Abstract
The utility model relates to an operating platform bearing of a double-column vertical lathe, in particular to a novel thrust ball bearing. The novel thrust ball bearing comprises two washers, a plurality of steel balls and a plurality of retainers, wherein the number of the steel balls is multiple times that of the retainers. Connecting bolt holes are arranged in the washers to ensure that the bearing is connected with an operating platform and a base of the vertical lathe, thus saving the space; and the steel balls roll on the raceways of the two washers, a plurality of pocket holes are arranged in the retainers, the steel balls are embedded in the pocket holes of the retainers, the steel balls are separated by the retainers, the directions of the two adjacent pocket holes for the retainers are opposite, so that the bearing operates more steadily, and the noise is reduced.
Description
Technical field
The utility model relates to a kind of twin columns vertical lathe worktable load-bearing bearing-novel thrust ball bearing.
Background technique
Bearing is the crucial mechanical basic part of the national economic development, is widely used in national economy every field such as Aero-Space, railway, automobile, tractor, lathe, motor, boats and ships, oil-well rig, mine, metallurgy, milling train, chemical industry, press for extracting juice sugar, papermaking, printing, textile machinery.
The load-bearing bearing of the worktable of twin columns vertical lathe is a thrust ball bearing, because this bearing boundary dimension is big, and the integral cage processing difficulties, so bearing is in the past separated this kind structure galloping with several spacing blocks between the steel ball, noise is big, solves this difficult problem so press for.
The model utility content
The purpose of this utility model: in order to satisfy low noise, the requirement stably of turning round, the utility model provides a kind of novel thrust ball bearing.
The technical solution of the utility model is: a kind of novel thrust ball bearing, comprise two packing rings 1, plurality of steel balls 2 and several retainers 3, and the number of steel ball 2 is multiples of retainer 3 numbers.Have the connecting bolt hole on the packing ring 1, make bearing link to each other conserve space with base with the worktable of vertical lathe; Steel ball 2 rolls on the raceway of two packing rings 1, has some pockets hole on the retainer 3, and steel ball 2 is embedded in the pocket hole of retainer 3, separates with retainer 3 between the steel ball 2, and retainer 3 adjacent two pocket hole directions are opposite, make bearing operation more steady, reduce noise.
The beneficial effects of the utility model are: the utility model noise is low, and running steadily meets client's usage requirement, has boundless market prospects.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. packing ring, 2. steel ball, 3. retainer.
Fig. 2 is the utility model retainer structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, a kind of novel thrust ball bearing, model is HTB2197, comprise 1,120 steel balls 2 of two packing rings and 20 retainers 3 compositions, the diameter of steel ball 2 is 45mm, has the connecting bolt hole on the packing ring 1, make bearing link to each other conserve space with base with the worktable of vertical lathe; Steel ball 2 rolls on the raceway of two packing rings 1, have 6 pocket holes on each retainer 3, steel ball 2 is embedded in the pocket hole of retainer 3, separate with retainer 3 between the steel ball 2, as shown in Figure 2, retainer 3 adjacent two pocket hole directions are opposite, see A-A and B-B sectional view among Fig. 2, make bearing operation more steady, reduce noise.
