Abstract
The utility model relates to a kind of holder for three-row cylindrical roller combination turntable bearings, propose a kind of holder for three-row cylindrical roller combination turntable bearing with seat ring.A kind of holder for three-row cylindrical roller combination turntable bearing with seat ring proposed has mutually matched lasso I and lasso II；Lasso I is coupled by two half lassos setting up and down；Lasso II has carrier ring；There are three raceways to install three row's cylindrical rollers on carrier ring；The lower end surface of carrier ring has downwardly projecting protrusion；Lasso II also has the seat ring being arranged in below carrier ring；The lower end surface of the seat ring has the groove matched with the protrusion kiss of carrier ring lower end surface；The seat ring and the carrier ring convex-concave fastening are integrated, mutually carry out radial positioning, and are connected by bolts and are integrated.The utility model solves the problems, such as that the forge weight of whole lasso has exceeded forging production equipment working ability；Seat ring can select the lower material of performance to be substituted, to reduce material cost.
Description
Technical field
The utility model relates to a kind of holder for three-row cylindrical roller combination turntable bearings, and in particular to a kind of three rows circle with seat ring
Column roller combines turntable bearing.
Background technique
Holder for three-row cylindrical roller combination turntable bearing is usually made of lasso, rolling element, retainer, sealing ring etc..Lasso point
For outer ring and inner ring.It is needed for installation, must have one in outer ring and inner ring for two halves composite structure, two halves lasso passes through spiral shell
Bolt connection is integral.When producing turntable bearing, the forging of manufacture lasso is first had to, for holder for three-row cylindrical roller combination turntable axis
It holds, needs to manufacture three lasso forging, i.e., the whole forging of lasso and the forging of two and half lassos.It is whole in three lasso forging
The forging of body lasso is most heavy.For some large-sized bearings, it may appear that the forge weight of monoblock type lasso is overweight, has exceeded forging
The working ability of part production equipment.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to propose a kind of three-row cylinder roller combination with seat ring
Turntable bearing.
The utility model is to complete above-mentioned purpose to adopt the following technical scheme that
A kind of holder for three-row cylindrical roller combination turntable bearing with seat ring, the combination dials bearing have mutually matched
Lasso I and lasso II；The lasso I is coupled by two half lassos setting up and down；The lasso II has carrying
Circle；There are three raceways to install three row's cylindrical rollers on the carrier ring；The lower end surface of the carrier ring have to
The protrusion of lower protrusion；The lasso II also has the seat ring being arranged in below carrier ring；The lower end surface of the seat ring have with
The groove that the protrusion kiss of carrier ring lower end surface is matched；The seat ring and the carrier ring convex-concave fastening are integrated, mutually
Radial positioning is carried out, and is connected by bolts and is integrated.
The lasso I is outer ring, and the lasso II is inner ring.
The lasso I is inner ring, and the lasso II is outer ring.
The utility model proposes a kind of holder for three-row cylindrical roller combination turntable bearing with seat ring, lasso II is using by carrying
Circle and seat ring couple it is integral after it is identical as the former whole function of lasso, since former entirety lasso is divided into two parts, solution
The problem of forge weight of whole lasso has exceeded forging production equipment working ability；Due to there is no raceway, function on seat ring
Can be similar with host mounting seat, without acting on as there is the bearing ring of raceway to bear complex stress, therefore performance can be selected
Lower material replaces original material, to reduce material cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, lasso I, 2, carrier ring, 3, seat ring, 4, bolt.
Specific embodiment
The utility model is illustrated with reference to the drawings and specific embodiments:
As shown in Figure 1, a kind of holder for three-row cylindrical roller combination turntable bearing with seat ring, the combination dials bearing have
Mutually matched lasso I and lasso II；The lasso I is coupled by two half lassos setting up and down；The lasso
II has carrier ring 2；There are three raceways to install three row's cylindrical rollers on the carrier ring 2；The carrier ring 2
Lower end surface has downwardly projecting protrusion；The lasso II also has the seat ring 3 being arranged in below carrier ring；The seat ring 3
Lower end surface there is the groove matched of protrusion kiss with carrier ring lower end surface；The seat ring 3 and 2 convex-concave of carrier ring
Fastening is integrated, mutually carries out radial positioning, and is connected as one by bolt 4.
The lasso I is outer ring, and the lasso II is inner ring.
The lasso I is inner ring, and the lasso II is outer ring.
