Abstract
The utility model discloses an universal wheel, which comprises a wheel, a wheel shaft, a wheel rack, a bearing and a bearing seat, wherein the wheel is connected on the lower end of the wheel frame by the wheel shaft, the upper end of the wheel frame and the bearing are arranged in the bearing seat together, and a lower port of the bearing seat is provided with a sealing device. The sealing device is a skeleton oil seal, and a skeleton oil seal insulation bearing contacts with external environment, thereby preventing dust from entering the bearing. Furthermore, the universal wheel also prevents lubricating agent in the bearing from dripping through arranging the skeleton oil seal, simultaneously guarantees lubrication of the bearing constantly, and is not easy to damage the bearing. The universal wheel belongs to the technical field of universal wheels.
Description
Technical field
The utility model relates to a kind of cardan wheel.
Background technology
Cardan wheel is mounted in a kind of annex of being convenient to move on object bottom or the leg.The cardan wheel that generally uses mainly comprises following parts in the market, as shown in Figure 1: wheel 1, wheel shaft 2, wheel carrier 3, bearing (4,5), bearing seat 6, wherein, wheel shaft 2 is connected the lower end of wheel carrier 3 with wheel, and the upper end of wheel carrier 3 and clutch shaft bearing 4, second bearing 5 are positioned at bearing seat 6 together.This cardan wheel has the following disadvantages: second bearing, 5 lower surface long term exposure are in air, koniology enters in the bearing easily, damage bearing, in addition, the wheel lubrication prescription in the bearing is very easily dry, also following easily of wheel lubrication prescription, time one is of a specified duration, the drying that bearing becomes, and it is influenced to cause bearing to rotate, bearing damages easily, has shortened the normal practical life of bearing.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of and can effectively protect the bearing on the cardan wheel not to be subjected to the lubricated constantly and long cardan wheel of bearing practical life of extraneous effect of dust, bearing.
The technical scheme of taking of the present utility model is: cardan wheel, comprise wheel, wheel shaft, wheel carrier, bearing and bearing seat, wherein, wheel shaft is connected wheel the lower end of wheel carrier, the upper end of wheel carrier and bearing are positioned at bearing seat together, and described bearing seat lower port place is equipped with sealing arrangement.Described sealing arrangement is an outside framework oil seal.
Described outside framework oil seal is positioned at bearing seat.
As improvement, described bearing seat lateral surface is provided with connecting device, and described connecting device is a screw, makes things convenient for cardan wheel to be installed on other objects.
The beneficial effects of the utility model are: the bearing seat lower port of the utility model cardan wheel lower end is installed sealing arrangement, described sealing arrangement is an outside framework oil seal, described outside framework oil seal contacts with external environment at isolated bearing, has stopped that dust enters in the bearing; In addition, outside framework oil seal has been installed has also been avoided following of bearing internal lubricant, guaranteed that simultaneously the moment of bearing is lubricated.
