Abstract
The utility model relates to a flywheel supporting sleeve of pressing machines, which mainly solves the problems that the loading and the dimension of a flywheel shaft are big, and the designing cost is high. The flywheel supporting sleeve is characterized in that a flywheel supporting sleeve (5) is connected between a flywheel (1) and a flywheel shaft (4) through a combined bearing (2), the cavity of the flywheel supporting sleeve (5) is in an electric torch shape which is transversely arranged, the periphery of a middle transition section (11) of the electric torch shape is provided with a flange plate (8) which is connected with a lathe bed (3), the end surfaces of cylindrical sections (10, 12) of the left and the right ends of the electric torch shape are respectively provided with bearings (6) and bearing end covers (9), the flywheel supporting sleeve (5) is connected with the flywheel shaft (4) through the bearings (6) and the bearing end covers (9), and the cylindrical section (12) is combined with the flywheel (1) through the combined bearing (2). The flywheel supporting sleeve of pressing machines improves the bearing state of the flywheel shaft, reduces the structure dimension of the flywheel shaft, then reduces the structure dimension of a whole driving system, reduces the loading of the flywheel shaft, and reduces the designing cost.
Description
Technical field:
The utility model relates to a kind of forging equipment, is specifically related to be installed in the pressure flywheel splicing sleeve on the forcing press.
Background technology:
Forcing press work characteristics in the forging equipment is the peak load of short time, and uses motor can not satisfy the rapid variation of load separately.Pressure flywheel plays the effect of storing and releasing energy in press structure, adopt the flywheel rear flywheel to get up the energy storage that motor is constantly supplied with, and during forcing press work, flywheel is by reducing the energy that rotating speed output is stored.The big more size of flywheel that requires of forcing press institute energy requirement is also big more, but because of flywheel directly combines with flywheel shaft by combination bearing, flywheel shaft promptly will bear the caused bending load of weight that operation torque bears rotating parts such as flywheel again, during design in order to satisfy the strength and stiffness requirement of flywheel shaft, the flywheel shaft size will strengthen a lot, cause the size of whole running part to increase, increased design cost.
The utility model content:
Technical problem to be solved in the utility model is at the problem that exists in the background technology, and a kind of pressure flywheel splicing sleeve is provided, and this pressure flywheel splicing sleeve can effectively reduce the load and the size of flywheel shaft, reduces design cost.
The invention for solving the technical problem can reach by following technical solution: this pressure flywheel splicing sleeve comprises flywheel, combination bearing, lathe bed, flywheel shaft, be connected the flywheel splicing sleeve by combination bearing between flywheel and the flywheel shaft, described flywheel splicing sleeve cavity is horizontal torch tubular, its middle part changeover portion is with outward and lathe bed flange connecting dish, the cylindrical section end of its left and right end is adorned bearing and bearing (ball) cover respectively, the flywheel splicing sleeve is connected with flywheel shaft by bearing, bearing (ball) cover, and its right-hand member cylindrical section combines with flywheel by combination bearing.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: this pressure flywheel splicing sleeve is owing to adopt said structure, improved the force-bearing situation of flywheel shaft, thereby dwindled the physical dimension of flywheel shaft, so that dwindled the physical dimension of whole drive system, alleviate the load of flywheel shaft, reduced design cost.This structural safety reliability height has excellent popularization and is worth.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is structural representations of flywheel splicing sleeve 5 of the present utility model;
Accompanying drawing 3 is left views of accompanying drawing 2.
Among the figure: 1-flywheel, 2-combination bearing, 3-lathe bed, 4-flywheel shaft, 5-flywheel splicing sleeve, 6-bearing, 7-bolt, 8-ring flange, 9-bearing (ball) cover, 10-cylindrical section, 11-changeover portion, 12-cylindrical section.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
Fig. 1 is in conjunction with shown in Figure 2, and this pressure flywheel splicing sleeve comprises flywheel 1, combination bearing 2, and lathe bed 3 is connected flywheel splicing sleeve 5 by combination bearing 2 between the flywheel shaft 4, flywheel 1 and flywheel shaft 4, and flywheel shaft 4 is equipped with in flywheel splicing sleeve 5 inside.As Fig. 2, shown in Figure 3, flywheel splicing sleeve 5 cavitys are horizontal conventional torch tubular, its middle part changeover portion 11 outer being with and lathe bed 3 flange connecting dishes 8, be that flywheel splicing sleeve 5 connects lathe bed 3 by the bolt hole on the ring flange 8 by bolt 7, cylindrical section 12 ends of the cylindrical section 10 of its left end, right-hand member are adorned bearing 6 and bearing (ball) cover 9 respectively, flywheel splicing sleeve 5 is connected with flywheel shaft 4 by bearing 6, bearing (ball) cover 9, and cylindrical section 12 combines with flywheel 1 by combination bearing 2.Combination bearing 2 is a single-row radial ball bearing, can bear bigger radial load; After flywheel splicing sleeve 5 was combined into one with pressure fuselage rigidity, flywheel shaft 4 did not bear the power that flywheel splicing sleeve 5 transmits, and the weight of flywheel 1 rotating part such as grade acts directly on the lathe bed 3 by flywheel splicing sleeve 5, and 4 of flywheel shafts bear operation torque.Therefore, thereby the utility model structure has been improved the physical dimension that the force-bearing situation of flywheel shaft has dwindled flywheel shaft greatly, so that has dwindled the physical dimension of whole drive system, has reduced design cost.This structural safety reliability height has excellent popularization and is worth.
