Abstract

A kind of Biserial cylindrical roller bearing for being adapted for mount on conical surface axle, including outer ring and inner ring.Two integrated cages are set up in parallel between outer ring and inner ring, multiple cylindrical rollers, outer ring raceway band taper are installed on each integrated cage, and taper direction is consistent with inner ring internal diameter taper direction.It is to use integrated cage, the locking point of external diameter, outer ring raceway band taper with traditional biserial cylinder difference, and taper direction is consistent with inner ring internal diameter taper direction.It is simple in construction, easy disassembly, improve load and the life-span of bearing.In the case where axle is the conical surface, outer raceway band taper can compensate for inner ring deformation it is inconsistent caused by bearing or so end clearance it is poor, extend the life-span of bearing.

Description

A kind of Biserial cylindrical roller bearing for being adapted for mount on conical surface axle

Technical field：

Technical field of bearings is the utility model is related to, is rolled more particularly to a kind of biserial cylinder for being adapted for mount on conical surface axle Sub- bearing.

Background technology：

Common Biserial cylindrical roller bearing uses traditional rivet arrangement retainer, because structure limits, roller length And grain number is all restricted, so load can not be improved further.The inside and outside raceway of bearing is all to use the face of cylinder, and bearing is left Radial clearance must be consistent before the installation of right side position.When bearing bore diameter is the conical surface, when on conical surface axle, due to the conical surface The inconsistent of inner ring arranged on left and right sides end face wall thickness is caused, and in the case that the magnitude of interference is the same, it will result in inner ring left and right two The deflection of side end face is inconsistent, inconsistent so as to result in the left and right endface position radial clearance after bearing installation.And radially Gap it is inconsistent, cylindrical roller can be caused to be contacted with the point of outer raceway, be very easy to the damage for causing bearing.And then delay Manufacturing schedule, add production cost.When bearing bore diameter is the conical surface, traditional Biserial cylindrical roller bearing has been difficult to meet The demand of client, improvement need to be optimized to traditional bearing structure.

Utility model content

The purpose of this utility model is to provide a kind of Biserial cylindrical roller bearing for being adapted for mount on conical surface axle, is adapted to fit On conical surface axle, there are larger rated load, and the consistent biserial cylinder rolling of bearing or so endface position end-play after installation Sub- bearing, as shown in Figure 5 a1=b1.

The technical scheme of use is：

A kind of Biserial cylindrical roller bearing for being adapted for mount on conical surface axle, including outer ring and inner ring.

Technical points are：

Two integrated cages are set up in parallel between outer ring and inner ring, multiple cylinder rollings are installed on each integrated cage Son, outer ring raceway band taper, and taper direction is consistent with inner ring internal diameter taper direction.

It is to use integrated cage, the locking point of external diameter, outer ring raceway band taper with traditional biserial cylinder difference, and bores It is consistent with inner ring internal diameter taper direction to spend direction.

It the advantage is that：

Compared with traditional structure, the utility model is simple in construction, easy disassembly, improves load and the life-span of bearing. In the case that axle is the conical surface, it is especially suitable for using the utility model.

The utility model simplifies the structure of bearing, and inner assembly not dismantle by the sequence of sanqu songs within a particular musical mode, convenience.Can add roller length and Grain number, the way of contact of roller and outer ring raceway is improved, so as to improve the rated load of bearing.Key is outer raceway band cone Degree can compensate for inner ring deformation it is inconsistent caused by bearing or so end clearance it is poor, extend the life-span of bearing.Outer ring raceway band is bored It is poor that degree can compensate for the inconsistent caused bearing of inner ring deformation or so end clearance.

Brief description of the drawings

Embodiment

A kind of Biserial cylindrical roller bearing for being adapted for mount on conical surface axle, including outer ring 1 and inner ring 2.

Two integrated cages 3 are set up in parallel between outer ring 1 and inner ring 2, multiple circles are installed on each integrated cage 3 Post roller 4, the raceway of outer ring 1 band taper, and taper direction is consistent with the internal diameter taper direction of inner ring 2.

Two ends of intermediate beam of integrated cage 3 are respectively equipped with four lock points 5 in the outer radius of integrated cage 3.

Integrated cage 3 uses interior guiding, internal diameter and the outer diameter contact of inner ring 2 of integrated cage 3.

First integrated cage 3 is attached on inner ring 2, then cylindrical roller 4 is pressed at the lock point 5 of the external diameter of integrated cage 3 Enter, as shown in A directions in Fig. 5, so as to form bearing inner assembly, finally load onto outer ring 1.
