Abstract
The utility model relates to a bearing for textile machinery and is applied to the field of the textile machinery. The bearing comprises an outer ring, cylindrical rolling bodies, an inner ring and shield covers. The cylindrical rolling bodies are installed between the outer ring and the inner ring and evenly arranged in a raceway between the outer ring and the inner ring. The bearing is characterized in that a first shield cover and the inner ring are integrated. A second shield cover is provided with threaded holes. Screws penetrate through the threaded holes to combine the second shield cover and the inner ring into a whole. The bearing for the textile machinery can well improve phenomena of fall-off of the shield cover of the bearing. Due to quantity increase of the cylindrical rolling bodies, load on each roller can be reduced a little, radial force of the inner ring and the outer ring on the rolling bodies arranged in the bearing can be decreased, axial movement of the rolling bodies is also reduced, and consequently phenomena of fall-off of the shield cover is improved. At the same time, bearing capacity of the bearing for the textile machinery is increased and service life of the bearing is prolonged.
Description
Technical field
The present invention relates to a kind of textile manufacturing machine bearing, be applied to field of textile machinery.
Background technique
Being used for the textile manufacturing machine bearing mainly is made up of outer ring, inner ring, rolling element, two doors, grease etc.Be employed between outer ring and the inner ring rolling element is installed; Rolling element adopts cylinder type, is evenly distributed between outer ring and the inner ring, and two doors and inner ring closely couple together with screw; Door plays dustproof and prevents that leaking outside effect of grease, grease from playing lubricated and effect such as formation oil film.This bearing is assemblied on the textile manufacturing machine need bear bigger load; Because axial force will cause axial float bigger more greatly during textile manufacturing machine work; The rolling element axial float can make screw become loosening, causes that grade limit falls to cover phenomenon, and dust and impurity can get into inner ring and also can spill with grease simultaneously like this; Thereby cause bearing failure, influenced the working life of bearing.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency; A kind of textile manufacturing machine bearing is provided; Under the prerequisite that the base dimension of bearing remains unchanged, on the one hand, improved bearing because of receiving axial force; Cause that axial float falls the phenomenon of door, on the other hand because the increase of rolling element can increase bearing capacity by more uniform bearing load.
According to technological scheme provided by the invention, a kind of textile manufacturing machine bearing comprises outer ring, cylinder type rolling element, inner ring; The cylinder type rolling element is installed between outer ring and inner ring; The cylinder type rolling element is evenly distributed in the raceway groove of outer ring and inner ring; Characteristic is: said first door and inner ring fuse, and second door is provided with tapped hole, and screw links into an integrated entity second door and inner ring through tapped hole.
The external diameter of said outer ring is φ 88mm, and the outer ring internal diameter is φ 62.38mm, and width dimensions is 6.8mm.
The external diameter of said inner ring is φ 53mm, and internal diameter is φ 17mm, and shelves limit external diameter is φ 56mm, and shelves hem width degree is 1.25mm, and the internal diameter of through hole is φ 8mm, and width is 6mm.
The external diameter of said second door is φ 56mm, and width is 1.25mm, and tapped hole is M8 * 3mm.
The present invention compares with original structure and has the following advantages:
The present invention is owing to adopt first door and inner ring to fuse, and second door connects inner ring with screw, can well improve the phenomenon of falling door of bearing like this; Because cylinder type rolling element quantity increases; The load that receives of each roller can reduce a bit like this; The axial force that rolling element in the bearing receives Internal and external cycle reduces; Thereby axial float also can reduce the phenomenon of having improved lid like this, has also improved the bearing capacity of textile manufacturing machine bearing simultaneously, the working life of having improved bearing.

Fig. 2 is a structure side view of the present invention.
Fig. 3 is a screw schematic representation of the present invention.
Embodiment
Following the present invention will combine the embodiment in the accompanying drawing to further describe:
As shown in Figure 1, comprise compositions such as outer ring 1, cylinder type rolling element 2, inner ring 3, first door 6, second door 4, screw 5.Lean on cylinder type rolling element 2 to connect between outer ring 1 and the inner ring 3; Cylinder type rolling element 2 is evenly distributed in the raceway groove of outer ring 1 and inner ring 3; First door 6 fuses with inner ring 3; Said second door 4 is provided with tapped hole, and screw 5 links into an integrated entity second door 4 through tapped hole with inner ring 3.Said cylinder type rolling element 2 quantity can increase, and in outer ring 1 and inner ring 3, inject grease.
One embodiment of the present of invention, the external diameter of its outer ring 1 are φ 88mm, and the outer ring internal diameter is φ 62.38mm, and width dimensions is 6.8mm.
The external diameter of inner ring 3 is φ 53mm, and internal diameter is φ 17mm, and shelves limit external diameter is φ 56mm, and shelves hem width degree is 1.25mm, and the internal diameter of through hole is φ 8mm, and width is 6mm.
The external diameter of second door 4 is φ 56mm, and width is 1.25mm, and tapped hole is M8 * 3 mm.
This structure has increased the quantity of cylindrical roller under the prerequisite that guarantees fabric mechanical bearing torque demand; Increased the sliding friction area of cylindrical roller and inner ring cylindrical and outer ring inner headed face; Reduced the play of the axial force of the inner rolling element of bearing to door; Improve the bearing capacity of fabric mechanical bearing, adopted bearing inner race and the conjuncted structure in shelves limit that increased the working life of fabric mechanical bearing.
