Description
Technical Field
The utility model belongs to the technical field of machinery, and particularly relates to a step-type bearing mounting device.
Background
The step-shaped bearing is a bearing with a step-shaped section, the mounting end face of the bearing is also of a step shape matched with the bearing, the bearing is required to be completely clamped into a bearing mounting hole during mounting due to the requirements of sealing and accuracy, manpower is difficult to realize, an auxiliary tool is directly used for applying force on the bearing, the direction and the force are difficult to control, and the bearing is easy to damage.
Disclosure of Invention
In order to overcome the technical defects in the prior art, the utility model discloses a step-type bearing installation device.
The utility model discloses a step-type bearing mounting device, which comprises a pull rod, a retaining device positioned at one end of the pull rod, a nut arranged on the pull rod in a threaded manner, and a sleeve arranged between the nut and the retaining device, wherein the outer diameter of the sleeve is smaller than that of a bearing mounting hole, and the retaining device is used for clamping the mounting device on a bearing carrier outside the bearing mounting hole.
Preferably, the nut is a butterfly nut.
Preferably, the retaining device is an annular groove which is fixed at the tail end of the pull rod and symmetrically distributed around the pull rod shaft, and the radius of the annular groove is larger than that of the bearing mounting hole.
The step-type bearing mounting device can be used for manually assisting in mounting the step-type bearing, and the bearing is always aligned to the bearing mounting hole in the mounting process, so that the mounting process is convenient, labor-saving, safe and efficient.
Drawings
FIG. 1 is a schematic view of an embodiment of a step bearing mounting device according to the present utility model;
FIG. 2 is a schematic cross-sectional view of one embodiment of a stepped bearing mounting apparatus according to the present utility model; the reference numerals in the figures are:
1-pull rod, 2-bearing, 3-bearing carrier, 4-sleeve, 5-nut, 6-backstop.
Detailed Description
The following describes the embodiments of the present utility model in further detail with reference to the accompanying drawings.
The stepped bearing mounting device comprises a pull rod 1, a retaining device 6 positioned at one end of the pull rod, a nut 5 which is arranged on the pull rod in a threaded manner, and a sleeve 4 arranged between the nut and the retaining device, wherein the outer diameter of the sleeve is smaller than that of a bearing mounting hole, and the retaining device is used for clamping the mounting device on a bearing carrier outside the bearing mounting hole.
When in use, as shown in fig. 1, the nut 5 and the sleeve 4 are firstly removed from the pull rod 1, the pull rod passes through the bearing mounting hole on the bearing carrier 3, the pull rod cannot completely pass through the bearing mounting hole due to the effect of the retaining device, then the bearing 2 to be mounted is sleeved on the pull rod through the through hole in the center of the bearing, and then the sleeve is sleeved and the nut is screwed on in sequence.
In the embodiment shown in fig. 1, the retaining means is a collar groove around the drawbar secured to the end of the drawbar, the groove having a radius greater than the radius of the bearing mounting bore. The retaining device can also be a retaining plate arranged at the tail end of the pull rod, and annular supporting walls are arranged at the edges of the retaining plate and are all positioned at the outer sides of the bearing mounting holes.
In both of the above-mentioned retaining devices, a certain space is formed below the bearing mounting hole, so as to accommodate a protruding portion of the bearing protruding below the bearing carrier 3 when the bearing is mounted, as shown in fig. 1.
When the bearing 2 is installed, the nut 5 is gradually screwed in, the sleeve is extruded downwards, the sleeve gradually extrudes the bearing into the bearing installation hole because the outer diameter of the sleeve 4 is smaller than the bearing installation hole, the bearing cannot drop downwards from the bearing installation hole because the bearing installation hole and the bearing are in a step shape with the upper part being large and the lower part being small, the nut and the pull rod are connected through threads, the interval between the nut and the retaining device is continuously reduced because the nut is rotated downwards, and the retaining device 6 also can continuously compress the interval between the bearing 2 and the bearing installation hole upwards to be matched with the nut, so that the bearing is completely embedded into the bearing installation hole.
To facilitate rotation of the nut, as shown in fig. 1, the nut may be a wing nut.
After the bearing is installed, the nut is reversely rotated to withdraw from the pull rod, the sleeve is taken out, the pull rod is withdrawn from the through hole in the center of the bearing from top to bottom, and the installation device is detached from the bearing.
The step-type bearing mounting device can be used for manually assisting in mounting the step-type bearing, and the bearing is always aligned to the bearing mounting hole in the mounting process, so that the mounting process is convenient, labor-saving, safe and efficient.
The foregoing description of the preferred embodiments of the present utility model is not obvious contradiction or on the premise of a certain preferred embodiment, but all the preferred embodiments can be used in any overlapped combination, and the embodiments and specific parameters in the embodiments are only for clearly describing the utility model verification process of the inventor and are not intended to limit the scope of the utility model, and the scope of the utility model is still subject to the claims, and all equivalent structural changes made by applying the specification and the content of the drawings of the present utility model are included in the scope of the utility model.
