Abstract
The utility model relates to a top roll bearing with a gear and an isolating elastic, in particular to a textile cradle extension institution and pertains to the textile machine parts technical field. The utility model mainly adopts the gear to be arranged on the bearing shell. A retainer of a roll ball, a roller and a needle roll are covered on the central axis and an isolating elastic is arranged within the retainer and is divided into isolated elastic paths. The roller is integrated with the retainer of the roll ball and the peripheral surface of the central axis is provided with a central axis groove and a groove and a roll path are arranged within the peripheral surface of the internal wall of the bearing shell. The roll ball is arranged within the grooves and the central axis groove while the roller and the needle roll is arranged within the roll path. The utility model has the advantages of a simple, compact and reasonable structure. Due to the isolated elastic arranged within the retainer of the roller, the roller arranged with an isolated elastic is integrated with the retainer of the roll ball to be conveniently arranged the roll ball and needle roll, which not only reduce the clearance of the top roll bearing and increase the stationarity of the utility model, but also prolong the service life by one to two times. The utility model takes the excircle gear as a rotary point to prevent the bearing from sliding or stopping when rotating.
Description
Technical field
The utility model relates to a kind of upper roller bearing that has gear and isolation bar, specifically is used for the reel cage drafter of weaving loom, belongs to the textile machinery accessories technical field.
Background technology
At present, existing upper roller bearing adopts the end at mandrel to be provided with two ball retainers at a distance of certain distance, and ball is housed in the retainer, and retainer and ball outside are with cartridge housing.Cartridge housing one end is equipped with sealing cap, and the one end has the dust ring that is loaded between mandrel and the cartridge housing.The side face of mandrel one end is provided with two circular arc concave shape raceway grooves, and cartridge housing inwall side face is provided with a circular arc raceway groove relative with raceway groove.Ball in the retainer simultaneously is embedded in the raceway groove, and the inwall of another side and cartridge housing is tangent.When bearing rotated, the movement locus of ball and the tangent dessert of cartridge housing inwall was a circumference.In other words, promptly mandrel one end has two for the raceway groove of ball as roller track, and the inwall of cartridge housing has a raceway groove, a raceway.
Because ball is that point contacts with raceway, when high speed rotating, ball is big in the normal pressure of radially passing to raceway.In contrast, ball is that face contacts with raceway, and the normal pressure of suffered ball is little, thereby raceway groove is not easy to wear.Because raceway is easy to wearing and tearing, when radial and axial play increases to a certain degree, have only and whole top roller is scrapped and changed, this just badly influences the service life of upper roller bearing.
Through testing: actual measurement average data end-play is: 0.02mm; End-play is: 0.11mm.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, changes raceway groove at the cartridge housing inwall along the side face raceway thereby provide a kind of, and raceway groove changes raceway into; In the retainer of roller, isolation bar is set, the roller and the ball retainer that are provided with isolation bar are connected as a single entity, be convenient to the assembling of roller or needle roller; The play of upper roller bearing is reduced greatly, and stationarity is good, can increase the service life greatly; Knucle-gear is a run-on point in addition, when gear prevents that bearing from skidding at the volley or making a pause when rotating.
Main solution of the present utility model is achieved in that
The utility model mainly is made of mandrel and the bearing that is positioned at the symmetrical configuration at its two ends, and the structure of bearings at both ends is identical.Its bearing comprises mandrel, in the mandrel outside cartridge housing is housed; Mandrel one end is equipped with sealing cap, and feature is that gear is contained on the cartridge housing, with the cartridge housing tight fit, be set with ball retainer and roller or cages for needle on the mandrel, in the retainer of roller or needle roller isolation bar is set, isolation bar is divided into 2～3 and isolates chewiness, is connected as a single entity with ball retainer; Mandrel is provided with the mandrel raceway groove along side face, and the cartridge housing inwall is provided with raceway groove and raceway along side face, and raceway groove is relative with the mandrel raceway groove, and ball is contained in raceway groove and the mandrel raceway groove in the retainer, and roller or needle roller are contained in the raceway; 2～3 rollers or needle roller are contained in 2～3 respectively isolates in the chewiness, and 2～3 rollers or needle roller move in raceway.
The utility model ball diameter is: Φ 2mm～Φ 5mm; Roller or needle roller diameter are: Φ 1.5mm～Φ 5mm; Roller or needle roller length are: 3mm～18mm.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Owing to change raceway groove at the cartridge housing inwall into along the side face raceway, raceway groove changes raceway into, in the retainer of roller isolation bar is set, and the roller and the ball retainer that are provided with isolation bar are connected as a single entity, and is convenient to the assembling of roller or needle roller; The play of upper roller bearing is reduced greatly, and stationarity is good, and can improve 1～2 times of service life; Knucle-gear is a run-on point in addition, when gear prevents that bearing from skidding at the volley or making a pause when rotating.
