As shown in Figure 4, fixture 40 includes being positioned at below rotary shaft 21 and the clamping slide rail 41 vertical with rotary shaft 21, clamping
Slide rail 41 best level is arranged, and it has T-shaped chute 42, slidably connects two movable sliders (figure in T-shaped chute 42
Not shown in), each slide block is respectively fixedly connected with clamping bolt 43 that is vertical with clamping slide rail 41 and that vertically arrange, i.e. clamping
Bolt 43 has two, and one end of clamping bolt 43 passes from T-shaped chute 42, and on clamping bolt 43, spiral connection has clamping
Nut 44, clamping nut 44 is preferably also provided with the handle identical with locking nut 99, naturally it is also possible to use plain nut to make
For clamping nut 44.
When using above-mentioned fixture 40, need to be located in vertical shaft bearing 11 tested bearing holder (housing, cover), two clamping bolts 43
It is respectively interposed on the bolt hole of vertical shaft bearing 11 both sides, and is locked on clamping slide rail 41 by clamping nut 44.
The structure of above-mentioned fixture 40 be only capable of with vertical shaft bearing 11 with the use of, also can flange bearing in order to ensure fixture 40
Seat with the use of, it is preferred that as it is shown in figure 5, in the present embodiment, fixture 40 also includes that two can be slided on clamping slide rail 41
Clamping block 45, two clamping blocks 45 lay respectively at the both sides of rotary shaft 21, clamping block 45 offers clamping groove 46 and with dress
The perforation 47 that folder bolt 43 coordinates, the length direction of clamping groove 46 is the most vertical with rotary shaft 21 and clamping slide rail 41, i.e. clamping
The length direction of groove 46 is vertical direction.During use, two clamping blocks 45 are adjusted to and the bolt of flange shaft bearing 12 both sides
On the position that hole is corresponding, clamping nut 44 is interspersed in the perforation 47 of correspondence simultaneously and locks with clamping nut 44, then will
The both sides of flange shaft bearing are locked on the clamping groove 46 of correspondence.Flange shaft bearing 12 is except can be as shown in Figure 5
Outside circular flange bearing block, it is also possible to be square flange bearing block as shown in Figure 6, or rhombus flange as shown in Figure 7
Bearing block.
Further, as shown in Figure 8, in the present embodiment, clamping block 45 offers the most vertical towards the side of rotary shaft 21
The first V-shaped groove 48 and the second V-shaped groove 49 that be straight and that be interconnected, for ease of clamping the machining of block 4, the first V-shaped groove 48 and the
Two V-shaped grooves 49 all offer for the slot to make way for machine tool of stepping down.In addition the length direction of the first V-shaped groove 48 with turn
Moving axis 21 the most identical.So when tested bearing 13 is not installed at directly testing on bearing block, can be by two
Tested bearing 13 is clamped by clamping block 45, and the first V-shaped groove 48 and the second V-shaped groove 49 on clamping block 45 can effectively limit bearing
Axially or radially rock, preferably clamp tested bearing 13, it is ensured that test data are accurate.
As it is shown in figure 9, load maintainer 30 includes lever 31, adjusting part 32, connects assembly 33 and be fixed on frame 10
On the first support 34 and the second support 35, the first support 34 and the second support 35 lay respectively at the both sides of rotary shaft 21, wherein
First support 34 is gantry frame structure, and one end of adjusting part 32 is rotatably connected on the cross bar at the first support 34 top, another
Holding the one end with lever 31 to be rotationally connected, the other end of lever 31 is rotatably connected on the second support 35, connects the one of assembly 33
End is rotatably connected on the shaft of lever 31, and the other end is rotatably connected on clamping slide rail 41, and the second adjusting part 33 is positioned at
The underface of rotary shaft 21.So, with position that lever 31 and the second support 35 are rotationally connected as fulcrum, by changing regulation group
The swing of the length control lever 31 of part 32, lever 31 pulls fixture 40 by connecting assembly 33, tested bearing is loaded pressure
Power, anti-when receiving radial pressure with the anti-wear performance of this test bearing and bearing spatters performance.
Adjusting part 32 include upper bolt 32c that long nut 32a, compression spring 32b and the first support 34 be rotationally connected with
And the lower bolt 32d being rotationally connected with lever 31, the thread rotary orientation of upper bolt 32c and lower bolt 32d is contrary, long nut 32a's
Two ends connect with upper bolt 32c and lower bolt 32d spiral respectively, so by rotating long nut 32a, i.e. adjustable adjusting part
The length of 32, compared with the technical scheme of conventionally employed oil cylinder, structure is simpler, and advantage of lower cost.
Go back spiral connection on upper bolt 32c and have stop nut 32e, the thread rotary orientation phase of stop nut 32e and long nut 32a
Instead, use stop nut 32e and long nut 32a can form double nuts structure, make screw thread pair produces not with external applied load change
Additonal pressure, and always there are moment of friction, effectively prevent long nut 32a from rotating relative to upper bolt 32c, it is ensured that tested bearing
The test pressure stability being subject to.
On lower bolt 32d, spiral connects holding nut 32f, and compression spring 32b is set on lower bolt 32d, and compression
One end of spring 32b is supported on holding nut 32f, and the other end is supported on long nut 32a.
Connect assembly 33 and include the lower company that the upper connecting rod 33a being rotationally connected with clamping slide rail 41 is rotationally connected with lever 31
Bar 33b and for connecting the securing member 33c of connecting rod 33a and lower link 33b, it is of course also possible to use two ends respectively with dress
The connecting rod that folder slide rail 41 and lever 31 are rotationally connected replaces above-mentioned connection assembly 33.
Above in conjunction with accompanying drawing, this utility model is described in detail, but embodiment of the present utility model not only
Being limited to above-mentioned embodiment, this utility model can be made various deformation according to prior art by those skilled in the art, as incited somebody to action
