Abstract
The utility model discloses a thrust shaft guide sleeve. The guide sleeve is characterized in that a plurality of support bars are arranged on the outer wall of the guide sleeve and extend along the axial direction of the guide sleeve; and a plurality of through grooves are uniformly distributed on the outer wall of the guide sleeve. The guide sleeve has the advantages that friction between a thrust shaft and the thrust shaft guide sleeve can be reduced and the heat generated by friction can be effectively dissipated.
Description
Technical field
The utility model relates to the guide sleeve technical field.
Background technique
Thrust axis and the thrust axis guide sleeve between during relative movement, can produce larger frictional force, produce simultaneously larger heat, high temperature can cause accelerated wear test between thrust axis and the thrust axle sleeve, and the barrel of present thrust axis guide sleeve is generally solid, be difficult to dissipation of heat is gone out, have through hole on some guide sleeves because the barrel of guide sleeve and outside cooperation place remain and combine closely even have, also very difficult dissipation of heat is gone out.
The model utility content
The friction that can reduce between thrust axis and the thrust axis guide sleeve falls in the utility model, fricative heat effectively can be distributed.
The purpose of this utility model is come specific implementation by the following technical programs:
A kind of thrust axis guide sleeve is provided with supporting bar at described guide sleeve outer wall, and described supporting bar has many, extend axially along described guide sleeve,
Have groove at described guide sleeve outer wall, described groove has a plurality of, is evenly distributed on the outer wall of described guide sleeve.
Further, described supporting bar has four, evenly distributes around the outer wall of described guide sleeve.
Further, the outer wall of described supporting bar is arc surface, the axis of described arc surface and the dead in line of described guide sleeve.
Further, the sidewall of described supporting bar is arc surface, and the outer wall of described sidewall and described guide sleeve is tangent.
Further, be equipped with groove between per two supporting bars.
The utility model is by the design to groove and supporting bar on the thrust axis guide sleeve, reduced the area of contact between thrust axis and the thrust-bearing, and then reduced friction, the design of supporting bar and groove is then so that the groove that is used for dispelling the heat can be away from outside cooperation place, directly and contact with air, heat is fully distributed with air ventilation.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is the plan view of the described a kind of thrust axis guide sleeve of the utility model embodiment.
Fig. 2 is the side view of the described a kind of thrust axis guide sleeve of the utility model embodiment.
Fig. 3 is the sectional view of the described a kind of thrust axis guide sleeve of the utility model embodiment.
Embodiment
As Figure 1-3, the described a kind of thrust axis guide sleeve of the utility model embodiment is provided with 1 of support at the guide sleeve outer wall, and supporting bar 1 has many, extend axially along guide sleeve,
Have groove 2 at the guide sleeve outer wall, groove 2 has a plurality of, is evenly distributed on the outer wall of guide sleeve.
Supporting bar 1 has four, evenly distributes around the outer wall of guide sleeve.
The outer wall of supporting bar 1 is arc surface, the axis of arc surface and the dead in line of guide sleeve.
The sidewall of supporting bar 1 is arc surface, and the outer wall of sidewall and guide sleeve is tangent.
Be equipped with two grooves 2 between per two supporting bars 1, groove 2 extends around the guide sleeve outer wall, perhaps extends axially along guide sleeve.
The utility model is by the design to groove and supporting bar on the thrust axis guide sleeve, reduced the area of contact between thrust axis and the thrust-bearing, and then reduced friction, the design of supporting bar and groove is then so that the groove that is used for dispelling the heat can be away from outside cooperation place, directly and contact with air, heat is fully distributed with air ventilation.
