Abstract
The invention relates to bearing mounting equipment. The bearing mounting equipment is characterized in that a hydraulic system is arranged on one side of a base, one end of a piston of the hydraulic system is fixedly connected with a fixed baffle, a hydraulic oil pump is arranged on the other side of the base and fixedly connected with a hydraulic oil cylinder through an oil pipe, the hydraulic oil cylinder is positioned between the hydraulic oil pump and the fixed baffle, and a valve is arranged on the hydraulic oil pump. One end of a piston of the hydraulic oil cylinder is fixedly connected with a second pressure plate, two first pressure plates are arranged between the second pressure plate and the fixed baffle and positioned on two axial sides of the hydraulic oil cylinder respectively, and the first pressure plates are fixedly connected with air cylinders respectively. The bearing mounting equipment has the advantages of simple structure, convenience in operation and maintenance, allowance of mounting of large-size bearings, relief of labor intensity, alleviation of damage conditions of the bearings, accuracy in installation, realization of automatic installation and improvement of production efficiency.
Description
Technical field
The present invention relates to a kind of bearing erection unit.
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
For problems of the prior art, the object of the present invention is to provide a kind of technical scheme of bearing erection unit.
Described a kind of bearing erection unit, it is characterized in that comprising 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.
Described a kind of bearing erection unit, is characterized in that described valve is overflow valve.
Described a kind of bearing erection unit, is characterized in that 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: 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the left view at A place;
In figure: 1-hydraulic system, 2-fixed dam, 3-cylinder, 4-first pressing plate, 5-second pressing plate, 6-hydraulic jack, 7-hydraulic oil pump, 8-valve, 9-base, 10-bearing, 11-bearing block, 12-oil pipe.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention will be further described:
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, and the outer end of the piston rod of 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.
