Description
Technical field
This utility model relates to the technical field of engine fittings, specifically a kind of damper pulley assembly.
Background technology
Bent axle is the main revolving part in electromotor, and the reciprocating motion of piston is converted to the rotary motion of self by bent axle,
Other adnexaes are driven to work.
And the damper pulley on the bent axle of prior art is sequentially wound on multiple adnexa often by a belt,
Such as on the driven pulley corresponding to water pump, electromotor, air compressor machine, from there through the work rotating the whole adnexaes of drive of belt,
But in belt drive driven pulley rotation process, need the cornerite requirement meeting between belt and driven pulley, such as vibration damping skin
Cornerite between belt wheel and belt is more than or equal to 170 °, the cornerite between water pump driving wheel and belt more than or equal to 120 ° etc., when
Above-mentioned cornerite angle is too small less than the contact area between belt during technological requirement value and each driven pulley, frictional force is not enough, holds
It is easily generated skidding.Therefore when by rotating on a multiple driven pulley of belt drive, in order to meet cornerite requirement, above-mentioned
The installation site of each driven pulley can not be necessarily arbitrarily to arrange.And in actual application, the peace of each driven pulley
Holding position has certain technique matching requirements often, so the crankshaft structure of single race of the prior art cannot be simultaneously
Meet multiple driven pulley and the versatility of position and the requirement of cornerite are set.Prior art is sacrificed certain cornerite often want
Ask, or sacrifice the best position of driven pulley, for meeting the transmission of bent axle.
Summary of the invention

Detailed description of the invention
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.
This utility model provides a kind of electromotor bent axle, and it includes damper pulley, and one end of damper pulley is passed through
One bent axle wheel hub 2 is along the front end being axially mounted to bent axle 1 of bent axle 1, and one end of damper pulley and bent axle wheel hub 2 is fixed, bent
The other end of axle wheel hub 2 is fixed with bent axle 1 by a kingbolt 3, the extended line of the axis of the axis of damper pulley and bent axle 1
Conllinear, it is characterised in that: described damper pulley includes belt hub 4 and inertia rings 5, if one end of belt hub 4 is passed through
Dry auxiliary bolt 6 is fixed with bent axle wheel hub 2, and inertia rings 5 is placed on outside the belt hub 4 other end away from bent axle wheel hub 2, described skin
With wheel hub 4 away from the diameter of one end of bent axle wheel hub 2 more than the diameter of the other end of the nearly bent axle wheel hub 2 of belt hub 4, described skin
Axially sequentially be provided with, along belt hub 4, the race 7 that at least two diameter does not waits on lateral wall with wheel hub 4, for each
Corresponding belt matches.
The diameter of above-mentioned race 7 refers to the tooth root diameter of a circle of race.The tooth root diameter of a circle the most not phase of the most each race 7
Deng.
Above-mentioned bent axle wheel hub 2 refers to by kingbolt 3 is fixing with crankshaft body 1, and bent axle wheel hub 2 is provided with center and leads to
Hole, the front end of crankshaft body 1 is provided with the counterbore that the central through hole with bent axle wheel hub 2 matches, kingbolt 3 screwed
Thread part is through the central through hole on bent axle wheel hub 2, and coordinates with the counterbore threads on crankshaft body 1, the head of kingbolt 3
Compress bent axle wheel hub 2, make the front end fastening of bent axle wheel hub 2 and crankshaft body 1.
Described belt hub 4 is made for aluminum alloy material.
The outside of rubber ring 8, the internal ring of rubber ring 8 and belt hub 4 it is provided with between described inertia rings 5 and belt hub 4
The lateral wall tight fit of wall tight fit, the medial wall of inertia rings 5 and rubber ring 8.
The diameter of the diameter of the excircle of described inertia rings 5 crankshaft body 1 more than or equal to 2 times.
The quantity of described race 7 is two, inscribed figure radially inwards on the lateral wall of the less one end of belt hub 4 diameter
Becoming the race 7 that diameter is less, on belt hub 4, nearly inertia rings 5 position is relatively large in diameter spirogyrate on the lateral wall of one end
Becoming flange 9, on the outer circle wall of flange 9, inscribe forms the race 7 being relatively large in diameter radially inwards.Traditional bent axle generally requires
Drive the one or more of which such as one or more slave unit, such as water pump, electromotor, air-compressor set, and belt band
When dynamic driven pulley corresponding to above-mentioned parts rotates, need the cornerite requirement meeting between belt and driven pulley, i.e. ordinary circumstance
Under when cornerite less than 180 ° time easily produce skidding, affect the reliability of transmission.So, for the belt of single race 7
For wheel hub 4, when it needs to drive multiple driven pulley to rotate simultaneously, the installation site of described multiple driven pulleys can only be solid
Fixed several positions, for meeting the cornerite requirement more than 180 °.But in some application scenarios, the installation site of driven pulley needs
Meet the requirement of certain interference fit and assembly technology, so the two will produce certain contradiction.In prior art
Can only compromise selection, i.e. sacrifice certain cornerite and require or assembly technology requirement.Select two races 7 then can be at utmost
Guarantee cornerite requirement, so the installation site of each driven pulley can select at an arbitrary position, i.e. installation site is more flexible.
Described bent axle wheel hub 2 is provided with First terrace 10, and the front end of crankshaft body 1 is provided with and matches with First terrace 10
The second step face 11 closed, is formed between described First terrace 10 and second step face 11 and is used for installing at least one active wheel
Annular mounting groove 12.
