Description
Technical field
The utility model relates to the head of a kind of automotive service set, particularly a kind of car board spring bolt special puller.
Background technology
At present, on the market leaf springs of car bolt disassembly instrument is had three classes: the first kind is a spanner, by spanner the nut of spring bolt is applied moment of torsion and comes dismounting, such instrument effort, time-consuming, work efficiency is extremely low; Second class is manual leaf springs of car bolt disassembly device, by artificial input power, through deceleration force amplifier the nut of spring bolt is applied moment of torsion again and comes dismounting, and this class instrument is too heavy, inconvenient operation, work efficiency are lower; The 3rd class is an electric automobile spring bolt dismantling device, Chinese patent 2007200649050 discloses a kind of " electric automobile board spring bolt special puller ", it imports power by motor, through deceleration force amplifier the nut of spring bolt is applied moment of torsion again and come dismounting, its head as shown in Figure 1, its head is realized by adopting bevel gear pair in change transmission of torque direction, when adopting bevel gear pair that horizontal torque is changed over the torque of vertical-horizontal direction, contact between bevel gear wheel 51 and the lower cover 72 is sliding friction, because the frictional force that sliding friction produces is big, cause the inner cone gear very easily to wear and tear, reliability is low, and mechanical efficiency descends.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of car board spring bolt special puller head that adopts rolling friction between bevel gear wheel and case lid is provided, reduce frictional force between bevel gear wheel and the case lid by rolling friction, improve the mechanical efficiency of car board spring bolt special puller, prolong the service life of bevel gear simultaneously.
The technical solution of the utility model is: a kind of car board spring bolt special puller head, it comprises a casing, end face at the power intake of casing is provided with a flange coil pipe that has sealing ring, in the port of the power intake of casing, be provided with a single-row radial ball bearing, be provided with the power transmission shaft of a band bevel pinion in the axis hole of single-row radial ball bearing, bevel pinion is connected the back by the single-row radial ball bearing radial location with external splines in the power transmission shaft, and power transmission shaft is axially located bevel pinion.Be provided with a single-row radial ball bearing in the bearing block bottom the clutch end of casing, be provided with the large bevel gear shaft of a band bevel gear wheel in the axis hole of single-row radial ball bearing, bevel gear wheel is that the interior external splines of cylindrical straight gear involute is connected with large bevel gear shaft, and the lower end of bevel gear wheel is made axial location by large bevel gear shaft to bevel gear wheel with single-row radial ball bearing.Port at the clutch end of casing is provided with a case lid, case lid is fixed on the port of the clutch end of casing by bolt, be provided with a single thrust bearing on the face of cylinder of the bearing block of case lid and bevel gear wheel, radial and axial location is done by single thrust bearing in the upper end of bevel gear wheel.Be provided with a derrick crane axle in case lid, axle is laid with three planetary gears on derrick crane, and three planetary gears are installed on the derrick crane axle by planet pin, gear on the large bevel gear shaft and planetary gear engagement.
When car board spring bolt special puller was worked, torque was delivered to bevel pinion by power transmission shaft and is delivered to bevel gear wheel through the bevel gear pair engagement again, drives planetary gear output torque by large bevel gear shaft.Bevel gear pair is when changing the direction of transfer of moment, can produce big decomposing force, the decomposing force of bevel gear wheel as shown in Figure 2, X, Y are decomposing force, and M is torque, for better transmitting torque, the restriction extra dof, just must apply reaction force Nx, the Ny (decomposing force of reaction force N) of balance X, Y, decomposing force X, Y are directly proportional with torque M and cone angle a, and the frictional force of X, the big more generation of Y decomposing force is just big more.The utility model is by locating bevel gear wheel in the design of bevel gear wheel upper and lower side with single thrust bearing and single-row radial ball bearing, the balance decomposing force, the sliding friction that changes between existing head bevel gear wheel and the case lid is rolling friction, reduce the power consumption that overcomes friction, thereby raising mechanical efficiency, improve the engagement of bevel gear pair, prolong bevel gear pair service life.
The further technical scheme of the utility model is: described single thrust bearing comprises single-row tapered roller bearing, single row angular contact ball bearing and single direction thrust ball bearing.
The utility model compared with prior art has following characteristics:
Because the utility model has adopted technique scheme, comparing mechanical efficiency with existing car board spring bolt special puller head improves more than 20%, during the same nominal torque of design output, to the saving of resources such as electric power, motor and metal material with make full use of and all brought into play positive role.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
