Description

Combined chain wheel

Technical field

The utility model relates to sprocket wheel, is specifically related to a kind of separable Combined chain wheel.

Background technique

Sprocket wheel is widely used in power-transmission system, common sprocket wheel comprises that the wheel body outer wall of hollow shaft shape has outstanding wheel rim, on wheel rim, there are the gear teeth, multiple common sprocket wheels need to coordinate transmission shaft and chain to use, after the long-time use of common sprocket wheel, can wear and tear or damage, need the sprocket wheel of dismantling and more renewing; But the sealing of common chain sprocket structure, must remove transmission shaft and relevant external means thereof while removing sprocket wheel together, complex operation step, working efficiency are low.

Model utility content

Technical problem to be solved in the utility model is to provide a kind of Combined chain wheel of being convenient to handling

For solving the problems of the technologies described above, the utility model provides a kind of Combined chain wheel, the wheel body outer wall of hollow shaft shape has outstanding wheel rim, on wheel rim, there are the gear teeth, wheel body comprises wheel seat and lower wheel seat, on upper wheel seat outer wall, have outstanding upper wheel rim, in lower wheel seat outer wall correspondence, there is outstanding lower rim wheel rim position, all has the corresponding gear teeth in upper wheel rim and lower rim;

Between upper wheel seat and lower wheel seat, be connected by least one group of connection part, described connection part comprises the connecting sheet of several identical wheel body end faces, between each connecting sheet and upper wheel seat and lower wheel seat, is connected.

Adopt after such structure, between upper wheel seat, lower wheel seat, connect by connection part, not only facilitate the installation or removal of this Combined chain wheel, and dismantle other external equipments while avoiding changing this Combined chain wheel.

Useful technique effect of the present utility model is: simple in structure, be convenient to dismounting, increase work efficiency.

On the upper wheel seat of this Combined chain wheel and the end face of lower wheel seat in the same side, have several tapped holes, on the connecting sheet of described connection part, the tapped hole of corresponding wheel body has some through holes, and the corresponding through hole through connecting sheet of some connecting bolts correspondence are connected with the tapped hole of upper wheel seat and the tapped hole of lower wheel seat.

Adopt after such structure, connecting sheet is by connecting bolt by relative fixing between upper wheel seat and lower wheel seat, i.e. simple in structure, easy disassembly, can repeatedly be used again.

In the upper wheel seat sidewall of this Combined chain wheel, have some upper fixed holes, have several lower fixed holes corresponding with upper fixed hole in lower wheel seat sidewall, some fixing bolts pass corresponding upper fixed hole and lower fixed hole respectively and correspondence coordinates with set screw nut; Adopt after such structure, fixing bolt coordinates with upper fixed hole and lower fixed hole, makes to be directly connected and fixed between wheel seat and lower wheel seat, increases steadiness and the Security of this Combined chain wheel.

Embodiment

As shown in Figures 1 to 4

This Combined chain wheel comprises wheel body and two groups of connection parts.

Wheel body comprises wheel seat 11 and lower wheel seat 12, and upper wheel seat 11 is all half hollow shaft shape with lower wheel seat 12, and upper wheel seat 11 is identical with the structure of lower wheel seat 12, and upper wheel seat 11 and lower wheel seat 12 coordinate formation hollow shaft shape wheel body.

On upper wheel seat 11 front and rear ends, evenly circle distribution has four tapped holes respectively, and there is outstanding upper wheel rim 11a at upper wheel seat 11 outer side wall middle parts, on upper wheel rim 11a, have the gear teeth 15, have keyway 11b on the inwall of upper wheel seat 11.

On lower wheel seat 12 front and rear ends, evenly circle distribution has four tapped holes respectively, and there is outstanding lower rim 12a at lower wheel seat 12 outer side wall middle parts, equally also have the gear teeth 15 on lower rim 12a.

In upper wheel seat 11 sidewalls, have two upper fixed hole 13a, in lower wheel seat 12 sidewalls, have two lower fixed hole 13bs corresponding with upper fixed hole 13a, two fixing bolts 14 are respectively through corresponding upper fixed hole 13a and lower fixing 13b hole and correspondingly coordinate with two set screw nuts 16;

Two groups of connection parts are separately positioned on the both sides, front and back of wheel body, every group of connection part comprises the connecting sheet 21 of two semicircle annulars, the structure of two connecting sheets 21 is identical, the each connecting sheet 21 wheel body end surface shape of coincideing, and on connecting sheet 21, the corresponding upper tapped hole position of wheel seat 11 and the tapped hole position of lower wheel seat 12 have four through hole 21a;

Each connecting sheet 21 coordinates with two tapped holes of upper wheel seat 11 and two tapped holes of lower wheel seat 12 respectively by four connecting bolts 22.

When installation, the upper wheel seat 11 of this Combined chain wheel and lower wheel seat 12 are arranged on transmission shaft, key between wheel seat 11 and transmission shaft is coordinated, then two groups of connection parts are fixing with upper wheel seat 11 and lower wheel seat 12 respectively, and connecting bolt 22 coordinates with corresponding tapped hole through the through hole 21a of connecting sheet 21 respectively; Pass upper fixed hole 13a and lower fixed hole 13b and coordinate with set screw nut 16 with two fixing bolts 14 again, completing the installation of this Combined chain wheel;

When changing or keeping in repair this Combined chain wheel damaging, first remove the connection between upper 11 times wheel seats 12 of wheel seat and connection part, then remove being connected between fixing bolt 14 and set screw nut 16, this Combined chain wheel is directly dismantled from transmission shaft.

Above-described is only a kind of mode of execution of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model principle; can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
