3 weares and teares, to ensure that speed reducer normally uses, in addition, also avoid the replacing to transmission shaft 1, because lining 3 size is less, thus reduce cost.
In specific embodiment, lining 3 is set to wear-resisting alloy steel, to improve the wear resistance of lining 3, thus extends the working life of this lining 3, reduce costs.It will be appreciated by persons skilled in the art that in practice can according to the lining 3 of the maximum speed corresponding selection relative wear material of the transmission shaft 1 of speed reducer, and the lining 3 namely in the application is not limited to a kind of material.Further, also lining 3 and the wear resistance of the outer loop material of oil-sealing arrangement 2 connecting part can be set to higher with the wear resistance of loop material in transmission shaft 1 connecting part than lining 3, be set to be formed by the Material cladding of two kinds of different wear-resisting propertys by lining 3, to reduce the cost of production of lining 3.
By lining 3 and transmission shaft 1 interference fit in the application, to realize being tightly connected of lining 3 and transmission shaft 1.Merely provide a kind of Placement comparatively simply realizing lining 3 and be tightly connected with transmission shaft 1 herein; but; be not limited in this kind of Placement in the application, if can realize lining 3 seal with transmission shaft 1 and the Placement of synchronous axial system both ensureing all in protection domain.
In preferred embodiment, lining 3 is cylindrical sleeves, and this structure is simple, is convenient to processing.The core of the application is by the application of lining 3 between the transmission shaft 1 and oil-sealing arrangement 2 of speed reducer.
In further embodiment, this oil-sealing arrangement 2 comprises: the outer ring 21 of fitting with the inner wall sealing of the mounting hole of casing; Seal with lining 3 and fit, and cross section is the stop circle 22 of bending; Connect outer ring 21 and the fastener rings 23 stopping circle 22.Oil-sealing arrangement 2 structure of the application is simple, be easy to install, and sealing effect is good.In practice, also can need to select dissimilar oil-sealing arrangement and all in protection domain according to different.
Stop circle 22 in above-described embodiment specifically comprises near the internal resistance back-up ring of box house and the extrernal resistance back-up ring away from box house, and internal resistance back-up ring is connected by beam circle 24 with extrernal resistance back-up ring, and beam circle 24 is connected with fastener rings 23.The sealing effect that internal resistance back-up ring and extrernal resistance back-up ring can further improve oil-sealing arrangement 2 is set.Particularly, this internal resistance back-up ring is all contacted with lining 3 by its bottom corner portion with extrernal resistance back-up ring, and internal resistance back-up ring is all connected with beam circle 24 with the top of extrernal resistance back-up ring, to make to form space between internal resistance back-up ring and extrernal resistance back-up ring, stops fluid to be revealed further.
In order to optimize technique scheme further, will stop that the cross section of circle 22 is set to cambered surface, preferably arc surface, to prevent from stopping that circle 22 has wedge angle with the surface of contact of lining 3, thus reduce further the wearing and tearing to lining 3.
In this specification, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
