Description
Technical field:
The utility model relates to band crankshaft sprocket, belongs to the technical field of bearing.
Background technique:
Mechanical chain roller box bearing supports more of the prior art and the different bolt of bearing cap are fixed.When camshaft bearing is installed, first with bolt, camshaft bearing bush seat is arranged on chain-wheel box, and then with another group bolt, bearing cap is connected on bearing support, bearing process is installed and not only needs twice operation, twice centering, and bearing block bolt is to lower and upper assembling, is unfavorable for execute-in-place, the installation of whole bearing, operation is loaded down with trivial details, and the difficulty of in-site installation and dismounting is comparatively large, reduces the validity of on-the-spot as installed, add labour cost, reduce efficiency of assembling.
Model utility content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide band crankshaft sprocket.
Of the present utility model, it comprises bearing cap, bearing support, thrust ring, bearing shell, pad, cylindrical pin with internal thread, stud, tightening nut and screw, bearing support is arranged with pad, two bearing shells are provided with between bearing cap and bearing support, bearing cap, bearing support and pad are fixedly connected on chain-wheel box from top to down by stud and tightening nut, bearing cap is fixedly connected with by cylindrical pin with internal thread with bearing support, the inner peripheral surface of bearing support and bearing cap is distributed with four thrust rings, thrust ring is fixed by screw.
The beneficial effects of the utility model: it can overcome the drawback of prior art, be connected on chain-wheel box by stud and tightening nut by disposable to bearing cap, bearing support and pad, eliminate the once mounting in original structure and a centering operation, simplify the structure of chain-wheel box, facilitate casting and the processing of sprocket wheel casing.
Accompanying drawing illustrates:
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is the structural representation of the utility model band crankshaft sprocket.
1-bearing cap, 2-bearing support, 3-thrust ring, 4-bearing shell, 5-pad, 6-cylindrical pin with internal thread, 7-stud, 8-tightening nut and 9-screw.
Embodiment:
As shown in Figure 1, this embodiment is by the following technical solutions: it comprises bearing cap 1, bearing support 2, thrust ring 3, bearing shell 4, pad 5, cylindrical pin with internal thread 6, stud 7, tightening nut 8 and screw 9, bearing support 2 is arranged with pad 5, two bearing shells 4 are provided with between bearing cap 1 and bearing support 2, bearing cap 1, bearing support 2 and pad 5 are fixedly connected on chain-wheel box from top to down by stud 7 and tightening nut 8, bearing cap 1 is fixedly connected with by cylindrical pin with internal thread 6 with bearing support 2, the inner peripheral surface of bearing support 2 and bearing cap 1 is distributed with four thrust rings 3, thrust ring 3 is fixed by screw 9.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
