Abstract
The invention relates to a disassembly and assembly tool for a support sleeve, which is used in the maintenance process of a balance shaft bearing. The disassembly and assembly tool comprises a portal bracket and is characterized in that the portal bracket is composed of two supporting columns and a cross beam used for connecting the two supporting columns; the cross beam is a square steel crossing over the diameter of the supporting sleeve; a vertically-through center hole is formed in the middle of the cross beam; a nut is arranged at the upper part of the center hole in the cross beam; a pull rod penetrating through the center hole and provided with an external thread is connected with the interior of the nut; a rotary arm driving the pull rod to rotate is arranged at the upper end of the pull rod; at least three openable and closeable claws are arranged at the lower part of the pull rod and in the same plane through connecting pieces. The disassembly and assembly tool for the support sleeve has the benefits as follows: when the tool is used, both time and labor are saved and the support sleeve can be dissembled and assembled safely.
Description
Technical field
The present invention relates to a kind of support set and decompose combination tool, be applied in the maintenance process of balance shaft bearing.
Background technology
Because Long-Time Service in the presence of a harsh environment, the needle bearing outer ring in trunnion shaft axle sleeve and oil baffle can produce corrosion and combine closely with trunnion shaft axle sleeve.Being oil baffle outside needle bearing outer ring, needle bearing outer ring should being changed when protecting oil baffle when peacetime repair.Do not have ready-made instrument dismantling device at present, the violence methods such as general conventional hammering are disassembled, and not only waste time and energy and also often cause the damage of oil baffle.
Summary of the invention
In order to make up the deficiencies in the prior art, the invention provides a kind ofly to save time, laborsaving and the support set extracting and install support set of safety decomposes combination tool.
The present invention is achieved through the following technical solutions:
A kind of support set decomposes combination tool, comprise gantry support, it is characterized in that: described gantry support is made up of with the crossbeam being connected two pillars two pillars, described crossbeam is the square steel across support set diameter, the middle part of crossbeam is provided with centre bore penetrating up and down, centre bore top on crossbeam arranges a nut, the externally threaded pull bar of band that one passes centre bore is connected in described nut, the upper end of described pull bar is provided with the pivoted arm driving pull bar to rotate, and described pull bar bottom evenly arranges at least three by connector at same plane can the hook of folding.
For ease of making, described pull bar and pivoted arm design for split-type structural, and the upper end of pull bar and one end of pivoted arm are provided with the face of matching; The top of described pull bar is hexa-prism structure, and one end of pivoted arm is provided with the hole corresponding with hexa-prism structure.
For ease of regulating the folding of hook, strengthen the support force of hook, the bottom of described pull bar is inversed taper platform structure, and the rear end of described hook is close on the conical surface of inversed taper platform structure.
In order to ensure that nut and outer threaded pull bar have stronger non-deformability, pull bar can adopt leading screw to make, and described nut and outer threaded pull bar all adopt structural alloy steel 35CrMo make and do modifier treatment, and described screw thread is saw-tooth thread.
In order to ensure that effect grabbed by hook, extend the service life of this equipment, described hook is the L-type structure that made by structural alloy steel 35CrMo and does modifier treatment.
For reducing cost of manufacture, the upper end outer surface of described pull bar is six rod structures of standard specification.
For reducing friction, also arrange gasket ring between described nut and crossbeam, described gasket ring is thrust bearing.
The inside of described connector is provided with the internal thread corresponding with pull bar, and the outside of connector is provided with the boss for being connected with hook.
Support set of the present invention decomposes combination tool beneficial effect: when using the present invention to dismantle support set, only first need reconcile hook makes it withstand the inwall of support set, then pivoted arm is rotated, pull bar drives hook to rise along screw thread, thus drive support set to move out or move, therefore this equipment save time, laborsaving, can safety dismounting support set.
