Abstract
The utility model discloses a device for assembling a bearing pedestal, which comprises a pressure disc and a positioning pin. A plurality of pin passing holes are arranged at the edge side of the pressure disc. The pin passing holes are matched with a through hole in the bearing pedestal and a threaded hole of a flywheel in a contraposition manner; and one end of the positioning pin with threads is screwed into the threaded hole of the flywheel through the pin passing holes of the pressure disc and the through hole in the bearing pedestal. The device also comprises a supporting seat and a screw rod. The supporting seat is tightly attached to the flywheel, and the center of the supporting seat is a bolt hole; the screw rod is connected with the bolt hole through threads and penetrates through the bolt hole, and one end of the screw rod is propped against the pressure disc. The utility model can effectively ensure the requirements of assembly quality and has the advantages of low cost. Through the high-precision positioning guide of the positioning pin, the assembly coaxiality can be effectively ensured and the centering effect is good.
Description
Technical field
The utility model relates to a kind of auxiliary assembling device, relates in particular to a kind of device of assembled shaft bearing.
Background technology
In engine manufacturing field,,, need the problem that solves centering (coaxial) and be seated in the practical set because the bearing block size is bigger because of bearing block and flywheel are interference fits.At present, the device of bearing block (with the bearing assembling one) flywheel of packing into is had following two kinds: first kind simple in structure, but need with manually directly beaing, and wastes time and energy and be difficult to guarantee assembling quality requirement; Second kind of employing hydraulic means, complex structure though can effectively assemble, have high input, the cost height.
Summary of the invention
This reality has novel purpose to be to provide a kind of device that can easy reliable assembled shaft bearing, and this device can effectively guarantee assembling quality requirement and have the little advantage of cost.
This reality has the novel device that a kind of assembled shaft bearing is provided, this device comprises: platen and alignment pin, the edge side of described platen is provided with several and crosses pin-and-hole, describedly cross pin-and-hole and the through hole of bearing block and the threaded hole of flywheel contraposition is adaptive mutually, the end that described alignment pin has screw thread screws in the screwed hole of described flywheel by the mistake pin-and-hole of this platen and the through hole on the described bearing block.
Wherein, this device also comprises supporting seat and screw rod, and described supporting seat is adjacent to flywheel, and its center is a screw; Described screw rod is threaded with described screw, and passes described screw, and an end of described screw rod and described platen be apical grafting mutually.
The device of this assembled shaft bearing can effectively guarantee the axiality (centering is effective) of assembling by the hi-Fix guiding of alignment pin.
Description of drawings
Profile when Fig. 1 is the assembling of this device.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
The 1-alignment pin, the 2-platen, the 3-supporting seat, the 4-screw rod, the 5-flywheel, 6-bearing block (bearing is packed into wherein), the 7-platen is crossed pin-and-hole, 8-bearing block through hole, 9-flywheel screwed hole, 10-transition face, 11-screw.
The specific embodiment
Further specify the device of the utility model assembled shaft bearing below in conjunction with accompanying drawing.
As shown in Figure 1, among the utility model embodiment, the device of this assembled shaft bearing comprises: platen 2 and alignment pin 1.Platen 2 is fitted with bearing block 6, and alignment pin 1 is crossed in pin-and-hole 7, the bearing block through hole 8 screw-in flywheel screwed holes 9 by platen, and bearing block 8 is fixed in the flywheel shaft bearing hole.Alignment pin 1 is by crossing the accurate location of little matched in clearance of pin-and-hole 7 with platen and leading.By the hi-Fix guiding of alignment pin 1, effectively guarantee the axiality (centering is effective) of assembling.
In the present embodiment, described platen is a disc structure, crosses pin-and-hole for four and is evenly distributed on around the platen, and platen comprises that also four are removed repeated hole, and the one side that platen contacts with bearing block has the pit of dodging.
The device of this assembled shaft bearing also comprises: supporting seat 3 and screw rod 4.This supporting seat 3 is adjacent to flywheel 5, and the center is a screw 11; These screw rod 4 shafts are the thread structure that cooperates with this supporting seat screw 11, and behind screw rod 4 screw-in screws 11, the one end is pushed down platen 2, makes platen 2 impeller-hub bearings 6 enter flywheel shaft bearing hole.
In the present embodiment, the power of air pressure gun connects just and bearing block can be seated by the biography of supporting seat, platen, and is time saving and energy saving and effectively guarantee assembling quality requirement.
The device of the utility model assembled shaft bearing drops into little, easy and simple to handle (only needing an air pressure gun during use), and can effectively guarantee assembling quality requirement.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
