Abstract
The utility model belongs to the technical field of mechanical transmission, and particularly relates to a motor cycle chain tensioning adjusting device which solves the problem that an existing motor cycle chain becomes long and is loosened after working for a long time, and transmission effect becomes bad. The motor cycle chain tensioning adjusting device is arranged on a cycle frame between a front wheel and a back wheel of a motor cycle, and transmission between the front wheel and the back wheel is achieved through a chain. The tensioning adjusting device comprises a tensioning wheel, an adjusting seat and an adjusting mechanism. The adjusting seat and the adjusting mechanism are fixedly arranged on the cycle frame. An adjusting sliding groove which is arranged with a chain adjusting section in a staggering mode is formed in the adjusting seat. An adjusting bolt is arranged in the adjusting sliding groove and is in transmission connection with the tensioning wheel. The tensioning wheel presses against the chain. The adjusting mechanism is used for driving the adjusting bolt and the tensioning wheel to move along the adjusting sliding groove. The motor cycle chain tensioning adjusting device can effectively adjust the tensioning degree of the chain through the position relation of the tensioning wheel on the sliding groove, and meanwhile stability is enhanced, and service life of the chain is prolonged.
Description
Technical field
The utility model belongs to the mechanical transmissioning technology field, relates to the adjusting of transmission device, particularly a kind of motorcycle chain tightening regulator.
Background technology
The chain transmission is one of modal type of drive in the present mechanical equipment, and the chain-drive figure is seen everywhere in the equipment such as weight-lifting equipment, parking apparatus, passenger-cargo, elevator, automobile, bicycle, toy or mechanism.Along with chain-drive frequently uses, because the problem that the wearing and tearing of chain, sprocket wheel cause is also more and more, plastic deformation and then elongated can occur because chain is long-time after stressed, thereby also can jump tooth when serious, the phenomenon of falling chain causes transmission process to interrupt even have an accident.Present 4 stroke motorcycle moves approximately 10,000 kilometers, and gimmal just elongates, becomes flexible, and causes bob, and cylinder head, cylinder body are produced friction, causes driving engine noise to occur, and gimmal has just been scrapped, and must change gimmal, and noise could be eliminated.Because now the gimmal quality is uneven on the market, a lot of customers not understand, most of gimmal on being installed to motor bike after, travel three, 4,000 kilometers and just easily elongate, friction cylinder head, cylinder body, and noise appears, bring many troubles and economic loss to the customer.
Elongate problem in order to solve chain-loose, eurypalynous chain stretching device has appearred on the market being permitted, be that the mechanism of CN201053481Y a kind of chain stretching device by name is that we are now more common such as publication number, it comprises that power wheel, tensioner arm, tension spring, rotating shaft, hold-down arm form.Hold-down arm is fixed on the vehicle frame by hind axle, one end of tensioner arm is connected with hold-down arm by rotating shaft, the other end is installed a cylindrical rubber power wheel, and this power wheel is contacted with chain, when chain generation degree of tension changes, tension spring just can drive tension wheel and automatically adjust chain, makes chain be in all the time tensioning state.But this device is in fact take any as the support center, tension wheel can have a down dip and swing in the process that chain spurs fast, drive the continuous motion of spring, actually for accelerating to weaken the spring deformability, also be to accelerate chain to fluff and constantly keep chain to be in tensioning state with tension wheel, elongated major cause, therefore this device can use on the less demanding equipment of some low speed, such as looking like bicycle etc., and the high-speed chain rotating mechanism has excessive impact for the amplitude of chain vibrations and the elastic deformation parameter of spring, and how regulating tension wheel also needs row to consider with cooperating of chain again.
Summary of the invention
The purpose of this utility model is for existing the problems referred to above, and proposed a kind of simple in structure, reliable, installation and maintenance are convenient can adjust at any time chain tension degree and the strong a kind of motorcycle chain tightening regulator of applicability.
The purpose of this utility model can realize by following technical proposal:
A kind of motorcycle chain tightening regulator, be arranged on the vehicle frame between two wheels of motor bike front and back, between the front and back wheel by chain gear, it is characterized in that, described tightening regulator comprises tension wheel, is fixedly installed on adjustment seat and regulating mechanism on the vehicle frame, offer on the adjustment seat with chain the adjusting chute that is crisscross arranged of the section of accent, regulate in the chute and be provided with adjusting bolt, adjusting bolt and tension wheel are rotationally connected, tension wheel is pressed against on the chain, and described regulating mechanism is for driving adjusting bolt and tension wheel along regulating runner movement.
In above-mentioned a kind of motorcycle chain tightening regulator, described regulating mechanism comprises adjusting yoke, one of adjusting yoke is connected with adjusting bolt, the other end passes the baffle plate on the adjustment seat, being threaded on the adjusting yoke was located at the nut of baffle plate both sides in two minutes, and above-mentioned adjusting yoke and tension wheel divide and be located at the adjustment seat both sides.
In above-mentioned a kind of motorcycle chain tightening regulator, offer annular groove on the described tension wheel, the width of groove is greater than the width of chain.
Compared with prior art, this device is by the effective degree of tension of adjusting chain of the position relationship of tension wheel on sliding tray, the chiasma type of sliding tray and chain arranges the enhancing degree of regulation, the locate mode of sliding tray and thread has reduced beating of tension wheel simultaneously, strengthen stability, make chain when stretching, reduce the time length of tensioning state, increased the service life of chain.

The specific embodiment
Shown in Fig. 1～2,
A kind of motorcycle chain tightening regulator, be arranged on the vehicle frame 11 between two wheels of motor bike front and back, pass through chain 12 transmissions between front and back driving wheel 2 and the flower wheel 7, tightening regulator comprises tension wheel 10, be fixedly installed on adjustment seat 5 and adjusting yoke 6 on the vehicle frame 11, offer on the adjustment seat 5 with chain 12 the adjusting chute 4 that is crisscross arranged of the section of accent, regulate in the chute 4 and be provided with adjusting bolt 3, adjusting bolt 3 is rotationally connected with tension wheel 10, between be equipped with bearing 9, be pressed in outside the tension wheel 10 (such as Fig. 3) on the chain 12, adjusting yoke 6 and tension wheel were located at adjustment seat 5 both sides in 10 minutes, one of adjusting yoke 6 is connected with adjusting bolt 3, the other end passes the baffle plate 51 on the adjustment seat 5, being threaded on the adjusting yoke 6 was located at the nut 13 of baffle plate 51 both sides in two minutes, and the nut 13 that is located at baffle plate 51 both sides by adjusting can make adjusting yoke 6 move along regulating chute 4.Offer annular groove 10a on the tension wheel 10, the width of groove 10a is greater than the width of chain 12.
Excessive wearing and tearing and stretching can make body become slack when chain 12 rotated, affect the effect of transmission, tensioning function by tension wheel 10 can heavily make chain 12 tensions, but installation 10 a period of times of tension wheel also can relax again with rear chain 12, therefore need pulling adjusting yoke 6 that tension wheel 10 is moved up, be the x-shape interlock setting owing to regulating chute 4 with chain 12 again, so tension wheel 10 is to the close movement travel of chain 12 directions much smaller than it along the sliding distance of regulating chute 4, the tensile force degree of regulation of chain 12 is high.
Basic structure is identical with embodiment 1, and its difference is, as shown in Figure 4, is pressed on the chain 12 in the described tension wheel 10, and the sense of motion of adjusting yoke 6 is opposite with embodiment 1.
