Abstract
The utility model relates to a ratchet gear wheel, which comprises a ratchet wheel and a gear wheel which are manufactured on the same wheel, wherein half part of the cross section of wheel is the ratchet wheel, while the other half part of the cross section of wheel is the gear wheel; and the ratchet wheel and the gear wheel are made into a whole and coaxial. In the utility model, the gear wheel and the ratchet wheel are made into one part, the ratchet gear wheel has a simpler structure than the current commonly used ratchet wheel for realizing unidirectional transmission, and as the toothed curves of the wheel teeth of the ratchet wheel and the gear wheel are the same, machining the ratchet gear wheel is equal to machining a thicker gear wheel. Compared with gear wheel and ratchet wheel which are machined separately, the ratchet gear wheel has the advantages that: the machining amount is reduced; and the strength of the thicker ratchet gear wheel is higher. When the ratchet gear wheel works, a pawl is meshed with the ratchet wheel while the gear for transmitting torque wheel rotates in a certain direction; while when the gear wheel rotates in an opposite direction, a shaft idles, so unidirectional transmission is realized. In the utility model, one part conducts the combined functions of two parts, namely, the ratchet wheel and the gear wheel.
Description
Technical field
The utility model belongs to field of mechanical manufacture technology, is specifically related to a kind of ratchet wheel.
Background technique
In mechanical transmission fields, in order to realize unidirectional transmission, ratchet is one of a kind of mechanical parts commonly used.At present, in gear-driven transmission system,, be on certain axle of Transmitted chains, to add a ratchet mostly as realize unidirectional transmission with ratchet.When the tooth of ratchet and ratchet meshes, carry-over moment, when opposite spin, the tooth of ratchet and ratchet breaks away from, axle idle running.Can realize unidirectional transmission though do like this, increase part, therefore also increase the size of cost and mechanism.
In view of this, seek a kind of ratchet wheel and become pursuing one's goal of these those skilled in the art.
The model utility content
Task of the present utility model provides a kind of ratchet wheel, and it has solved above-mentioned existing in prior technology problem, and ratchet and Gear Processing are made part on same wheel, realizes unidirectional transmission, has compact structure, easy to process, advantage such as intensity is good.
Technical solution of the present utility model is as follows:
A kind of ratchet wheel comprises ratchet and the gear of processing and fabricating on same wheel, and the half side part in this wheel cross section is a ratchet, and half side part is a gear in addition, and ratchet and gear are made one; Described ratchet is coaxial with gear.
Be equipped with the gear teeth that process simultaneously on described ratchet and the gear.
Described ratchet is consistent with the tooth-formation of gear curve.
The tooth depth of described ratchet is less than the tooth depth of gear.
Described ratchet engaged has the ratchet of single pawl.
Described ratchet engaged has the ratchet of two pawls.
Described ratchet engaged has the ratchet of three pawls.
The utility model is taked certain gear in the Transmitted chains and ratchet are merged, and makes a part, is referred to as ratchet wheel.When gear during along the rotation of certain direction, the tooth of ratchet and ratchet meshes, carry-over moment; When the gear opposite spin, axle idle running, thus realize unidirectional transmission.Like this, part plays the effect of ratchet and two parts of gear simultaneously.
The utility model makes it compared with prior art owing to adopted above technological scheme, and the utility model is made a part with gear and ratchet, realizes that with ratchet the mode of unidirectional transmission compares with at present normally used, and its structure is compact more; Simultaneously, ratchet adopts identical tooth curve with the gear teeth of gear, and like this, the processing ratchet wheel just is equivalent to process the thickness gear of some greatly.The utility model is compared with gear, the ratchet of separate machined, has reduced amount of finish; Because the thickness of ratchet wheel is big, its intensity is better again.
Description of drawings
Fig. 1 is the plan view of a kind of ratchet wheel of the present utility model.
Fig. 2 is the side view by ratchet wheel shown in Figure 1.
Fig. 3 is the structural representation that has the ratchet of two pawls in Fig. 1 ratchet wheel.
Reference character:
1 is ratchet, and 2 is ratchet, and 3 is gear, and 4 are the ratchet with two pawls.
Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Referring to Fig. 1 and Fig. 2, the utility model provides a kind of ratchet wheel, and it is made up of ratchet 2 and gear 3, ratchet 2 and gear 3 processed being produced on the same wheel.The half side part in this wheel cross section is a ratchet 2, and half side part is a gear 3 in addition, and ratchet 2 is made one with gear 3.Simultaneously, ratchet 2 is coaxial with gear 3.
As shown in Figure 2, on ratchet 2 and gear 3, be equipped with the gear teeth that process simultaneously.The tooth depth of ratchet 2 is less than the tooth depth of gear 3.
As shown in fig. 1, ratchet 2 is consistent with the tooth curve of gear 3.
Press actual demand, ratchet 2 engagements have the ratchet 1 of single pawl; Referring to Fig. 3, ratchet 2 engagements have the ratchet 4 of two pawls; Ratchet 2 also can mesh the ratchet 4 that has three pawls; Perhaps ratchet 2 engagements have the more ratchet 4 of multijaw.
The actual use condition of ratchet wheel of the present utility model is as follows:
Ratchet and these two parts of gear of using in traditional unidirectional transmission are combined, make a part.In Transmitted chains, it can play the effect of gear and ratchet simultaneously.
As shown in Figure 2, ratchet and gear are made into a part, and a half thickness of this part is a gear, and second half thickness is ratchet.The shape of the tooth of ratchet is substantially the same with the shape of the tooth of gear, and their difference only is that the height of tooth of ratchet is little than the tooth of gear.Be to help processing as the shape of the tooth of ratchet why, so just can when adding work gear, process the tooth of ratchet with the shape of the tooth of gear.
Concrete processing method is the thickness that increases gear, and half of this wheel thickness made gear, is used for original gear transmission, and second half of this wheel thickness made ratchet, realizes unidirectional transmission with it.On work efficiency, process a ratchet wheel and then be equivalent to process a gear that thickness is thicker slightly.Answer self-locking conditions satisfied here, when the principle of height of determining the tooth of ratchet is tooth peak place and ratchet engagement.
A ratchet and ratchet engaged are only arranged among Fig. 1, can adopt two or more ratchets as required during actual the use.Each ratchet can have a pawl, and two pawls among Fig. 3 also can be arranged, and a plurality of pawls can also be arranged.
In summary, the utility model is made a part with gear and ratchet, realizes that with ratchet the mode of unidirectional transmission compares with at present normally used, and its structure is compact more; Simultaneously, ratchet adopts identical tooth curve with the gear teeth of gear, and like this, the processing ratchet wheel just is equivalent to process a gear that thickness is thicker slightly.The utility model is compared with gear, the ratchet of separate machined, has reduced amount of finish; Because the thickness of ratchet wheel is big, its intensity is better again.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim the variation of the foregoing description, modification etc.
