Description
Technical field
The utility model is related to gear technique field, specifically a kind of adjustable gear structure carried.
Background technology
Speed reducer is widely used in all trades and professions as a kind of deceleration or driving device, with the quick hair of China's industry
Exhibition, the requirement for speed reducer is higher and higher, and small size, large torque have become trend.To realize this purpose, Gear Planet Transmission is utilized
Principle development speed reducer it is more and more, unique transmission principle (power dividing summarizes output) can to greatest extent profit
It is deep to be liked by users with bulk to which volume is accomplished minimum.As the core component of speed reducer, gear plays
Very important effect, gear is put into above structure with then needing to solve the problems, such as to carry, how to ensure several groups of teeth
Wheel is synchronous to realize that the effect carried is then the most important thing.
As shown in Fig. 1-1, Fig. 1-2, No.1 gear 2 drives No. two gears 3 rotation for being sleeved on 4 shaft end of tooth shaft to carry out work(
Rate shunts, and tooth shaft 4 is rotated with the rotation of No. two gears 3, and several groups of tooth shafts 4 drive No. three gears being sleeved on output shaft simultaneously
1 rotation carries out power and summarizes, and is exported by output shaft.To realize above-mentioned power dividing, power remittance general purpose, first, necessary
Ensure that three No. two gears 3 synchronize the effect realized and carried, since No. two gears 3 are sleeved on the shaft end of tooth shaft 4, it is ensured that No.1
No. two gears 3 of 2 synchronous drive of gear, tooth shaft No. three gears 1 of 4 synchronous drive, then need to ensure each group coaxial mounted No. two
Gear 3 and tooth shaft 4 will be maintained at the same position, i.e., the keyway position on each rooted tooth axis will be fixed relative to the position of tooth,
The very difficult realization of this mode；It requires to be general key connection second, flat key connection is normal, the deviation being generally keyed is remote
More than the tolerance of gear engagement, therefore, driven gear transmission is connected by flat key and is difficult to meet the requirement carried, is waited
It improves.
Utility model content
The purpose of the utility model is to overcome the deficiencies in above-mentioned background technology, provide a kind of adjustable gear knot carried
Structure, the gear structure can effectively realize the load of each gear, and can prevent from overloading, and protect gear.
The technical solution of the utility model is：
A kind of adjustable detachable gear wheel structure carried, it is characterised in that：Including gear ring, core wheel, pressing plate and retaining spiral shell
Bolt；Core wheel is fixedly mounted on gear shaft, and gear ring is sleeved on core wheel, is matched for the conical surface between the endoporus of gear ring and the outer ring of core wheel
It closes, pressing plate is fixed on the end face of core wheel by Dogbolt and compresses gear ring.
Preferably, being fixedly connected by flat key between the core wheel and gear shaft.
The beneficial effects of the utility model：In the utility model, it is cone match between gear ring and core wheel, can adjusts several
The net synchronization capability of group gear ring, it is easier to realize the effect carried, gear ring and core wheel processing are simple and convenient, are reached in realization gear synchronous
Require have prodigious advantage to carrying；In addition, taking the connection type of such taper, overload protective function can be played, deceleration is worked as
When there are overload situations in machine, it is normal for will appear the failure phenomenon of broken teeth, after such connection type, the mistake of cone match
The amount of being full of is according to the power value transmitted, once the case where speed reducer overloads, gear and tooth shaft meeting are big because of the power transmitted
In the friction fit power of setting is to have skidded the phenomenon that, play the role of protection.The utility model overall structure is simple, adds
Work is relatively easy, when a certain parts damages without entire gear structure is needed to change, reduces use cost.
Description of the drawings
Fig. 1-1,1-2 are the gear structure schematic diagrams of existing speed reducer.
Fig. 2 is the schematic cross-sectional view of the utility model.
Specific implementation mode
To keep this full mold of greater clarity with new purpose, technical scheme and advantage, below by shown in the accompanying drawings
Specific embodiment describes the utility model.However, it should be understood that these descriptions are merely illustrative, and it is not intended to limit this reality
With novel range.In addition, in the following description, descriptions of well-known structures and technologies are omitted, to avoid unnecessarily mixing
Confuse the concept of the utility model.
As shown in Fig. 2, a kind of adjustable detachable gear wheel structure carried, including gear ring 5-2, core wheel 5-3, pressing plate 5-4 with
And Dogbolt 5-5.Core wheel is fixedly mounted on by flat key structure 5-6 on gear shaft 5-1, and core wheel is avoided to skid, gear ring suit
In the outer ring of core wheel, between the endoporus (bellmouth) of gear ring and the outer ring (male cone (strobilus masculinus)) of core wheel be cone match, if pressing plate by
A dry Dogbolt is fixed on the end face of core wheel and compresses gear ring.Degree is screwed by adjusting Dogbolt, pine can be adjusted
Or pressing plate is tightened, and change the pressure that pressing plate applies gear ring, to change the frictional force of cone match position, once speed reducer goes out
The case where now overloading, can be because the power transmitted be more than friction fit power the showing to have skidded set between core wheel and gear ring
As playing the role of protecting gear ring and gear shaft.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
