Background technique
Bearing is applied to be mainly used in suspension type center transmission shaft is carried out radial location under water in width of cloth stream pond suspension type center transmission thickner or the stirrer under water.
As shown in Figure 1: be the structure of bearing under water commonly used at present.Described bearing under water comprises center transmission shaft 1, and hang under the output shaft of drive unit on transmission shaft 1 top, described center, and drives to be installed in and scrape arm assembly or blade rotation on the center transmission shaft 1.The lower end of center transmission shaft 1 is provided with centration axis 2 and footstock 3, and an end and the center transmission shaft 1 of described centration axis 2 fix, and the other end is embedded in the footstock 3; Center transmission shaft 1 all can rotate relative to footstock 3 with centration axis 2.The top of described footstock 3 is provided with positioning hole 6, centration axis 2 is embedded in the footstock 3 after passing positioning hole 6 corresponding to the other end that links to each other with center transmission shaft 1, carry out radial location by 6 pairs of centration axis of positioning hole 2, footstock 3 is fixed on the backing plate 4, after adjusting to the right place, backing plate 4 and pre-embedded steel slab field welding at the bottom of the pond.
Its shortcoming of said structure is: (generally be not less than 3 meters) when transmission shaft 1 length in center is very big, because its straightness accuracy is difficult to guarantee, therefore transmission shaft 1 top and bottom in center produce eccentric when rotating, in such cases, 6 pairs of centration axis 2 of positioning hole on the footstock 3 will produce very big rotational resistance, and can produce uneven wear to positioning hole on the footstock 36 and centration axis 2, and can shorten the working life of bearing under water, influence is normally used.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of improved bearing under water is provided, and it is simple in structure, uses easy to operately, increases the service life, and reduces user cost.
According to the technological scheme that the utility model provides, described improved bearing under water comprises center transmission shaft and centration axis; Be provided with universal joint between described center transmission shaft and centration axis; Described centration axis is provided with footstock corresponding to the other end that links to each other with universal joint, and footstock is provided with positioning hole, and centration axis is embedded in the footstock after passing positioning hole corresponding to the other end that links to each other with universal joint; Described centration axis can be rotated relative to footstock.
Described footstock lower end is provided with backing plate, and footstock and backing plate utilize clamping bolt to fix.Described centration axis is provided with the shaft shoulder corresponding to the end that is embedded in the footstock.The two ends of described universal joint utilize bearing pin and center transmission shaft, centration axis to be fixedly connected respectively.Described bearing pin is provided with position limit pin.
Advantage of the present utility model: by between center transmission shaft and centration axis, universal joint being set, universal joint fixes by bearing pin and center transmission shaft, centration axis, when the straightness accuracy of center transmission shaft exists than mistake, universal joint can satisfy the beat of certain amplitude, thereby the axis that makes the positioning hole on centration axis and the footstock is all the time on same straight line, prevented the center transmission shaft resistance that rotates, avoided producing uneven wear between the positioning hole on centration axis and the footstock, prolonged the working life of bearing under water; Simple in structure, use easy to operately, reduce user cost.

Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As Fig. 2～shown in Figure 3: the utility model comprises center transmission shaft 1, centration axis 2, footstock 3, backing plate 4, universal joint 5, positioning hole 6, clamping bolt 7, the shaft shoulder 8, bearing pin 9 and position limit pin 10.
As shown in Figures 2 and 3: 2 of described center transmission shaft 1 and centration axis are provided with universal joint 5, and the two ends of described universal joint 5 utilize bearing pin 9 and center transmission shaft 1 and centration axis 2 to fix respectively, and the end of bearing pin 9 is provided with position limit pin 10, can carry out spacing to bearing pin 9.Centration axis 2 is provided with footstock 3 corresponding to the other end that links to each other with universal joint 5, and footstock 3 is provided with positioning hole 6 with centration axis 2 corresponding surfaces.Centration axis 2 is embedded in the footstock 3 after passing positioning hole 6 corresponding to the other end that links to each other with universal joint 5; Centration axis 2 can be rotated relative to footstock 3; Positioning hole 6 can carry out radial location to centration axis 2.Centration axis 2 is provided with the shaft shoulder 8 corresponding to the end that is embedded in the footstock 3; Centration axis 2 can avoid centration axis 2 in rotation process by the effect of the shaft shoulder 8, deviates from from positioning hole 6.
The lower end of described footstock 3 is provided with backing plate 4, and footstock 3 utilizes clamping bolt 7 and backing plate 4 to be fastened and connected.Backing plate 4 welds fixing with pre-embedded steel slab at the bottom of the pond mutually.
