Abstract
The utility model proposes a kind of rice-pulling chain wheel bearing, in order to solve the problem that in prior art, corn machine ceding of Taiwan gear-box rice-pulling chain wheel bottom end bearing is dust-proof and sealing effectiveness is bad.A kind of rice-pulling chain wheel bearing, comprise casing, sprocket shaft opening is provided with above casing, be provided with a sprocket shaft in sprocket shaft opening, on sprocket shaft, cover has sprocket wheel, and sprocket wheel is positioned at the outside of casing, multiple ball bearing is provided with in casing, ball bearing is distributed in the both sides of sprocket shaft, is provided with dust cap between sprocket wheel and casing, and the upper end of sprocket shaft is provided with platen nut.This rice-pulling chain wheel bearing increases dust cap intensity, and dust cap coordinates with the periphery that casing is processed, and reduces fit clearance, and coordinate opening surface downward, dust not easily enters and improves dust-proof effect, gear breaking rate is declined a lot.
Description
Technical field
The utility model relates to agricultural mechanical field, refers to a kind of rice-pulling chain wheel bearing especially.
Background technology
At present, corn machine ceding of Taiwan gear-box rice-pulling chain wheel bottom end bearing needs protection, and originally adopt dust ring opening upwards, dust-proof effect is poor, causes bearing failure after bearing sealed ring breakage.
Therefore, a kind of rice-pulling chain wheel bearing of dust-proof and good sealing effect is needed now badly.
Utility model content
The utility model proposes a kind of rice-pulling chain wheel bearing, solve the problem that in prior art, corn machine ceding of Taiwan gear-box rice-pulling chain wheel bottom end bearing is dust-proof and sealing effectiveness is bad.
The technical solution of the utility model is achieved in that a kind of rice-pulling chain wheel bearing, comprise casing, sprocket shaft opening is provided with above described casing, be provided with a sprocket shaft in described sprocket shaft opening, on described sprocket shaft, cover has sprocket wheel, and described sprocket wheel is positioned at the outside of described casing, multiple ball bearing is provided with in described casing, described ball bearing is distributed in the both sides of described sprocket shaft, is provided with dust cap between described sprocket wheel and described casing, and the upper end of described sprocket shaft is provided with platen nut.
As one preferred embodiment, the number of described ball bearing is four.
As one preferred embodiment, the both sides of described sprocket shaft are distributed with two ball bearings respectively.
As one preferred embodiment, the shape of described sprocket shaft opening is circular, the size of described dust cap and the periphery of described sprocket shaft opening suitable.
As one preferred embodiment, the cooperation opening surface of described dust cap is arrange downwards.
As one preferred embodiment, sealing ring is provided with between two adjacent described ball bearings.
As one preferred embodiment, trunnion shaft is provided with between described sealing ring.
After have employed technique scheme, the beneficial effects of the utility model are: adopt novel structure dust-proof, increase dust cap intensity, dust cap coordinates with the periphery that casing is processed, and reduce fit clearance.Coordinate opening surface downward, dust not easily enters and improves dust-proof effect.Change backgear fracture rate declines a lot, does not almost have phenomenon of rupture to occur.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical 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 embodiments more 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 these accompanying drawings.
Fig. 1 is a kind of embodiment of the utility model rice-pulling chain wheel bearing.
In figure, 1-casing; 2-sprocket shaft opening; 3-sprocket shaft; 4-sprocket wheel; 5-ball bearing; 6-dust cap; 7-platen nut; 8-sealing ring; 9-trunnion shaft.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical 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, a kind of rice-pulling chain wheel bearing, comprise casing 1, above casing 1, be provided with sprocket shaft opening 2, in sprocket shaft opening 2, be provided with a sprocket shaft 3, on sprocket shaft 3, cover has sprocket wheel 4, sprocket wheel 4 is positioned at the outside of casing 1, and be provided with multiple ball bearing 5 in casing 1, ball bearing 5 is distributed in the both sides of sprocket shaft 3, be provided with dust cap 6 between sprocket wheel 4 and casing 1, the upper end of sprocket shaft 3 is provided with platen nut 7.
The number of ball bearing 5 is four.
The both sides of sprocket shaft 3 are distributed with two ball bearings 5 respectively.
The shape of sprocket shaft opening 2 is circular, the size of dust cap 6 and the periphery of sprocket shaft opening 2 suitable.
The cooperation opening surface of dust cap 6 is arrange downwards.
Sealing ring 8 is provided with between two adjacent ball bearings 5.
Trunnion shaft 9 is provided with between sealing ring 8.
The operation principle of this rice-pulling chain wheel bearing is: adopt novel structure dust-proof, increase dust cap intensity, dust cap coordinates with the periphery that casing is processed, and reduces fit clearance.Coordinate opening surface downward, dust not easily enters and improves dust-proof effect.Change backgear fracture rate declines a lot, does not almost have phenomenon of rupture to occur.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
