Description

Frock is used in synchronizer equipment

Technical Field

The utility model relates to the field of synchronizer machining equipment, in particular to a tool for assembling a synchronizer.

Background

A transmission is a mechanism for changing the speed and torque from an engine, which can change the ratio of the output shaft to the input shaft, either fixed or in steps, also known as a gearbox. The gear shifting of the old transmission adopts a 'two-foot clutch' mode, the upshifting needs to stay for a moment in a neutral position, and the downshifting needs to be performed by a refueling door in the neutral position so as to reduce the rotating speed difference of the gears. However, this operation is complicated and difficult to grasp accurately. Therefore, a synchronizer is used for ensuring that the gears to be meshed reach the same rotating speed, and the gears are firstly synchronized and then smoothly meshed.

The steel ball type synchronizer is widely used, and structurally comprises a gear hub, a gear sleeve, a spring, a steel ball and a synchronizer sliding block. Three groups of springs, steel balls and synchronizer sliders are installed in a gear hub of the synchronizer, and external teeth of the gear hub are meshed with internal teeth of a gear sleeve. During assembly of the synchronizer, tools such as a push rod and a screwdriver are usually adopted to press the steel balls in all directions into the sliding block hole one by one, so that the gear hub is pushed to drive the sliding block to enter the gear sleeve to complete assembly. However, the structure of the steel ball type synchronizer is complex, the steel ball, the small spring and the like are fine small parts, and if the steel ball is pushed to a position where the steel ball is contacted with and pressed by the spring, the steel ball is easy to be popped out by the spring due to incomplete pushing in the pushing process, so that the pushing of the steel ball into the sliding block is time-consuming and low in efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a tool for assembling a synchronizer, and the tool is used for solving the problem that a steel ball type synchronizer in the prior art is difficult to assemble.

In order to achieve the purpose, the utility model adopts the following technical scheme: a tool for assembling a synchronizer comprises a base, a limiting sleeve and a pressing ring; the base is vertically connected with a cylindrical mounting table in a sliding manner, and an elastic supporting piece is arranged between the base and the mounting table; the stop collar can be established in the outside of synchronous ware tooth hub, and the inside wall of stop collar is provided with the round spacing groove, is provided with the hole of placing that is used for placing the steel ball on the stop collar.

The principle and the advantages of the scheme are as follows: during practical application, among this technical scheme, adopt the bearing structure that base and mount table slip cap were established, under the initial condition, the mount table is the protrusion form and is located the top of base under elastic support piece's supporting role. When steel balls are assembled, a synchronizer to be assembled is arranged on the mounting table, the gear hub of the synchronizer is supported by the mounting table, the gear sleeve sleeved outside the gear hub moves downwards relative to the gear hub in the axial direction, the bottom of the gear sleeve is supported by the base, and the gear hub protrudes out of the gear sleeve. Then establish the stop collar cover in the outside of tooth hub, get the steel ball that treats the assembly in placing the hole to between pushing into stop collar and the tooth hub, then rotate the stop collar, make the relative spacing groove of stop collar of steel ball slide, the steel ball staggers and offsets with the stop collar inner wall with placing the hole on the stop collar, realizes the spacing fixed of steel ball. After the three steel balls are fixed in sequence, the pressure taking ring is arranged on the upper end face of the gear hub and presses the gear hub downwards, the gear hub can overcome the supporting force of the elastic supporting piece after being subjected to the downward pressure of the pressure ring and moves downwards along the axial direction of the gear sleeve, and the steel balls are driven to move downwards synchronously, so that the gear hub and the steel balls are accommodated in the gear sleeve, and the assembly is completed.

Among this technical scheme, through set up the mark on the terminal surface of stop collar, the accessible mark judges the position of tooth hub internal spring, and the position that the installation was treated to the steel ball promptly further makes things convenient for contrast and assembly, accords with operating personnel's operation custom and sight angle with its setting on the terminal surface, need not consider positive and negative restriction with the both ends of stop collar both ends in addition all set up the mark when using.

Preferably, as an improvement, the top surface of the mounting table is provided with a through air hole.

Among this technical scheme, when utilizing the clamping ring to push down the tooth hub, elastic support piece's holding power can be overcome to tooth hub and mount table and base lapse is followed to the holding power for the space between base and the mount table is compressed, makes inside pressure increase relatively, through the setting of gas pocket, can reach the effect of balanced inside pressure.

Preferably, as a modification, the top end of the mount table is provided with an annular groove for receiving the synchronizer hub.

The end faces of the inner teeth and the outer teeth of the synchronizer gear hub are protruded out of the end face of the gear hub, and grooves are formed in the end face of the gear hub of the synchronizer. Among this technical scheme, through setting up the mounting groove on the top of mount table, can form between the edge of mounting groove and the outer fringe of mount table can with recess complex annular protruding, play the effect of preliminary location, the assembly in the later stage of being convenient for.

Preferably, as an improvement, fillets are arranged between the top surface and the side wall and between the bottom surface and the side wall of the pressing ring.

Among this technical scheme, all set up the both ends of clamping ring into slick and sly structure, can avoid when pushing down the tooth hub, cause the tooth hub terminal surface mar to appear because of the sharp-pointed contact between clamping ring and the tooth hub, and all set up the clamping ring both ends into slick and sly, can the positive and negative use of reversing when using, broken the restriction of direction of use, convenience more.

Preferably, as an improvement, the upper portion and the lower portion of the pressing ring are both provided with smooth surfaces, and the middle of the pressing ring is provided with anti-skidding lines.

Among this technical scheme, all set up to glossy through the upper portion with the lower part of clamping ring, can avoid causing the damage to tooth hub terminal surface equally, the anti-skidding line at clamping ring middle part can increase when using with the frictional force of operating personnel hand, guarantees stably to take.

Preferably, as a modification, the number of the placing holes is three.

In this technical scheme, through setting up the quantity that will place the hole into three, adaptation that can be better is in the structure of steel ball formula synchronous ware.

Preferably, as a modification, the elastic support is a support spring.

In this technical scheme, through setting up elastic support spare into supporting spring, simple structure and equipment part processing technology are ripe.
