Abstract
Aiming at the defects that a bearing with a traditional structure can not satisfy the requirements of high-precision, low friction and low noise of a machine tool, the utility model provides a novel machine tool main shaft bearing adopting a nylon holding rack; the main shaft bearing comprises an outer ring, an inner ring, a roller and the holding rack; a direct locking pocket and a straight claw are arranged on the holding rack; and the roller is filled in the pocket after the straight claw is deformed elastically, so that the roller and the holding rack are integrated as a whole. The novel nylon holding rack adopts the direct locking pocket, so that the mold technology is simplified, the cost is lowered, a rolling body can be enabled to operate freely, reposefully and flexibly in the pocket of the holding rack, and the vibration noise of a host machine is lowered; and the bearing has the advantages of good wear resisting property, low friction coefficient and good self-lubricating performance.
Description
Technical field
The utility model belongs to technical field of bearings, relates to a kind of novel machine tool mainshaft bearing with nylon cages.
Background technique
At present, along with the fast development of high speed, high precision machine tool, more and more higher to the required precision of its main shaft, noise is more and more lower, and the old airframe bearing that supports accurate main shaft has been difficult to satisfy the requirement of the highi degree of accuracy of lathe, low friction, low noise.The former employing of Biserial cylindrical roller bearing that machine tool chief axis is supporting be the brass retainer, weight is big, easy copper foam dropping, therefore, noise is big during the main shaft high speed rotating, and temperature rise.
Summary of the invention
At above deficiency, the purpose of this utility model provides a kind of novel machine tool mainshaft bearing with nylon cages, to satisfy the demand of low friction, low noise.
The technical solution of the utility model is: a kind of novel machine tool mainshaft bearing with nylon cages, form by outer ring, inner ring, roller and retainer, retainer 4 is provided with straight lock pocket hole 5 and straight pawl 6, roller 3 produces in the pocket hole 5 of packing into after the resiliently deformables by straight pawl 6, and roller 3 and retainer 4 are become one.
The beneficial effects of the utility model are: this novel nylon retainer adopts straight lock pocket hole, simplified mould process, reduced cost, can guarantee that rolling element goes slick, steadily, flexibly in retainer pocket hole, and reduced the main frame vibrating noise, the bearing wear-resisting property is good, and friction factor is low, and self-lubricating property is good.Thereby realize the low friction of product, low noise requirement.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the utility model is elaborated:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a retainer structural representation of the present utility model.
Among the figure, 1, the outer ring, 2, inner ring, 3, roller, 4, retainer, 5, directly lock the pocket hole, 6, straight pawl
Embodiment
As shown in Figure 1, the utility model is made up of outer ring, inner ring, roller and retainer, and retainer 4 is provided with straight lock pocket hole 5 and straight pawl 6, and roller 3 is packed in the straight lock pocket hole 5 after producing resiliently deformable by straight pawl 6, and roller 3 and retainer 4 are become one.
