Abstract
The application is related to a kind of bearing block position limiting structure, including tubing string axle, bearing, bearing block, upper shell, lower house and locating part, the upper shell is connected to form inner chamber with lower house, the inner surface of the bearing block is connected with bearing fit, the outer surface of bearing block is connected with lower house, it is characterized in that, locating part is provided between the bearing block and upper shell, the upper shell is provided with the through hole coordinated with locating part, and through hole elastic compression of the locating part away from bearing block one end and upper shell is connected.By setting nonmetallic locating part, bearing block play is prevented, vibration damping eliminates abnormal sound；The conventional wavy spring of substitution, reduces the interference to sensor signal；Avoid bearing block pressure injustice and bearing clamping stagnation abnormal sound occur；By multiple locating parts and effective cooperation of upper shell and the cooperation of O-ring and upper shell groove, stable bearing seat prevents play, is effectively isolated steering column worm and worm wheel oil seborrhea and goes out contaminant sensor.
Description
Technical field
The utility model is related to automobile steering device field, specifically, being related to a kind of bearing block position limiting structure.
Background technology
In the prior art, to use wavy spring packing ring fixing bearing holder structure, wavy spring packing ring is metalwork, cost more
Height, influence sensor performance can be moved installed in housing, and wavy spring radial-play easily produces abnormal sound in addition, can further make to turn
Go out contaminant sensor to post worm and worm wheel oil seborrhea.
The content of the invention
The purpose of this utility model will solve above-mentioned problem of the prior art there is provided a kind of bearing block position limiting structure, lead to
The utilization of this bearing block position limiting structure is crossed, bearing block play is prevented, passed so as to isolate the seborrhea of steering column worm and worm wheel oil and go out pollution
Sensor.
It is as follows in order to solve prior art problem the technical solution adopted in the utility model：
A kind of bearing block position limiting structure, including tubing string axle, bearing, bearing block, upper shell, lower house and locating part, it is described
Upper shell is connected to form inner chamber with lower house, and the inner surface of the bearing block is connected with bearing fit, the appearance of bearing block
Face is connected with lower house, and locating part is provided between the bearing block and upper shell, and the upper shell is provided with and locating part
The through hole of cooperation, through hole elastic compression of the locating part away from bearing block one end and upper shell is connected.
Further, it is connected in order to significantly more efficient with upper casing resilient compression, and does not influence sensor signal, institute
Locating part is stated for non-metal elastomers.
Further, in order to preferably play a part of preventing bearing block play, number at least two of the locating part；
And the through hole that at least two coordinates with locating part is evenly distributed with upper shell.
Further, the locating part is balanced relative to bearing block axially loaded and set.
Further, the locating part is boss, cylinder, cuboid, cube or round platform.
Further, the locating part is boss, and boss bottom is provided with groove.
Further, the outer surface of the bearing block is provided with groove, the groove and is provided with O-ring seal.
Compared with prior art, the utility model has the advantages that：
1. by setting nonmetallic locating part, preventing bearing block play, vibration damping eliminates abnormal sound；
2. the conventional wavy spring of substitution, reduces the interference to sensor signal；
3. avoiding bearing block pressure injustice there is bearing clamping stagnation abnormal sound；
4. pass through multiple locating parts and effective cooperation of upper shell and the cooperation of O-ring and upper shell groove, stable bearing
Seat, prevents play, is effectively isolated steering column worm and worm wheel oil seborrhea and goes out contaminant sensor.
