Description
Technical field
The utility model relates to gear technique field, specifically a kind of adjustable gear structure carried.
Background technique
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.For this purpose, Gear Planet Transmission is utilized
Principle development speed reducer it is more and more, unique transmission principle (power dividing summarizes output) can be sharp to greatest extent
It is deep to be liked by users with bulk to which volume is accomplished minimum.As the core component of speed reducer, gear is played
Very important effect, gear be put into above structure with then need to solve the problems, such as load, how to guarantee 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 power
It shunts, tooth shaft 4 is rotated with the rotation of No. two gears 3, and several groups of tooth shafts 4 drive No. three gears 1 being sleeved on output shaft simultaneously
Rotation carries out power and summarizes, and is exported by output shaft.To realize above-mentioned power dividing, power remittance general purpose, first, must protect
Three No. two gears 3 of card are synchronous to realize the effect carried, since No. two gears 3 are sleeved on the shaft end of tooth shaft 4, it is ensured that No.1 tooth
No. two gears 3 of 2 synchronous drive, tooth shaft No. three gears 1 of 4 synchronous drive are taken turns, then need to guarantee each group of coaxial mounted No. two tooth
Wheel 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, this
The kind very difficult realization of mode；It requires to be general key connection second, flat key connection is normal, the deviation being generally keyed is long-range
In the tolerance of gear engagement, therefore, driven gear transmitting is connected by flat key and is difficult to meet the requirement carried, waits to change
Into.
Utility model content
The purpose of the utility model is to overcome the deficiencies in above-mentioned background technique, 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:
The adjustable detachable gear wheel structure carried, it is characterised in that: including gear ring, tapered sleeve, core wheel, pressing plate and circle spiral shell
It is female；Core wheel is fixedly mounted on gear shaft, and gear ring is fixedly mounted on tapered sleeve, is cone between the inner hole of tapered sleeve and the outer ring of core wheel
Face cooperation, pressing plate are locked in the end face of core wheel by round nut and tapered sleeve are pressed on core wheel.
Preferably, being fixedly connected between the core wheel and gear shaft by flat key；Pass through flat key between gear ring and tapered sleeve
It is fixedly connected.
Preferably, the end thread of the round nut and core wheel cooperates, floor clip is equipped between round nut and pressing plate.
The utility model has the beneficial effects that be cone match between tapered sleeve and core wheel in the utility model, it is adjustable several
The net synchronization capability of group gear ring, it is easier to which the processing is simple for the effect that realization carries, gear ring and core wheel conveniently, reaches in realization gear synchronous
Require have very big 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 of transmitting
In setting friction fit power to have skidded the phenomenon that, play the role of protection.The utility model overall structure is simple, adds
Work is relatively easy, no replacement is required when a certain parts damages entire gear structure, reduces use cost.
Detailed description of the invention
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 embodiment
To keep this full mold more clear with new purposes, technical schemes and advantages, 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, the adjustable detachable gear wheel structure carried, including gear ring 5-2, tapered sleeve 5-9, core wheel 5-3, pressing plate 5-
4 and round nut 5-7.Core wheel is fixedly mounted on gear shaft by flat key structure, and gear ring is fixedly mounted on by flat key structure
It is cone match between the inner hole (taper hole) of tapered sleeve and the outer ring of core wheel on tapered sleeve, pressing plate is locked in core wheel by round nut
Tapered sleeve is simultaneously pressed on core wheel by end face.The cooperation of the end thread of the round nut and core wheel, is equipped between round nut and pressing plate
Floor clip 5-8.
The present embodiment carries out the synchronous adjustment of gear by round nut, passes through round nut after several groups of gear rings are adjusted
It is locked with stop washer, pressing plate is used to guarantee that gear ring and tapered sleeve do not generate axial float.Pass through the conical surface of tapered sleeve and core wheel
Cooperation, the net synchronization capability of several groups of gear rings is adjusted by nut, it is easier to realize the effect carried.Gear ring and core wheel are relatively only
Vertical, it is convenient that the processing is simple, requires have very big advantage realizing that gear synchronous reaches to carry.In addition, taking the company of such taper
Connect mode, overload protective function can be played, when there are overload situations in speed reducer, it is normal for will appear broken teeth failure it is existing
As after such connection type, the magnitude of interference of cone match is according to the power value transmitted (by adjusting the rotation of round nut
Tight degree can adjust pine or tighten pressing plate, change the pressure that pressing plate applies gear ring, to change the friction of cone match position
Power), once the case where speed reducer overloads, gear and tooth shaft can because the power of transmitting be greater than the friction fit power of setting to
The phenomenon that having skidded plays the role of protection.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
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.
