Description
Technical field
The utility model relates to a kind of sprocket wheel, is specifically related to a kind of external holder sprocket wheel.
Background technology
Holder sprocket wheel is the important spare part of Coal Chemical Industry dragveyer equipment, needs play the guiding role in dragveyer backhaul Chain conveyer process and bear certain load.Run continuously under the occasion of heavy duty because equipment is many, comparatively seriously, change frequent, service life is lower for holder sprocket wheel wheel body and the wearing and tearing of inner axle.
Prior art is in order to address this problem, and usually add a bearing in holder sprocket wheel inside, bearing both sides are provided with outside framework oil seal, can reduce the wearing and tearing of inner axle to a certain extent.But, the running part of the wheel body of prior art is arranged on wheel body inside usually, wheel body is in motion process, the deposits such as normal generation lime-ash, easily block the outside framework oil seal being positioned at the inner drive station of wheel body, reduce in oil sealing that lubricating oil is to the lubricant effect of bearing, the time one is long, the wearing and tearing of wheel body and inner axle still serious, change frequent.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of external holder sprocket wheel, has and prevents dust from entering oil sealing and bearing, and convenient interpolation bearing lubricates wet goods advantage, effectively can reduce the wearing and tearing of bearing and sprocket wheel, improve the service life of equipment.
A kind of external holder sprocket wheel described in the utility model, is characterized in that: comprise wheel shaft, is arranged on the bearing of axle ends and wheel shaft adaptation, be arranged on the wheel body on wheel shaft with bearing side by side; Described bearing radially outer is provided with bearing seat, and described bearing seat axial outer end is provided with end cap, and the inner is provided with rubber sheet gasket; Described bearing seat is through is provided with oil hole, and oil hole outside is provided with oil pot with screw cover; Oil sealing is provided with between described bearing and rubber sheet gasket.
As preferably, described wheel body and the connection mode of wheel shaft are that key is connected, and not easily loosen.
As preferably, described wheel body outer end is provided with wheel body circlip, plays buffer action.
As preferably, described end cap is mounted by means of bolts on bearing seat, is provided with wheel shaft circlip between described end cap and wheel shaft, effectively the impulse force of buffering wheel shaft opposite end lid.
As preferably, described rubber sheet gasket is mounted by means of bolts on bearing seat.
As preferably, described bearing is self-aligning roller bearing, can bear larger radial and axial load simultaneously.
As preferably, described oil sealing is two-lip seal, can play oil sealing and dust-proof effect simultaneously.
As preferably, described oil sealing arranged outside has transparent cover, can play dustproof effect.
Adopt technique scheme, by bearing and sprocket wheel wheel body being separated, operate simultaneously, the drive station of sprocket wheel is separated with wheel body, bearing and oil sealing are away from the wheel body producing lime-ash, and lime-ash not easily enters oil sealing, effectively can extend the service life of bearing and wheel shaft.
The beneficial effects of the utility model are, have and prevent dust from entering oil sealing and bearing, and convenient interpolation bearing lubricates wet goods advantage, effectively reduces the wearing and tearing of bearing and wheel shaft, improves the service life of equipment.

In figure, 1: wheel shaft, 2: bearing, 3: wheel body, 4: bearing seat, 5: end cap, 6: rubber sheet gasket, 7: oil pot with screw cover, 8: two-lip seal, 9: connecting key, 10: wheel body circlip, 11: bolt, 12: wheel shaft circlip, 13: transparent cover.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, the utility model is described in further detail.
A kind of external holder sprocket wheel, comprises wheel shaft 1, is arranged on the self-aligning roller bearing 2 of wheel shaft 1 end and wheel shaft adaptation, be arranged on the wheel body 3 on wheel shaft 1 with self-aligning roller bearing 2 side by side; Described self-aligning roller bearing 2 radially outer is provided with bearing seat 4, and described bearing seat 4 axial outer end is provided with end cap 5, and the inner is provided with rubber sheet gasket 6; Described bearing seat 4 is through is provided with oil hole, and oil hole arranged outside has oil pot with screw cover 7; Be provided with two-lip seal 8 between described bearing 2 and rubber sheet gasket 6, oil sealing and dust-proof effect can be played simultaneously; Two-lip seal 8 arranged outside has transparent cover 13, can play dustproof effect.
The fixed form of wheel body 3 and wheel shaft 1, for be connected by connecting key 9 key, is not easily loosened; Wheel body 3 outer end is provided with wheel body circlip 10; End cap 5 is fixedly mounted on bearing seat 2 by bolt 11, is provided with wheel shaft circlip 12 between end cap 5 and wheel shaft 1, effectively the impulse force of buffering wheel shaft 1 pair of end cap 5; Rubber sheet gasket 6 is mounted by means of bolts on bearing seat 2.
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.
