Abstract
The utility model discloses a cluster bearing device, comprises a clamp body, anchor clamps body upper portion is equipped with pressure equipment mechanism, the anchor clamps body is gone up and is set up and bearing excircle size assorted bearing guiding hole, bearing guiding hole bottom surface center department on the anchor clamps bodies set up with pump shaft size assorted axle guide to the hole, bearing guiding hole and bearing excircle clearance fit, axle guide is to hole and pump shaft clearance fit. The utility model discloses the cluster bearing device who takes dual direction can prevent effectively that the bearing from dropping, guarantees the assembly precision.
Description
Technical field
The utility model relates to technical field of tooling clamps, particularly a kind of string bearing arrangement.
Background technology
Water pump complement uses two kinds of bearings, and one is shaft connecting bearing, and one is release bearing.When assembling release bearing, lower bearing first need be contained on pump shaft, be called string bearing.Bearing is important precise part, does not allow bearing to fall when running in bearings.Normal employing, with lower device running in bearings, is first inserted pump shaft small end in clamp body endoporus, bearing is loaded in pressure head locating hole.Be evenly equipped with resilient plunger in pressure head locating hole bearing is clipped in pressure head.Be provided with groove in pressure head, pressure assembling force acts on bearing inner race.Can ensure that bearing roller does not stress.Use the drawback of this device to be: steel ball not easily clamps bearing, easily makes bearing drop, and is pressing down in process, and bearing easily tilts, the active force that after bearing tilts, pressure head acts on bearing inner race is uneven, easily damages pump shaft or bearing by pressure.Bearing press-fitting device disclosed in prior art, bearing press-fitting device disclosed in CN200820159744.8, its weak point is: bearing is placed in seaming chuck and easily falls or tilt, and tilts and pull the pump housing dead eye when causing press-in, reduces bearing service life.
Utility model content
In view of this, the purpose of this utility model is for the deficiencies in the prior art, provides a kind of string bearing arrangement, uses the string devices of the dual guiding of band effectively to prevent bearing from dropping, ensures assembly precision.
For achieving the above object, the utility model is by the following technical solutions: a kind of string bearing arrangement, comprise clamp body, described clamp body top is provided with press-loading device, described clamp body is arranged the bearing pilot hole matched with bearing top circle, the bearing pilot hole end face center of described clamp body arranges the axially oriented hole matched with pump shaft.
Described bearing pilot hole and bearing top circle matched in clearance.
Described axially oriented hole and pump shaft matched in clearance.
Described press-loading device comprises and is arranged on the power source on clamp body top and the pressure head of drive thereof, is provided with the groove matched with pump shaft in described pressure head.
Described pressure head diameter is not more than the external diameter of bearing inner race.
Described bearing pilot hole, axially oriented hole are coaxial.
The beneficial effects of the utility model are: clamp body designs two guide-localization holes, and one is the little pilot hole (i.e. axially oriented hole) coordinated with pump shaft small end cylindrical, and another coordinates the large pilot hole (i.e. bearing pilot hole) of locating.Little pilot hole location pump shaft, large pilot hole guide bearing.Pump shaft small end is inserted in the little pilot hole of clamp body, bearing is loaded in the large pilot hole of clamp body.Now bearing and pump shaft are directed to all, and power source band dynamic head presses down, and pressure assembling force acts on bearing inner race, can ensure that bearing roller does not stress, thus can not bearing roller be damaged, pressure head continues to press down until on bearing press-in pump shaft step, take off pump shaft component.Pump shaft of the present utility model and bearing are all placed on clamp body, axially oriented hole and bearing pilot hole make bearing and the dual guiding of pump shaft, pump shaft and bearing can not rock and tilt, bearing is press-fiting in process, pressure to act on bearing inner race and uniform force by pressure head completely, bearing roller can not be stressed, can not damage.
