Abstract
The utility model relates to a bearing box, in particular to an upward push type crusher bearing box structure which comprises a bearing cover and a bearing block. The bearing block is fixedly connected with a machine frame, the bearing box is provided with a bearing cover with the bearing center serving as an interface, a connecting pin is arranged on the vertical contact area of the end of the bearing cover and the bearing block, the bearing cover and the bearing block are respectively provided with a half pin hole, the half pin hole in the bearing cover and the half pin hole in the bearing block are in butt joint to form a pin hole, and the connecting pin penetrates the pin hole to fix the bearing cover with the bearing block. The bearing box is provided with the bearing cover with the bearing center serving as the interface, the bearing block is connected with the whole bearing cover through a high-strength connecting bolt, a connecting pin at the seam allowance position of the bearing block and the bearing cover, and the strength is improved through double connection. The upward push type crusher bearing box structure has the advantages that a processing process of the upward push type crusher bearing box is simplified, and a movable jaw assembly is convenient to maintain; the crusher movable jaw assembly can be dismantled by dismantling the connecting pin and loosening a connecting bolt, a whole crusher does not need dismantling, and the upward push type crusher bearing box structure is convenient to dismantle and low in maintenance cost.
Description
Technical field
The utility model relates to a kind of bearing box, particularly relates to a kind of upper pushing-type disintegrator bearing box structure.
Background technique
At present, the bearing box part of upper pushing-type disintegrator, is made up of solid bearing box and bearing support, and bearing support is welded in frame, and bearing support connects by six attachment pegs with solid bearing box.In production process, solid bearing box and bearing support are joined brill, align reaming, and processing technology is loaded down with trivial details.And disintegrator is through using, very large shearing stress is born in two cross sections of attachment pegs, the of long duration faulting of slab ends phenomenon that just occurs.If disintegrator bearing goes wrong in using process, user cannot lay down attachment pegs at the scene, near the repair location moving jaw assembly is transported to, and whole disintegrator must be transported to manufacturer's maintenance, bring inconvenience to user's maintenance.
Summary of the invention
The utility model is intended to solve the problems referred to above that existing upper pushing-type disintegrator exists, and provide a kind of with high-strength bolt and stop portion add pin connection, production and upper pushing-type disintegrator bearing box structure easy to maintenance.
Realize above-mentioned purpose by the following technical solutions:
The technological scheme that the utility model solves described problem employing is:
Pushing-type disintegrator bearing box structure in one, comprise bearing cap and bearing support, bearing is placed in bearing box, bearing support is fixed in frame, described bearing box arranges bearing cap take bearing centre as separating surface, and the end of bearing cap is provided with attachment pegs with the vertical surface of contact of bearing support, respectively establishes half pin-and-hole on bearing cap and bearing support, the composition pin-and-hole that connects of half pin-and-hole on bearing cap and bearing support, attachment pegs from pin-and-hole through bearing cap and bearing support are fixed.
Further, described bearing cap and bearing support seam location, stop portion connects with pin, and bearing cap is connected with bolt with bearing support entirety.
Further, described bearing cap connects with bearing support with four high-strength bolts.
Further, four described high-strength bolt specifications are identical corresponding between two.
Adopt technique scheme, compared with existing upper pushing-type disintegrator bearing box, bearing box of the present utility model arranges bearing cap take bearing centre as separating surface, bearing support is connected with high strength connecting bolt with the entirety of bearing cap, and add connecting pin connection at both stop portions, dual connection reinforcement intensity, its beneficial effect is: the processing technology of having simplified upper pushing-type disintegrator bearing box, make the easy to maintenance of jaw assembly, draw off attachment pegs, unclamp attachment bolt, just can take moving jaw assembly apart, rather than whole disintegrator, convenient disassembly, maintenance cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
In figure, bearing support 1, connecting pin 2, connecting bolt 3, bearing cap 4.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
The present embodiment is a kind of upper pushing-type disintegrator bearing box structure, and this structure is by bearing support 1, connecting pin 2, and connecting bolt 3, bearing cap 4 forms.Its design philosophy is: bearing support 1 is connected with high strength connecting bolt 3 with the entirety of bearing cap 4, and adds connecting pin 2 at both stop portions and connect, and dual connection reinforcement intensity is convenient to dismounting.
Concrete structure is shown in Fig. 1, Fig. 2, bearing is placed in bearing box, bearing box arranges bearing cap 4 take bearing centre as separating surface, after bearing support 1 roughing, be welded in frame, bearing cap 4 connects with bearing support 1 use high strength connecting bolt 3, connecting bolt 3 arranges four, and four high-strength bolt specifications are identical corresponding between two.
Bearing cap 4 and bearing support 1 seam location, for reducing the stressed of connecting bolt 3, stop portion connects by attachment pegs 2, namely be provided with attachment pegs 2 in the end of bearing cap 4 and the vertical surface of contact of bearing support 1, on bearing cap 4 and bearing support 1, respectively establish pin-and-hole half, bearing cap 4 and half pin-and-hole on the bearing support 1 composition pin-and-hole that connects, attachment pegs 2 from pin-and-hole through bearing cap 4 is fixing with bearing support 1.Bear part crushing force by attachment pegs 2.In the whole length of attachment pegs 2, all stressed, rather than a cross section is stressed, attachment pegs there will not be faulting of slab ends phenomenon, is convenient to drawing off of pin when dismounting.
Claims (4)
1. a upper pushing-type disintegrator bearing box structure, comprise bearing cap and bearing support, bearing is placed in bearing box, bearing support is fixed in frame, it is characterized in that, described bearing box arranges bearing cap take bearing centre as separating surface, the end of bearing cap is provided with attachment pegs with the vertical surface of contact of bearing support, on bearing cap and bearing support, respectively establish half pin-and-hole, the composition pin-and-hole that connects of half pin-and-hole on bearing cap and bearing support, attachment pegs from pin-and-hole through bearing cap and bearing support are fixed.
