Abstract

A kind of spindle nose formula bearing block, design one endoporus of processing is for installing first bearing (3) at the second axis (2) spindle nose in cylinder gear speed reducer as shown in Figure 1 or 2, the outer ring of its first bearing (3) matches with endoporus at the second axis (2) spindle nose, and the inner ring of first bearing (3) matches with the shaft end axle journal of first axle (1).It is used to assemble second bearing (4) and 3rd bearing (5) in evagination cylinder lumen design one through-hole of processing of two kinds of reduction cases (6), the corresponding axle journal of the inner ring and the second axis (2) of second bearing (4) and 3rd bearing (5) matches.

Description

Spindle nose formula bearing block

(1), technical field：The present invention is to manufacture and design a kind of spindle nose formula bearing block, is not easy to pacify in transmission case for substituting Dress or the bearing block that can not be installed.

(2), background technology：General bearing block has a plain bearing housing and rolling bearing pedestal at present, and plain bearing housing has pair Open type and monoblock type, rolling bearing pedestal has that two studs are vertical and four studs are vertical.

Three, invention content：The present invention is that a kind of spindle nose formula bearing block of design and manufacture is used to be mounted on two level as shown in Figure 1 On cylinder gear speed reducer or three-level cylinder gear speed reducer as shown in Figure 2.It is characterized in that：In two level as shown in Figure 1 At the second axis (2) spindle nose in cylinder gear speed reducer or three-level cylinder gear speed reducer as shown in Figure 2 in design processing one Hole matches for assembling first bearing (3), outer ring and the endoporus at the second axis (2) spindle nose of first bearing (3), first bearing (3) inner ring and the shaft end axle journal of first axle (1) match；In the outer of Two Grade Column Gear Reducer babinet (6) as shown in Figure 1 The evagination cylinder lumen of convex cylinder lumen or three-level cylinder gear speed reducer babinet (6) as shown in Figure 2, design one through-hole of processing For assembling second bearing (4) and 3rd bearing (5), the outer ring and reduction case of second bearing (4) and 3rd bearing (5) (6) through-hole of evagination cylinder matches, the inner ring axle journal phase corresponding to the second axis (2) of second bearing (4) and 3rd bearing (5) Match.

(4) it illustrates：Fig. 1 and Fig. 2 is respectively two level and three-level cylinder gear speed reducer structure diagram.

1, first axle 2, the second axis 3, first bearing 4, second bearing 5,3rd bearing 6, babinet

(5) specific implementation mode：As shown in Figure 1 or 2, it is processed with first bearing on the spindle nose of the second axis (2) (3) endoporus of outer ring matches for installing first bearing (3), the inner ring of first bearing (3) with the shaft end axle journal of first axle (1). The endoporus of the outer ring with second bearing (4) and the outer ring of 3rd bearing (5) is processed on the evagination cylinder inboard wall of babinet (6), For installing second bearing (4) and 3rd bearing (5), the inner ring of second bearing (4) and the inner ring and the second axis of 3rd bearing (5) (2) corresponding axle journal matches.Second bearing (4) should be set at a distance from larger with 3rd bearing (5).By answering for both the above retarder After general bearing block between first axle (1) and the second axis (2) spindle nose is changed to spindle nose formula bearing block, this two kinds can be made to subtract Fast device structure is more compact, and volume smaller, weight are lighter, and manufacturing cost is lower, and when the gear in retarder is bigger, babinet also can Bigger, using spindle nose formula bearing block, its superiority is more apparent, but the second axis (2) should be designed the rigidity and stabilization that have larger Property.

Claims

1. a kind of spindle nose formula bearing block, in Two Grade Column Gear Reducer as shown in Figure 1 or three-level Cylinder Gear as shown in Figure 2 One endoporus of design processing is used to assemble first bearing (3) at the second axis (2) spindle nose in wheel decelerator, first bearing (3) Outer ring matches with endoporus at the second axis (2) spindle nose, and the inner ring of first bearing (3) matches with the shaft end axle journal of first axle (1)；Such as The evagination cylinder lumen of Two Grade Column Gear Reducer babinet (6) shown in FIG. 1 or three-level roller gear as shown in Figure 2 slow down The evagination cylinder lumen of device babinet (6), design one through-hole of processing is for assembling second bearing (4) and 3rd bearing (5), and second The through-hole of the evagination cylinder of the outer ring of bearing (4) and 3rd bearing (5) and reduction case (6) matches, second bearing (4) and the The inner ring of three bearings (5) matches to the corresponding axle journal of the second axis (2).
