Description
Technical field
Patent of the present invention relates to a kind of cardan wheel, particularly a kind of heavy-load mini elastic universal wheel.
Background technology
The existing small-sized cardan wheel that is commercially available generally is applicable to light-duty little impact load, and is simple in structure, but only possesses the effect that simple support turns to, support roller does not have elasticity with respect to fixed mount, therefore, the ability of the load that withstands shocks is less, to the adaptive capacity of uneven ground a little less than.And the rubber-like cardan wheel, volume is big, and complex structure generally is applicable to the big machinery equipment.
Summary of the invention
The objective of the invention is to be the defective that exists at prior art provides a kind of heavy-load mini elastic universal wheel, and structure is simpler, and volume is less, but has heavily loaded elastic performance.
For achieving the above object, the present invention adopts following technical proposals:
A kind of heavy-load mini elastic universal wheel comprises mount pad, body and roller, it is characterized in that described mount pad is rotatably connected on the upper end of described body by a pivot shaft and bearing; Both sides, the bottom diaphragm plate of described body is hinged with the middle part of two parallel connecting panels respectively mutually by two minor axises; Pass through the described roller of bearing pin rotational support between described two connecting panel one ends; And the other end of two connecting panels links to each other by a major axis, and passes through two spring conductor rods and two die springs resilient mountings respectively in the middle part of described body.
The installation screw is arranged on the above-mentioned mount pad, be used for mount pad and be connected by screw with link; Described mount pad is captiveed joint with the upper end flange of described pivot shaft by screw; Described bearing is that head bearing and the stacked formation of lower bearing are placed in the described body upper opening chamber, captives joint with described body by screw by a bearing cap shim, and the outer ring of fixing upper and lower bearing; Described pivot shaft passes described bearing cap shim, and be supported on the inner ring of head bearing by the convex shoulder at pivot shaft middle part, pivot shaft and metal (upper inner ring flush fit, the bottom has external thread rotary to join jam nut, and the inner ring assembly of metal (upper tightly and with pivot shaft is captiveed joint.
The present invention compared with prior art, have following existing and outstanding substantive distinguishing features and the remarkable advantage easily seen: mount pad of the present invention is by pivot shaft and the bearing body that is rotationally connected, roller constitutes resilient mounting in the bottom of body by connecting panel and die springs, reasonable in design, be skillfully constructed, simple and compact for structure, volume is little and have heavily loaded elastic performance.
Description of drawings:
Fig. 1 is the structural representation (being A-A place cutaway view among Fig. 2) of one embodiment of the invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the axle side scheme drawing of Fig. 1.
The specific embodiment:
A preferred embodiment of the present invention accompanying drawings is as follows: comprise mount pad 2, body 6 and roller 8 referring to this heavy-load mini elastic universal wheel of Fig. 1, it is characterized in that described mount pad 2 is rotatably connected on the upper end of described body 6 by a pivot shaft 1 and bearing 4,5; Both sides, the bottom diaphragm plate of described body 6 is hinged with the middle part of two parallel connecting panels 10 respectively mutually by two minor axises 9; Pass through the described roller 8 of bearing pin rotational support between described two connecting panel 10 1 ends; And the other end of two connecting panels 10 links to each other by a major axis 11, and passes through two spring conductor rods 14 and two die springs 12 resilient mountings respectively in the middle part of described body 6.
On the above-mentioned mount pad 2 the installation screw is arranged, be used for mount pad 2 and be connected by screw with link; Described mount pad 2 is captiveed joint with the upper end flange of described pivot shaft 1 by screw; Described bearing 4,5 is placed in the described body 6 upper opening chambers for head bearing 4 and lower bearing 5 stacked formations, captives joint with described body 6 by screw by a bearing cap shim 3, and the outer ring of fixing upper and lower bearing 4,5; Described pivot shaft 1 passes described bearing cap shim 3, and be supported on the inner ring of head bearing 4 by the convex shoulder at pivot shaft 1 middle part, pivot shaft 1 and metal (upper 4,5 inner ring flush fits, the bottom has external thread rotary to join jam nut, and the inner ring assembly of metal (upper 4,5 tightly and with pivot shaft 1 is captiveed joint.
Referring to Fig. 1, Fig. 2 and Fig. 3, above-mentioned rollers 8 is supported on connecting panel 10 by bearing pin, in the roller 8 bearing is installed, can freely rotate around self axis, promptly roller 8 relatively connecting panel 10 freely roll.Minor axis 9 is supported on the connecting panel 10 by interference fit.Major axis 11 is supported on the connecting panel 10 by interference fit.One end of die springs 12 is supported on the plane of body 6, and the other end cooperates with the end face of adjustment nut 13.Spring conductor rod 14 passes die springs 12 intermediate throughholes, and an end is provided with screw thread and adjustment nut 13 screws, and an end is provided with through hole and major axis 11 transition fit.
Motion flow: mount pad 2 is installed in the lower surface of carrying motion platform by bolt, and roller 8 contacts with ground, because roller 8 can be around himself axis free rotation, so roller 8 will advance in ground surface.Be loaded into the Item Weight of carrying on the motion platform by platform action on mount pad 2, transmission by head bearing 4 and lower bearing 5 is passed to body 6 with power, by the lever system of being made up of roller 8, minor axis 9, connecting panel 10, major axis 11, die springs 12, adjustment nut 13, spring conductor rod 14 power is passed to roller 8.Because pivot shaft 1 is provided with the lower bearing (being generally tapered roller bearing or angular contact ball bearing) that can bear axial load, so can realize the transmission of axial force between each part; Because pivot shaft 1 is provided with the head bearing (being generally deep groove ball bearing or angular contact ball bearing) that can bear radial weight, so can realize the transmission of diametral load between each part; When the carrying motion platform turned to, under the support of bearing, body 6 kept under the situation of former constant bearing, and pivot shaft 1 and mount pad 2 rotate corresponding angle around the axis of pivot shaft 1, to satisfy the demand that the carrying motion platform turns to.
Because the right-hand member of connecting panel 10 is provided with die springs 12, can adapt to the distortion that occurs in connecting panel 10 left ends by its elastic deformation, thereby it is ground concavo-convex to make that roller 8 adapts to.And by regulating the screwing length of adjustment nut 13 on spring conductor rod 14, can adjust the predetermincd tension that die springs 12 acts on spring conductor rod 14, thereby adjust the deflection of connecting panel 10 right-hand members that cause because of the variation that acts on the power on the roller 8.
