Abstract
The utility model discloses a limiting device on a speed reducer. The limiting device on the speed reducer comprises a limiting block, a stepped shaft, a bearing, a connecting flange and a clamping ring, wherein one end of the limiting block is arranged on a half shaft and is in interference fit with the half shaft; the other end of the limiting block is connected with the stepped shaft; the stepped shaft is arranged on a bearing inner race and is in interference fit with the bearing inner race; a bearing outer race is arranged on an inner hole of the connecting flange, is in transition fit with the inner hole of the connecting flange, and is clamped by the clamping ring, so that the bearing outer race can be prevented from moving; and the connecting flange is fixed on an end cap. The limiting device on the speed reducer is simple in structure and convenient to machine; movement of the half shaft can be limited; and a potential phenomenon that the limiting block and the stepped shaft relatively slide and rub with each other is avoided. The limiting device on the speed reducer can be widely applied to a hub reduction gear of an overload vehicle.
Description
Technical field
the utility model relates to a kind of limit stoper, is the limit stoper on a kind of retarder specifically.
Background technique
at present, the wheel reductor of heavy-duty vehicle adopts planetary gear speed reducing mechanism more both at home and abroad, and it is large that this structure has velocity ratio excursion, compact structure, and bearing capacity is high, train stable drive, shock resistance and anti-vibration ability are strong, the advantages such as reliable operation.Wheel reductor is substantially all that plural serial stage becomes the train that velocity ratio is large, causes like this semiaxis rotating speed high, and is not easy to spacingly, even causes relative sliding friction, causes whole wheel reductor oil temperature too high, has reduced wheel reductor working life.This problem is anxious to be resolved.
Summary of the invention
object to be solved in the utility model is in order to solve the problems of the technologies described above, and the limit stoper on a kind of retarder is provided, and this apparatus structure is simple, easy to process, and can limit well semiaxis play.
Realizing the technical solution of the utility model is: the limit stoper on a kind of retarder, comprises limiting stopper, multidiameter shaft, bearing, adpting flange, snap ring; Described limiting stopper one end is installed on semiaxis, interference fit, and the other end is connected with multidiameter shaft; Described multidiameter shaft is installed on bearing inner race, interference fit; Described bearing outer ring is installed on adpting flange endoporus, transition fit, and blocked by snap ring, prevent play; Described adpting flange is fixed on end cap.
Described adpting flange is fixed on end cap with the screw with spring pad.
Porose on described adpting flange, so that lubricant oil enters inner chamber lubricating bearings by hole, avoid Bearing Temperature.
Described limiting stopper appearance has wearing layer, makes it durable.
Described bearing is tapered roller bearing.
The utility model beneficial effect is:
1, limiting stopper and multidiameter shaft can together with rotatablely move, not only limited semiaxis left and right play, and avoided because of both relatively friction make the too high phenomenon of Wheel-side planetary reducer oil temperature.
2, the utlity model has reasonable in design, simple in structure, be convenient to the advantages such as processing.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model;
Fig. 2 is adpting flange schematic diagram of the present utility model;
Fig. 3 is the A-A view of Fig. 2;
Fig. 4 is multidiameter shaft cross-sectional schematic of the present utility model.
In figure: 1-limiting stopper, 2-multidiameter shaft, 3-bearing, 4-bolt, 5-spring washer, 6-end cap, 7-adpting flange, 8-snap ring, 9-semiaxis.
Embodiment
as shown in Figure 1 to 4: the limit stoper on a kind of retarder, comprises limiting stopper 1, multidiameter shaft 2, bearing 3, adpting flange 7, snap ring 8.One end of described limiting stopper 1 is installed on semiaxis 9, interference fit, and the other end is connected with multidiameter shaft 2; Described multidiameter shaft 2 is installed on bearing 3 inner rings, interference fit; Described bearing 3 outer rings are installed on adpting flange 7 endoporus, and transition fit, is blocked by snap ring 8, prevents play; Described adpting flange 7 is fixed on end cap 6 by bolt 4, spring washer 5; Bearing 3 selects that tapered roller bearing can bear radially, axial larger load.Porose on described adpting flange 7, so that lubricant oil enters inner chamber lubricating bearings 3 by hole, avoid bearing 3 excess Temperatures.Described limiting stopper 1 appearance also has wearing layer, makes it durable.Due to the existence of the factors such as processing and assembling, semiaxis 9 is to be connected with motor elasticity by coupling.
During the utility model work, semiaxis 9 is relative movement with end cap 6, and limiting stopper 1 is installed on semiaxis 9, multidiameter shaft 2, bearing 3, bolt 4, spring washer 5, adpting flange 7, snap ring 8 assemblies such as grade are installed on end cap 6, therefore limiting stopper 1 may produce relative movement with multidiameter shaft 2, but limiting stopper 1 is during in company with semiaxis 9 play, limiting stopper 1 rotates together with multidiameter shaft 2, whole like this relative movement is just converted to the relative movement of bearing 3 Internal and external cycles, equally, relative sliding friction is also converted to the object that rolling friction has reached limit stoper, limited semiaxis left and right play, avoided relatively rubbing and making Wheel-side planetary reducer oil temperature too high because of both.
Claims (5)
1. the limit stoper on retarder, is characterized in that: comprise limiting stopper, multidiameter shaft, bearing, adpting flange, snap ring; Described limiting stopper one end is installed on semiaxis, interference fit, and the other end is connected with multidiameter shaft; Described multidiameter shaft is installed on bearing inner race, interference fit; Described bearing outer ring is installed on adpting flange endoporus, transition fit, and blocked by snap ring, prevent play; Described adpting flange is fixed on end cap.
