Abstract
A kind of freewheel clutch of the utility model, is related to mechanical transmission fields, is formed by actively circle, roller, from moving-coil, mounting flange, hole with back-up ring, baffle plate, shaft block ring, deep groove ball bearing；It is characterized in that：When power inputs from power transmission shaft, actively circle when rotating counterclockwise is driven, actively circle, roller and wedging is formed from moving-coil three, closes clutch, torque is transferred to from moving-coil by active circle；When active circle is rotated clockwise or stopped, roller moves to wedge cavities centre position, and now clutch disconnects, and unpowered transmission, runs out of steam, can freely rotate from moving-coil.This clutch configuration is simple, and easy processing assembling, cost is low, and work is light, and service life length, noise caused by work is low, is widely used in machine driving.
Description
Technical field
It the utility model is related to technical field of mechanical transmission, more particularly to a kind of overdrive clutch being applied in machine driving
Device.
Background technology
At present, in machine driving roller-type overrunning clutch using fairly common.But existing most of overdrive clutch
Device transmission torque is small, and shake, unstable phenomenon are produced when clutch and axle are combined, while produces very big noise, most
Serious wear afterwards, causes to fail, and inconvenience is brought to use.The short life of these clutches, component are also complicated, it is difficult to processing and
Assembling.
The content of the invention
The purpose of this utility model is to provide a kind of big transmission torque, smooth engagement, service life is long, noise is low, departs from
Transmission device convenient, component is simple, easy processing assembles.
A kind of freewheel clutch transmission device, including mounting flange (1), hole back-up ring (2), from moving-coil (3), baffle plate (4),
Actively circle (5), shaft block ring (6), roller (7), deep groove ball bearing (8).
Described active circle (5) is monoblock type ratchet structure (external tooth form is as shown in Figure 3), passes through key and propeller shaft couplings.
Described baffle plate (4) is arranged on the both sides of roller, prevents roller from coming off.
Described hole is mounted in bearing both ends with back-up ring (2), plays axially position.
Described shaft block ring (6) is to carry out axially position to baffle plate.
The utility model has advantages below compared with prior art：
1. the utility model freewheel clutch, is widely used in machine driving, and it is big to transmit torque, smooth engagement.
2. each component in clutch is all simple, easy processing assembling.And composition clutch member is few, convenient disassembly.
3. power transmission shaft and clutch disengaging are light, noise is low, service life length.

Fig. 1 is front view of the present utility model (sectional view).
Fig. 2 is left view of the present utility model (Local map).
Fig. 3 is the external tooth form figure of active circle (5) of the present utility model.
In figure：1-mounting flange；2-hole back-up ring；3-from moving-coil；4-baffle plate；5-actively enclose；
6-shaft block ring；7-roller；8-deep groove ball bearing.
Embodiment
A kind of freewheel clutch transmission device, including mounting flange (1), hole back-up ring (2), from moving-coil (3), baffle plate (4),
Actively circle (5), shaft block ring (6), roller (7), deep groove ball bearing (8) etc..
Described active circle (5) is monoblock type ratchet structure (concrete structure is as shown in Figure 3), is joined by key and power transmission shaft
Connect, power is passed into actively circle (5).
It is described to have roller (7) from moving-coil (3) and actively between circle (5), and there are baffle plate (4), baffle plate (4) in roller (7) both ends
Both ends are equipped with shaft block ring (6), make above-mentioned component assembly into a sets of transmission mechanism；Further, the transmission mechanism, passes through depth
On ditch ball bearing (8) mounting flange mounted externally (1), deep groove ball bearing (8) both ends are equipped with hole with back-up ring (2).
The positioning hole and fastening thread hole having from moving-coil (3) for coupling executive item (such as mechanical arm etc.).
Described freewheel clutch transmission device, when power inputs from power transmission shaft, actively circle (5) rotates counterclockwise for drive
When, actively enclose (5), roller (7) and form wedging from moving-coil (3) three, close clutch, torque is transmitted by active circle (5)
Extremely from moving-coil (3)；When active circle (5) is rotated clockwise or stopped, roller (7) moves to wedge cavities centre position, now clutch
Device disconnects, and unpowered transmission, runs out of steam, can freely rotate from moving-coil (3).
Described above is not limitation of the utility model, and the utility model is also not limited to the example above, this technology neck
The variations, modifications, additions or substitutions that the those of ordinary skill in domain is made in essential scope of the present utility model, fall within this
The protection domain of utility model.
Claims (3)
1. a kind of freewheel clutch, including：Actively circle (5), it is described to have from moving-coil (3) and actively between circle (5) from moving-coil (3)
Roller (7), and there is a baffle plate (4) at roller (7) both ends, baffle plate (4) both ends are equipped with shaft block ring (6), actively enclose (5) by key with
Propeller shaft couplings, make above-mentioned component assembly into a sets of transmission mechanism；An above-mentioned sets of transmission mechanism is pacified by deep groove ball bearing (8)
On external stability flange (1), deep groove ball bearing (8) both ends are equipped with hole with back-up ring (2).
2. freewheel clutch according to claim 1, it is characterised in that：Actively circle (5) is integral formula ratchet structure, leads to
Cross key and propeller shaft couplings.
3. freewheel clutch according to claim 1, it is characterised in that：When power inputs from power transmission shaft, drive is actively enclosed
(5) when rotating counterclockwise, actively enclose (5), roller (7) and from moving-coil (3) three formed wedging, close clutch, torque by
Actively circle (5) is transferred to from moving-coil (3)；When active circle (5) is rotated clockwise or stopped, roller (7) is moved among wedge cavities
Position, now clutch disconnection, unpowered transmission, runs out of steam from moving-coil (3), can freely rotate.
