Abstract
The utility model relates to a machine part field especially relates to a novel grab bucket axis, axostylus axostyle, the shaft shoulder, the axle head baffle of cylinder form are all become including integrated into one piece, the cover is equipped with the axle sleeve on the axostylus axostyle between the shaft shoulder and the bearing baffle, installs an antifriction bearing between axle sleeve and axle head baffle, installs the 2nd antifriction bearing at the axle sleeve near the one end of the shaft shoulder, the one end that the 2nd antifriction bearing is close to the shaft shoulder is provided with the mounting. The utility model discloses a two rolls parallel bearing design, have improved stability, have reduced frictional force, simple structure, reasonable in design.
Description
Technical field
The utility model relates to mechanical parts field, particularly relates to a kind of novel grab bucket axis.
Background technique
Axle is through the cylindrical object in the middle of bearing or in the middle of wheel or in the middle of gear, but also have small part to be square.Axle is the mechanical parts that support rotary part turning round therewith transmits motion, moment of torsion or moment of flexure.Be generally round metal shaft-like, each section can have different diameters.The part doing rotation motion in machine is just contained on axle.
At present, what the axis in the grab mechanisms in traditional crane gear adopted is single rolling bearing, and such design safety factor is low, and built on the sand, friction factor is high for structure.
Summary of the invention
In order to solve the problem, the utility model provides a kind of novel grab bucket axis, and its stability is high, and friction factor is little.
In order to solve the problems of the technologies described above, technical solutions of the utility model are: comprise the one-body molded axostylus axostyle, the shaft shoulder, the axle end baffle plate that all become cylindrical shape, shaft rod upper sleeve between the described shaft shoulder and bearing baffle is provided with axle sleeve, first rolling bearing is installed between axle sleeve and axle end baffle plate, be provided with the second rolling bearing at axle sleeve near one end of the shaft shoulder, described second rolling bearing is provided with fixed block near one end of the shaft shoulder.
Preferably, described first rolling bearing is provided with first ring connected in star in the one end near the shaft shoulder.
Preferably, described second rolling bearing is provided with the second annular groove in the one end near the shaft shoulder.
The beneficial effects of the utility model are: adopt two design bearing arranged side by side of rolling, improve stability, reduce frictional force, structure is simple, reasonable in design.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model embodiment.
Accompanying drawing acceptance of the bid note is described below: 1. axostylus axostyle, the 2. shaft shoulder, 3. axle end baffle plate, 4. axle sleeve, 5. the first rolling bearing, 51 first ring connected in stars, 6. the second rolling bearing, 61. second annular groove, 7. fixed blocks.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described, but the utility model is not limited to these embodiments.
By reference to the accompanying drawings 1, a kind of novel grab bucket axis, comprise the one-body molded axostylus axostyle 1, the shaft shoulder 2, the axle end baffle plate 3 that all become cylindrical shape, axostylus axostyle 1 between the described shaft shoulder 2 and bearing baffle 3 is arranged with axle sleeve 4, first rolling bearing 5 is installed between axle sleeve 4 and axle end baffle plate 3, be provided with the second rolling bearing 6 at axle sleeve 4 near one end of the shaft shoulder 2, described second rolling bearing 6 is provided with fixed block 7 near one end of the shaft shoulder 2.Described first rolling bearing 5 is provided with first ring connected in star 51 in the one end near the shaft shoulder 2.Described second rolling bearing 6 is provided with the second annular groove 61 in the one end near the shaft shoulder 2.
By technique scheme, adopt two design bearing arranged side by side of rolling, improve stability, reduce frictional force, structure is simple, reasonable in design.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
