Abstract
The utility model provides a crossed roller bearing comprising an outer ring. The outer ring is divided into an upper outer ring and a lower outer ring which are laminated up and down; an outer ring limiting hole and an outer ring fixing hole are arranged at the edge of the outer ring; an inner ring is arranged at the inner side of the outer ring, and is of an integrated structure; and an inner ring fixing hole, a driver connection hole and a positioning pin hole are arranged at the edge of the inner ring. After the crossed roller bearing is provided with a pin roller and a space maintainer, the inner ring or the outer ring is fixedly connected with a crossed roller shaft ring, so that the inner ring or the outer ring and the crossed roller shaft ring can be prevented from being manually separated. Idler wheels are arranged in a crossed manner, so that one crossed idler wheel shaft ring can bear load in each direction. Compared with the traditional crossed roller bearing, the crossed roller bearing has the advantage that the rigidity is improved for 3-4 times. Meanwhile, the inner ring and outer ring of the crossed idler wheel bearing can be structured in a separated manner, so that the bearing gap can be adjusted. Even if the bearing gap is pre-loaded, the high precision rotation can be further obtained. The heat treatment of the outer ring uses the entire quenching process, and the inner ring uses an idler wheel surface high-frequency quenching process and can be connected by utilizing various structures.
Description
Technical field
The utility model relates to a kind of bearing, is to belong to mechanical field, particularly a kind of crossed roller bearing.
Background technique
Bearing is in mechanical transmission course, to work the parts of fixing and reducing the load friction factor.Also we can say, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in the power transmission process.Bearing is a kind of very important component in the contemporary machinery.Its major function is the supported mechanical solid of rotation, in order to the mechanical load friction factor of reduction equipment in transmission process.
The inner ring of the normal crossing roller bearing on the existing market is circular, and its connection is cooperating together through axle and annulus.But axle is installed on the bearing as independent parts, when installing, a lot of installation procedures will be arranged on the one hand, and will be with reference to a lot of parameters.And, in use, owing to the flaw of installing produces the problem in the use, the normal operation of influence machinery.Simultaneously, when bearing need with other parts (as: retarder) when being connected, a mounting connection structure just must be installed again to satisfy the requirement that connects between bearing and rotating shaft.The installation of a plurality of different parts and repeated multiple times keeps away the unstability that the error unavoidably installed and the annexation between the different parts bring for this mechanical running, and also ten/inconvenience repeatedly is installed.

The inner ring of the utility model crossed roller bearing or outer ring behind pack into roller and spacing holder, are fixed together with the decussation roller axle collar, and be disconnected from each other to prevent.Because roller is cross arrangement, therefore only just can bear the load of all directions with the 1 cover decussation roller axle collar, to compare with traditional model, rigidity improves 3～4 times.Simultaneously, because of crossed roller bearing inner ring or outer ring are two structures cut apart, the bearing play can be adjusted, even be applied in preload, also can obtain to rotatablely move accurately.
The utility model crossed roller bearing also is to adopt the outer ring Splittable; The inner ring overall structure; Compare with the standard crossed roller bearing, be processed with a lot of mounting holes on the inner and outer ring, especially inner ring; The installation tapped hole that three layers of different size and quantity are arranged from outside to inside, this be in appearance with maximum other of basic model crossed roller bearing.Material all adopts the GCr15 Bearing Steel, and integral quenching technology is adopted in outer ring heat treatment, and inner ring adopts the raceway face quenching technology, and this is to compare maximum difference part with normal crossing roller bearing technology.This design method, can be practical multiple structure connects, and particularly is connected between the arm of mechanism hand and the arm.
The utility model crossed roller bearing outer ring on bearing reaches down, and the outer ring is equipped with inner ring; Inner ring reaches down through cross roller and last outer ring, and the outer ring is connected; On inner ring, be provided with driver fixed hole and inner ring fixed hole, the quantity of inner ring fixed hole can change according to the needs of rotating shaft, and the quantity of driver fixed hole also can change according to the needs of driver connecting end; Bearing can be connected with rotating shaft and retarder once simultaneously; Avoided repeatedly adding axle operation of bringing of installing and the alignment error of therefore bringing, guaranteed mechanical normal operation, simultaneously; The utility model crossed roller bearing also is provided with locating stud on inner ring, let bearing installation and operation more firmly and safety.
Inner ring of the utility model or outer ring behind pack into roller and spacing holder, are fixed together with the decussation roller axle collar, prevent disconnected from each other.Because roller is cross arrangement, only just can bear the load of all directions with the 1 cover decussation roller axle collar, to compare with traditional model, rigidity improves 3～4 times.Simultaneously, because of crossed roller bearing inner ring or outer ring are two structures cut apart, the bearing play can be adjusted, even be applied in preload, also can obtain to rotatablely move accurately.Integral quenching technology is adopted in outer ring heat treatment, and inner ring adopts the raceway face quenching technology, can use multiple structure to connect.
