Description

The coupling type clutch

Technical field

The utility model relates to a kind of clutch, particularly the clutch of hand tractor and other machinery supports use.

Background technique

Hand tractor of the prior art often is used some other machineries according to different use occasions, as rotary cultivator, ditching machine etc., these machineries need hand tractor that power is provided, at hand tractor with need to be provided with clutch accordingly between other machineries, existing clutch mainly comprises the colyliform clutch main body of hollow, clutch main body outer round surface is provided with belt grooves, clutch main body both sides are provided with the cavity in the end cap closed clutch main body, wherein a side end cap can form with clutch main body integrally casting, the clutch main body axis is provided with a main shaft that is installed in the bearing support, two end cap is provided with bearing, described bearing housing is contained on the main shaft, be set with axle sleeve on the main shaft between the two bearings, the section of axle sleeve and main shaft is the spline-shaped that cooperatively interacts, also be provided with in the clutch main body and be sleeved on the outer driving wheel base of axle sleeve, the driving wheel backrest of driving wheel base periphery and the setting of clutch main body inner circumference is coupled, circumferentially be evenly equipped with at least two supporting bases near on the end cap of bearing support one side, each supporting base and disengaging pawl middle part are hinged, each disengaging pawl one end is conflicted in a side that is set in the release bearing on the main shaft, between release bearing and bearing support, be set with the male part that two working surfaces are obliquely installed and match on the main shaft, one of them male part side is connected with pull bar through connecting rod, each disengaging pawl the other end is respectively equipped with the motion bar that vertically passes end cap, motion bar is connected with the driving wheel base, be provided with spring between driving wheel base and the close end cap of bearing support one side, the driving wheel base is provided with a friction plate, also be set with the friction wheel that a surface is provided with friction plate on the axle sleeve, be provided with follower between friction wheel and the driving wheel base, follower and axle sleeve fix; During work, the pulling pull bar drives one of male part and rotates an angle, distance between the end face of two male parts increases or reduces, when distance reduced, release bearing promoted the disengaging pawl action, and acting force of the spring promotes the driving wheel base, make friction plate touch follower, and then it is close to friction wheel to promote follower, behind follower and friction wheel, through the clutch main body and the power that comes can pass to main shaft; When the distance between the two male part end faces increased, disengaging pawl pulling motion bar made the driving wheel base overcome spring force and follower is separated, and follower then stops operating, and realizes separating.Its deficiency is: 1,, make that when running up, it is bigger that release bearing bears pressure owing to adopt fricting transmissioning mode, and serious wear, fragile; 2, it is big that its complex structure, friction plate are regulated difficulty, needs after the wearing and tearing to change, and difficulty is adjusted in the gap, easily causes the friction plate scaling loss of skidding; Internal gas flow during 3, because of vibrations, running, influences such as dust easily cause clutch separation unclear, easily cause security incident.

The model utility content

The purpose of this utility model provides a kind of coupling type clutch, makes it can overcome above-mentioned defective, and it is simple in structure, reliable operation, convenient separation.

The purpose of this utility model is achieved in that the coupling type clutch, the colyliform clutch main body that comprises hollow, clutch main body outer round surface is provided with belt grooves, clutch main body both sides are provided with the cavity in the end cap closed clutch main body, the clutch main body axis is provided with a main shaft that is installed in the bearing support, two end cap is provided with bearing, described bearing housing is contained on the main shaft, be set with axle sleeve on the main shaft between the two bearings, also be provided with in the clutch main body and be sleeved on the outer driving wheel base of axle sleeve, the driving wheel backrest of driving wheel base periphery and the setting of clutch main body inner circumference is coupled, circumferentially be evenly equipped with at least two supporting bases near on the end cap of bearing support one side, each supporting base and disengaging pawl middle part are hinged, each disengaging pawl one end is conflicted in a side that is set in the release bearing on the main shaft, between release bearing and bearing support, be set with the male part that two working surfaces are obliquely installed and match on the main shaft, one of them male part side is connected with pull bar through connecting rod, each disengaging pawl the other end is respectively equipped with the motion bar that vertically passes end cap, motion bar is connected with the driving wheel base, be provided with spring between driving wheel base and the close end cap of bearing support one side, described axle sleeve is provided with the follower base outward, be provided with follower and driving wheel in opposite directions between follower base and the driving wheel base, follower is arranged on the follower base, driving wheel is arranged on the driving wheel base, and the surface in opposite directions of follower and driving wheel is provided with adaptive mutually projection and depression.

During the utility model work, the pulling pull bar drives one of male part and rotates an angle, and the distance between the end face of two male parts increases or reduces, when distance reduces, release bearing promotes the disengaging pawl action, acting force of the spring promotes the driving wheel base, makes driving wheel touch follower, hangs mutually with depression when projection and runs into a time-out, the clutch main body can drive main shaft and rotate, under the spring force effect, projection and depression can further be fastened togather, and transmission can be carried out more smoothly; When the distance between the two male part end faces increased, disengaging pawl pulling motion bar was separated driving wheel and follower, and the clutch main body can be rotated further, and follower then stops operating, and realizes clutch separation.The utility model is simple in structure, reliable operation, convenient separation, and compared with prior art, its separation and in conjunction with not influenced by dust during work, can not skidded; Its gap is easy to adjust; The suffered thrust of release bearing is little, and is not easy to wear, uses more reliable; The transmission joint that the utility model can be used as tractor and its peripheral unit uses.

Described spring can be sleeved on the motion bar, also can be sleeved on outside the axle sleeve, can also be on motion bar and axle sleeve equal pocketed springs.
