Abstract
The utility model provides an adjusting structure of a mainshaft bearing, which comprises a main shaft, a bearing, a backing ring and a ring flange, wherein the inner end of the main shaft is arranged inside a box body, the bearing is arranged on the main shaft, the backing ring is arranged between the bearing and the rear end face of the main shaft, the ring flange connected with the lateral end of the box body is arranged at the outer side of the backing ring, a step of the ring flange is pressed on the backing ring; two semi-circular ring spacers spliced to a circular ring are arranged between the backing ring and the bearing, and the distance between the rear end face of the main shaft and the backing ring is greater than the width of the semi-circular spacer. When the bearing needs to be adjusted, the ring flange is loosened, and the backing ring is moved toward the rear end of the main shaft. Because the distance between the rear end face of the main shaft and the backing ring is greater than the width of the semi-circular spacer, the semi-circular ring spacers can be conveniently dismounted to be processed in a match grinding way. The adjusting structure of a mainshaft bearing adopts two semi-circular spacers, thereby having reasonable structure, being convenient to assemble and disassemble as well as process, having high processing accuracy, keeping the prior strength of the main shaft and being particularly suitable for the bearing adjustment of a rigid main shaft.
Description
Technical field
The utility model belongs to the universal machine technical field, specifically a kind of adjustment structure of main shaft bearing.
Background technique
At present, the adjustment structure of existing main shaft bearing mainly contains following two kinds of forms: a kind of is that three equally distributed adjustment screws are installed on the end face of main shaft, realize the adjusting of bearing by regulate adjusting screw, though this adjustments structure simple, be easy to adjusting, can reduce the rigidity of main shaft; Another kind is between rear-end of spindle face and bearing spacer to be set, adjust bearing by the width of regulating spacer,, need when changing spacer to carry out from the other end of main shaft owing to be subjected to the restriction of spindle nose step, parts on the main shaft all must be dismantled, it is very inconvenient to adjust.
The model utility content
Technical problem to be solved in the utility model is, at the deficiencies in the prior art, provide a kind of rational in infrastructure, be easy to process, the adjustment structure of machining accuracy height, the main shaft bearing being convenient to operate.
The technological scheme that its technical problem that solves the utility model adopts is: comprise main shaft, bearing, gasket ring and flange plate, the inner of main shaft places in the casing, bearing is loaded on the main shaft, between bearing and rear-end of spindle face, be provided with gasket ring, in the outside of gasket ring the flange plate that links to each other with the casing side is housed, the step of flange plate is pressed on the gasket ring; It is characterized in that: between gasket ring and bearing, be provided with the spacer that is combined into by two semicircular ring spacers, and the distance between rear-end of spindle face and the gasket ring is greater than the width of semicircle spacer.When needs are adjusted bearing, unclamp flange plate, gasket ring is moved to the rear-end of spindle face, because the distance between rear-end of spindle face and the gasket ring greater than the width of semicircular ring spacer, is carried out match grinding processing so can unload the lower semi-circle spacer easily.
The beneficial effects of the utility model are: owing to adopt two semicircular ring spacers, thereby it is rational in infrastructure, and easy accessibility, and be easy to processing, machining accuracy height, kept the original intensity of main shaft, be specially adapted to the bearing adjustment of rigidity main shaft.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 is that bearing, 2 is that semicircular ring spacer, 3 is that gasket ring, 4 is that flange plate, 5 is that water bar, 6 is that main shaft, 6-1 are that rear-end of spindle face, 7 is a casing.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
The utility model mainly is made up of main shaft 6, bearing 1, gasket ring 3 and flange plate 4, the inner of main shaft 6 places in the casing 7, bearing 1 is loaded on the main shaft 6, between bearing 1 and rear-end of spindle face 6-1, be provided with gasket ring 3, the flange plate 4 that links to each other with casing 7 outboard ends is housed in the outside of gasket ring 3, the step of flange plate 4 is pressed on the gasket ring 3, and water bar 5 is housed on the exterior edge face of flange plate 4; Between gasket ring 3 and bearing 1, be provided with the complete annulus that is combined into by 2, two semicircular ring spacers 2 of two semicircular ring spacers, and between rear-end of spindle face 6-1 and the gasket ring 3 apart from the width L of B greater than the semicircular ring spacer.
When needs are adjusted bearing 1, pull down water bar 5, unclamp flange plate 4, gasket ring 3 is moved to rear-end of spindle face 6-1, since between rear-end of spindle face 6-1 and the gasket ring apart from the width L of B, so easily just can unload semicircular ring spacer 2 greater than the semicircular ring spacer.The width L of semicircular ring spacer 2 is bigger, then carries out grinding; The width L of semicircular ring spacer 2 is less, then reconfigures.
When needing to adjust main shaft bearing, pull down water bar (5), unclamp flange plate (4), gasket ring (3) is moved backward, because the distance between rear-end of spindle face (7) and the gasket ring (3) greater than the width of semicircle spacer, is carried out match grinding processing so easily just can unload lower semi-circle spacer (3).
Claims (1)
1, a kind of adjustment structure of main shaft bearing, comprise main shaft, bearing, gasket ring and flange plate, the inner of main shaft places in the casing, bearing is loaded on the main shaft, between bearing and rear-end of spindle face, be provided with gasket ring, in the outside of gasket ring the flange plate that links to each other with the casing side is housed, the step of flange plate is pressed on the gasket ring; It is characterized in that: between gasket ring and bearing, be provided with the spacer that is combined into by two semicircular ring spacers, and the distance between rear-end of spindle face and the gasket ring is greater than the width of semicircle spacer.
