Abstract
The utility model discloses a rolling bearing of a tube mill. The rolling bearing comprises a hollow shaft arranged on a tube mill cylinder, and a rolling bearing body is arranged on the hollow shaft which is supported on a bearing seat through the rolling bearing. An upper bearing cover covers the rolling bearing, a spherical bearing seat ring is mounted between the rolling bearing and the bearing seat, one side of the rolling bearing is abutted against a step of the hollow shaft, the other side of the rolling bearing is fittingly fastened with a groove on the hollow shaft through a retainer ring, the upper bearing cover, the bearing seat and sealing spaces on two sides of the rolling bearing form a sealed bearing chamber, so that entering dust can be reduced. The rolling bearing substituting for a sliding bearing can reduce friction coefficient and rotation resistance of the tube mill cylinder and save motor power.
Description
Technical field
The utility model relates to a kind of rolling bearing of tuber grinder.
Background technique
For a long time, the supporting way of middle-size and small-size tuber grinder all is the quill shaft of being held tuber grinder by the spherical bush of surface casting bus alloy basically, realize the rotation of cylindrical shell by the slip of tube grinder hollow shaft on spherical bush, this sliding bearing mode, because area of contact is large, bearing capacity is large, therefore for many years consistent use so far.But the shortcoming of sliding bearing is: surface friction drag is large, the power consumption of grinding machine is high, to lubricated require high, easily the tile kilning phenomenon appears, regular maintenance requires high.
Summary of the invention
In order to overcome defects, the utility model provides the rolling bearing of the tuber grinder that a kind of energy consumption is low, lubricating requirement is low, regular maintenance is few and economic benefit is high.
The utility model for the technological scheme that solves its technical problem and adopt is: a kind of rolling bearing of tuber grinder, comprise the quill shaft that is arranged on the barrel body of tube mill, be provided with rolling bearing on the described quill shaft, described quill shaft by roller bearings on bearing support, be covered with bearing upper cover on the described rolling bearing, the spherical bearing seat ring is installed between described rolling bearing and bearing support, one side of described rolling bearing leans against on the step of quill shaft, opposite side cooperates chucking by back-up ring with groove on the quill shaft, described bearing upper cover, the seal space of bearing support and rolling bearing both sides forms the bearing chamber of a sealing, can reduce entering of dust.
As further improvement of the utility model, described spherical bearing seat ring is the bearing race of outer spherical surface, adopts the bearing race of outer spherical surface to solve the vibration problems that the tuber grinder two ends may exist, and guarantees that bearing can have a certain amount of swing.
The beneficial effects of the utility model are: replace sliding bearing with rolling bearing, the change sliding bearing is rolling bearing, and the coefficient of can reducing friction reduces the resistance that grinding mill barrel rotates, and saves power of motor; Tuber grinder uses rolling bearing not only to save energy consumption, and is satisfying under the prerequisite of lubricating requirement, and basic Maintenance free can bring considerable economic benefit to the user, should be the developing direction of tuber grinder bearing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1, quill shaft, 2, bearing upper cover, 3, rolling bearing, 4, the spherical bearing seat ring, 5, bearing support, 6, back-up ring, 7, bearing chamber.
Embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
As shown in Figure 1, a kind of rolling bearing of tuber grinder, comprise the quill shaft 1 that is arranged on the barrel body of tube mill, be provided with rolling bearing 3 on the described quill shaft 1, described quill shaft 1 is supported on the bearing support 5 by rolling bearing 3, be covered with bearing upper cover 2 on the described rolling bearing 3, between described rolling bearing 3 and bearing support 5, spherical bearing seat ring 4 is installed, described spherical bearing seat ring 4 is the bearing race of outer spherical surface, adopt the bearing race of outer spherical surface to solve the vibration problems that the tuber grinder two ends may exist, guarantee that bearing can have a certain amount of swing, one side of described rolling bearing 3 leans against on the step of quill shaft 1, opposite side cooperates chucking, described bearing upper cover 2 by back-up ring 6 with groove on the quill shaft 1, the seal space of bearing support 5 and rolling bearing 3 both sides forms the bearing chamber 7 of a sealing, can reduce entering of dust.
The utility model replaces sliding bearing with rolling bearing, and the change sliding bearing is rolling bearing, has reduced friction factor, has reduced the resistance that grinding mill barrel rotates, and has saved power of motor; Tuber grinder uses rolling bearing not only to save energy consumption simultaneously, and satisfying under the prerequisite of lubricating requirement, basic Maintenance free, can bring considerable economic benefit to the user, should be the developing direction of tuber grinder bearing, through the use condition of past hundred all size tuber grinders in the past few years, energy-saving effect be very obvious, can realize economizing on electricity more than 10%, obtain user's extensive approval.
