Description
Technical field
The present invention relates to a kind of bearing erection unit, especially relate to a kind of device that can be quickly installed to by large scale bearing fast in bearing block.
Background technology
Bearing outer ring and bearing saddle bore tight fit, when inner ring and axle are comparatively loose fit, be generally first pressed into bearing in bearing saddle bore.The quality that bearing is installed whether, will have influence on the precision of bearing, life-span and performance.In the installation process of bearing, should carry out in totally dustless space as far as possible.Bearing three kinds of methods are installed: cold setting is legal, hot charging matching method and hydraulic pressure assembling method.
When using prior art that bearing is installed, symmetrical shock bearing in installation process, and in knockout process, stress point is not easy to grasp, hit with a hammer owing to adopting, impulsive force is large, easily cause the damage of bearing, also easily make shaft strength uneven, cause that bearing is crooked cannot push ahead, the installation of the bearing that size is large is wasted time and energy, and easily damages bearing in installation process.Therefore, need badly one is proposed can bearings mounted bearing Mounting device fast, accurately.
Summary of the invention
The present invention needs the problem solved to be to provide a kind of bearing erection unit, device structure advantages of simple, can the larger bearing of installation dimension, and installation accuracy is high, reduces labour intensity.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of bearing erection unit, comprise hydraulic system, fixed dam, cylinder, first pressing plate, second pressing plate, hydraulic jack, hydraulic oil pump, valve, base and oil pipe, described base side is provided with hydraulic system, one end of the piston of described hydraulic system is fixedly connected with fixed dam, described base opposite side is provided with hydraulic oil pump, described hydraulic oil pump is fixedly connected with hydraulic jack by oil pipe, described hydraulic jack is placed between hydraulic oil pump and fixed dam, described hydraulic oil pump is provided with valve, one end of the piston of described hydraulic jack is fixedly connected with the second pressing plate, the first pressing plate is provided with between described second pressing plate and fixed dam, first pressing plate has two and is placed in the both sides of hydraulic jack axial direction respectively, first pressing plate is fixedly connected with cylinder respectively.
Further, described valve is overflow valve.
Further, the outer end of the piston rod of described hydraulic jack is removably connected with installation sleeve.
The advantage that the present invention has and good effect are: this device structure is simple, and convenient operation and maintenance, can install large-sized bearing, reduce labour intensity, reduce the damaged condition of bearing, and install accurately, equipment realizes Auto-mounting, improves production efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.
As shown in Figure 1, the invention provides a kind of bearing erection unit, comprise hydraulic system 1, fixed dam 2, cylinder 3, first pressing plate 4, second pressing plate 5, hydraulic jack 6, hydraulic oil pump 7, valve 8, base 9 and oil pipe 12, described base 9 side is provided with hydraulic system 1, one end of the piston of described hydraulic system 1 is fixedly connected with fixed dam 2, described base 9 opposite side is provided with hydraulic oil pump 7, described hydraulic oil pump 7 is fixedly connected with hydraulic jack 6 by oil pipe 12, described hydraulic jack 6 is placed between hydraulic oil pump 7 and fixed dam 2, described hydraulic oil pump 7 is provided with valve 8, one end of the piston of described hydraulic jack 6 is fixedly connected with the second pressing plate 5, the first pressing plate 4 is provided with between described second pressing plate 5 and fixed dam 2, first pressing plate 4 has two and is placed in the both sides of hydraulic jack 6 axial direction respectively, first pressing plate 4 is fixedly connected with cylinder 3 respectively.
Described valve 8 is overflow valve.
The outer end of the piston rod of described hydraulic jack 6 is removably connected with installation sleeve.
The course of work of this example: when implementing of the present invention, bearing block 11 is placed on below the first pressing plate 4, the stiff end at bearing block 11 two ends is placed on below the first pressing plate 4, cylinder 3 drives the first pressing plate 4 to press down and is fixed bearing block 11 position, the piston of hydraulic system 1 stretches out and drives fixed dam 2 and bearing block 11 1 side contacts, bearing 10 one end is first pressed in bearing block 11 hole, then hydraulic oil pump 7 starts, fuel feeding is to hydraulic jack 6, hydraulic jack 6 driven plunger is stretched out and is driven second baffle 5 to move forward, apply pressure to the other end of bearing 10, slowly bearing 10 is pressed in bearing block 11 hole, valve 8 is overflow valve, the installing force varying in size required of bearing 10 is different, therefore valve 8 is adjustable, the fuel delivery of regulator solution pressure oil pump 7, the size of adjustment installing force.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
