Abstract
A kind of bearing unit with profile of tooth seat, comprise bearing (1) and profile of tooth seat (2), it is characterized in that: profile of tooth seat (2) forms the step hole (2) running through profile of tooth seat (2) two ends, the outer ring of bearing (1) is plugged in the macropore of profile of tooth seat (2) step hole (2), one end face of bearing (1) outer ring leans against on the step surface of step hole (2), on other end and has been pressed against jump ring (3), and jump ring (3) holding is on the madial wall of step hole (2) macropore; The outer wall of described profile of tooth seat (2) forms the teeth groove (23) of some roads annular, profile of tooth seat (2) outer wall of profile of tooth seat (2) step hole (2) macropore side end face forms the rib (22) of annular.The bearing unit that it adopts is scrapped conveniently can take off worn bearing at bearing, more renews bearing, thus profile of tooth seat can be reused, and improves the utilization of resources.
Description
Technical field:
The utility model relates to the technical field of bearing, more specifically to a kind of bearing unit with profile of tooth seat.
Background technique:
Existing elevator bearing unit is interference fit holding double row bearing in the endoporus of profile of tooth seat, matched with the line belt of elevator by profile of tooth seat simultaneously, and adopt the bearing of interference fit and profile of tooth seat to be closely fixed together, bearing generally cannot take off from profile of tooth seat, thus bearing to scrap be to change a whole set of bearing unit.
Model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and provides a kind of bearing unit with profile of tooth seat, and it without the need to changing a whole set of bearing unit, improves the utilization of resources when bearing is scrapped.
Technology solution of the present utility model is as follows:
A kind of bearing unit with profile of tooth seat, comprise bearing and profile of tooth seat, profile of tooth seat forms the step hole running through profile of tooth seat two ends, the outer ring of bearing is plugged in the macropore of profile of tooth seat step hole, one end face of bearing outer ring leans against on the step surface of step hole, on other end and has been pressed against jump ring, and jump ring holding is on the madial wall of step hole macropore;
The outer wall of described profile of tooth seat forms the teeth groove of some roads annular, the profile of tooth seat outer wall of profile of tooth seat step hole macropore side end face forms the rib of annular.
Described bearing is provided with two, and bearing also comes in the step hole of profile of tooth seat, and the length of two bearings is less than rib and deviates from spacing between the end face of profile of tooth seat end face side and profile of tooth seat step hole step surface.
Described teeth groove is evenly distributed on profile of tooth seat along profile of tooth seat central axis, and teeth groove deviates from the profile of tooth seat outer side wall between the end face of profile of tooth seat end face side and profile of tooth seat step hole step surface at rib.
The hole diameter of described profile of tooth seat step hole is greater than the external diameter of bearing inner race.
The beneficial effects of the utility model are:
1, the bearing unit that it adopts is scrapped conveniently can take off worn bearing at bearing, more renew bearing, thus profile of tooth seat can be reused, and improves the utilization of resources.
2, it is provided with baffle plate in the side of profile of tooth seat, facilitates the installation of bearing, can not cut open the teeth groove on bad profile of tooth seat in installation process.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure: 1, bearing; 2, profile of tooth seat; 3, jump ring; 21, step hole; 22, rib; 23, teeth groove.
Embodiment:
Embodiment: as shown in Figure 1, a kind of bearing unit with profile of tooth seat, comprise bearing 1 and profile of tooth seat 2, profile of tooth seat 2 forms the step hole 2 running through profile of tooth seat 2 two ends, the outer ring of bearing 1 is plugged in the macropore of profile of tooth seat 2 step hole 2, one end face of bearing 1 outer ring leans against on the step surface of step hole 2, on other end and has been pressed against jump ring 3, and jump ring 3 holding is on the madial wall of step hole 2 macropore;
The outer wall of described profile of tooth seat 2 forms the teeth groove 23 of some roads annular, profile of tooth seat 2 outer wall of profile of tooth seat 2 step hole 2 macropore side end face forms the rib 22 of annular.
Described bearing 1 is provided with two, and bearing 1 also comes in the step hole 2 of profile of tooth seat 2, and the length of two bearings 1 is less than rib 22 and deviates from spacing between the end face of profile of tooth seat 2 end face side and profile of tooth seat 2 step hole 21 step surface.
Described teeth groove 23 is evenly distributed on profile of tooth seat 2 along profile of tooth seat 2 central axis, and teeth groove 23 deviates from profile of tooth seat 2 outer side wall between the end face of profile of tooth seat 2 end face side and profile of tooth seat 2 step hole 21 step surface at rib 22.
The hole diameter of described profile of tooth seat 2 step hole 21 is greater than the external diameter of bearing 1 inner ring.
Working principle: the utility model only need dismantle the bearing 1 that jump ring 3 just can more renew, thus profile of tooth seat 2 can be reused, improve the utilization of resources, be simultaneously provided with baffle plate 22 in the side of profile of tooth seat 2, when using copper rod to knock in bearing during installation, can prevent copper rod from knocking teeth groove 23 on profile of tooth seat 2.
