Meanwhile, the service life of the bearing is shortened, and the normal use of the turner is influenced.
The original bearing of the turner is high in cost, and during replacement, goods need to be prepared in advance in a warehouse, so that the turner occupies stock, influences use and is high in maintenance cost.
Disclosure of Invention
The utility model discloses a solve the problem that the foreign matter effect of preventing of the bearing of turning over the throwing machine among the prior art is poor, life weak point and maintenance cost are high, but provide a but prevent foreign matter self-aligning bearing.
In order to realize the purpose, the technical scheme of the utility model is that:
a foreign matter preventing self-aligning bearing comprises a bearing seat, wherein a first shaft sleeve is arranged inside the bearing seat, and a bearing is arranged between the first shaft sleeve and the bearing seat; the bearing is matched with the first shaft sleeve; two skeleton seals are respectively arranged on two sides of the bearing, and the two skeleton seals are arranged back to back; and a second shaft sleeve is fixed at the end part of the first shaft sleeve, which extends out of the bearing seat.
Furthermore, a clamp spring is arranged between the bearing and the framework seal and clamped into the bearing seat.
Furthermore, a hole is formed in one side portion of the shaft sleeve, and a pin is arranged on the second shaft sleeve and is arranged in the hole.
Furthermore, the framework seal of the bearing seat far away from the second shaft sleeve is connected through screws.
Through the technical scheme, the beneficial effects of the utility model are that:
the bearing of the utility model is a self-aligning roller bearing, which can automatically align and normally work under the condition that the relative inclination of the inner and outer peripheries of the turner shaft is not big; the bearing is fixed on the first shaft sleeve through the clamp spring, and the clamp spring is clamped in the bearing seat, so that the bearing, the first shaft sleeve and the bearing seat are fixedly connected, and the situation that the positions of the bearing, the first shaft sleeve and the bearing seat are deviated in the using process to influence the use is prevented; the framework seals at the two sides of the bearing are respectively installed back to back, so that foreign matters can be effectively prevented from entering the bearing, the normal work of the shaft is prevented from being influenced, the shortened shaft is prevented from shortening the service life of the shaft, and the service life of the bearing is prolonged; the utility model discloses simple structure, it is with low costs, the replaceability is strong, easy maintenance.
