Abstract
The utility model belongs to the technical field of mechanical mounting, especially, adjusting structure of gear shaft bearing installation clearance. An adjusting structure of gear shaft bearing installation clearance, includes box and gland, gear shaft and bearing frame have in the box, being equipped with preceding support bearing between the front portion of gear shaft and the bearing frame, being equipped with back support bearing between the rear portion of gear shaft and the bearing frame, on the gear shaft, be equipped with the spacer between preceding support bearing and the back support bearing, the junction of box one end and gland is equipped with the adjusting shim that a plurality of double ring -shaped gasket made up and organizes, and is different to half ring -shaped gasket's with right thickness. The utility model provides an adjusting shim group can the effectual adjusting block of convenient and fast the installation clearance, the cost is low, time of having practiced thrift secondary operation, avoided secondary operation's risk, right according to half ring -shaped gasket of the different thickness of adjustment, can realize the accurate adjustment of multiunit scope, the realization accurate adjustment does under the inorganic processing conditions.
Description
Technical field
The utility model belongs to mechanical assembly technique field, especially a kind of adjust structure of gear shaft bearing assemblage gap.
Background technique
For the adjustment of gear shaft bearing assemblage gap, inconsistent due to each part machining tolerance, finally causes assembling post gap deviation larger.The method of traditional machining removing surplus is used to come adjusting play, workload is huge, waste time and energy, and also there is certain risk during secondary operations, as bad in centering or machining allowance controls badly will directly to affect the Adjustment effect of bearing play, under the situation particularly running into inorganic processing conditions, adjustment bearing play cannot realize.
Model utility content
The technical problems to be solved in the utility model is: based on the problems referred to above, provides a kind of adjust structure of gear shaft bearing assemblage gap, can avoid the risk of secondary operations, can realize again the precision adjustment in inorganic processing conditions situation lower bearing gap.
The utility model solves the technological scheme that its technical problem adopts: a kind of adjust structure of gear shaft bearing assemblage gap, comprise casing and gland, there is in described casing gear shaft and bearing support, front support bearing is provided with between the front portion of described gear shaft and bearing support, rear support bearing is provided with between the rear portion of gear shaft and bearing support, spacer is provided with on gear shaft, between front support bearing and rear support bearing, the joint of casing one end and gland is provided with the adjusting shims that some double annular gaskets are combined into, and the thickness for right semi-circular pad is different.
Further, described front support bearing is single row roller bearing, and described rear support bearing is Biserial cylindrical roller bearing.
Further, described semi-circular pad offers some fixed holes.Fixed hole is set, facilitates stationary half shape pad.
Further, the thickness of described semi-circular pad comprises 0.1mm, 0.2mm, 0.6mm, 1.0mm, 1.2mm and 1.6mm.
The beneficial effects of the utility model are: the adjusting shims in the utility model can the assemblage gap of convenient and swift effective adjustment bearing, cost is low, save the time of secondary operations, avoid the risk of secondary operations, according to the semi-circular pad pair of adjustment different-thickness, the precision adjustment of many class ranges can be realized, under inorganic processing conditions, also can realize accurate adjustment.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of a pair semi-circular pad in the utility model.
In figure: 1. casing, 2. gland, 3. gear shaft, 4. bearing support, 5. front support bearing, 6. rear support bearing, 7. spacer, 8. semi-circular pad, 9. adjusting shims, 10. fixed hole.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of adjust structure of gear shaft bearing assemblage gap, comprise casing 1 and gland 2, there is in casing 1 gear shaft 3 and bearing support 4, front support bearing 5 is provided with between the front portion of gear shaft 3 and bearing support 4, rear support bearing 6 is provided with between the rear portion of gear shaft 3 and bearing support 4, spacer 7 is provided with on gear shaft 3, between front support bearing 5 and rear support bearing 6, the joint of casing 1 one end and gland 2 is provided with the adjusting shims 9 that some double annular gaskets 8 are combined into, to different from the thickness of right semi-circular pad 8.Wherein, front support bearing 5 is single row roller bearing, and rear support bearing 6 is Biserial cylindrical roller bearing.
As shown in Figure 2, semi-circular pad 8 offers some fixed holes 10.The thickness 0.1mm that semi-circular pad 8 is conventional, 0.2mm, 0.6mm, 1.0mm, 1.2mm and 1.6mm.
During specific operation, gland 2 first navigates on casing 1 by two bolts, then the semi-circular pad 8 snapping in some is between right, these semi-circular pads 8 select certain thickness to according to actual conditions, adjust the semi-circular pad 8 of bearing assemblage gap to they being fixed by fixed hole 10 again, whole adjustment process is quick, convenient, has both avoided the risk of secondary operations, achieves again the precision adjustment in inorganic processing conditions situation.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
